guide to Installing the Latest Nvidia Drivers in Ubuntu 13.04


Need Help With Ubuntu
Join Now Only $5.50 USD
Ubuntu 13.04 (Raring Ringtail) has been launched, and some of the problems we had in the past with the Nvidia proprietary drivers have been fixed.The installation has been made a lot easier  users like myself can still do it the old fashion way, in a terminal.

Canonical has opted to enable by default the Nouveau drivers for Nvidia, in Ubuntu 13.04 (Raring Ringtaail). Unfortunately their drivers are not as good as the one developed by Nvidia.

I prefer working with commands so I will give you the way I had did it

Log out of the system and press Ctrl + Alt + F1. Log in into a command line interface, navigate to the folder where you have downloaded the driver, and kill the LightDM display manager:

sudo service lightdm stop
sudo chmod a+x NVIDIA-Linux-x86_64-313.30.run
sudo ./NVIDIA-Linux-x86_64-313.30.run

All you have to do now is wait and follow the on-screen instructions. You might need to perform this operation twice if the Nouveau driver is active. 

When the installation is done, enter the sudo reboot command and enjoy the newest Nvidia drivers.

Facebook, Twitter & Ubuntu Lucid Lynx

Former Ubuntu logo. New version at File:Ubuntu...
PCs running Ubuntu will be getting more social thanks to changes that will set the popular Linux distro's look and feel for the next five years.
Lucid Lynx, released last April, will bring social applications like Twitter and Facebook directly into the software, Ubuntu founder Mark Shuttleworth has said in an interview here.

Apparently, the idea is to merge the desktop and online worlds, so people don't have to fire up their browser or a separate application to use their social applications.

Also coming is what Shuttleworth called "new styling" for the Lucid Lynx desktop. He didn't provide further details, but Shuttleworth has been a consistently keen advocate of the need to improve the design, not just the user experience, of Linux through Ubuntu.

"There will be some shiny, new bling on the desktop - we will have some new styling, which is going to be the starting point of another five-year view. We've bee human for the last five years - now we are going to be light oriented," Shuttleworth told Dell's cloud computing evangelist Barton George.

Shuttleworth also promised big changes for the version of Ubuntu targeting netbooks after Lucid Lynx.
Shuttleworth on March 1 will step down as chief executive of Canonical, the commercial sponsor of Ubuntu, and take on a more technology oriented role, working on Ubuntu. He said he's putting "a lot of time" into the Ubuntu Netbook Remix, saying it will go through what he called a period of rapid evolution in the next cycle after Lucid Lynx.

He also claimed that Linux - and particularly Ubuntu - is growing on netbooks in the wake of Microsoft's release of Windows 7 and the disappearance of Windows XP.

"There was some speculation around the death of the netbook," Shuttleworth said. "We haven't seen that. With Windows 7 out there, people have a real choice between free software and proprietary software, and it turns out free software is a popular choice.

"The share of Linux on netbooks seems to be growing now that XP's getting downplayed and we want to be right in the thick of that."
He was also optimistic about uptake of Ubuntu on mobile devices like smart books and said he was starting to see innovation around ARM-based devices since the release of Ubuntu 9.4 that officially put the disto on this hardware architecture popular in mobile devices.

Ahead of that, Lucid Lynx will have a "strong focus" on cloud, which as an LTS release is a major milestone. Lucid Lynx will rollout as people put into production the clouds they've built and tested on features that were introduced in Ubuntu last year for users to build Amazon EC2 images on their Linux systems.

"WOW" All in one script to tweak Ubuntu after a fresh installation!


Need Help With Ubuntu
Join Now Only $5.50 USD

I had a few fresh installs of Ubuntu 10.4 Lucid lynx to complete this week for friends and family, usually i go through the normal adding repositories to the sources list and installing the usual software we all need to operate our daily computer lives. I came across the information below from the boys at WebUpd8, I have run the script provided and feel it saved me some time. Hope you like it too!


A new version of "What to do after installing Ubuntu? Run this script!" has been released. The script now has an actual name: "Ubuntu 10.04 Start".

For those who've used the first release of the script: since a few versions ago, you can select which applications to install and which tweaks to apply from this script so if there's something you don't like, all you have to do is not select it!

Instead of a changelog, I'm going to list all the features again:
  • Adds extra repositories: Ubuntu restricted, extras, Medibuntu, Getdeb, Dropbox (only if you select to install Dropbox)
  • Installs from repositories: The GIMP, Pidgin, WINE, Choose between the best 3 docks for Linux (Docky, Cairo Dock and Avant Window Navigator), Install Google Earth, Bisigi Themes, Community themes (and extra community themes), Chromium browser, Gnome Do, Guake, VLC media player, Mplayer, SMplayer, Thunderbird, Dropbox, Codecs (multimedia, java, flash), additional archives support, DVD support and fonts, Ubuntu Tweak, Deluge Torrent, CompizConfig Settings Manager, Development tools (from build-essential to Subversion, GIT and so on).
  • Downloads and installs the following: Google Chrome browser (will download the build for 32 or 64 bit, depending on your Ubuntu version), official smiley themes for Pidgin (for all the protocols), the latest Flash Player for 64bit via Adobe's website, Skype (32 or 64bit, depending on your Ubuntu version).
  • Tweaks:


    • Move window buttons to the right (Karmic style)
    • Change Update Manager behavior to the one in Jaunty
    • Remove mounted drive icons from desktop
    • Disable the GDM login sound
    • Enable the icons in menus and buttons
    • Disable the GDM login user list
    • Remove the ubuntu-docs package (frees up 252MB)
    • Change Gnome Calendar first day of the week from Sunday to Monday
    • Downloads, installs and configure sharp fonts (starting with version 0.4.5: also installs sharp fonts for Firefox)
    • Fix 'apt-get update' delay for Google repository
    • Automatically mount NTFS drives on startup

  • Option to reset any changes made by the tweaks (tweaks only!) (stating with version 0.4.5)
  • Automatically accepts the JAVA and Google Earth license so you don't have to
  • The Medibuntu server is currently down which made me develop a new feature: the script now tests the main Medibuntu server and 2 other mirrors and adds whichever of these 3 is working.
  • Lots of checks to make sure you run the script proprely: will check if the script is ran as root, if Synaptic, apt-get, dpkg or Software Center is running and will ask you to close it before running the script, checks the internet connection to make sure you can actually install the packages, etc.
The new version also fixes lots of bugs from the previous version.

Why would you want to use Ubuntu 10.04 Start?

The main purpose of this script is to speed up configuring Ubuntu 10.04 immediately after you've just installed it. This includes both installing popular applications and codecs as well as fixing some annoyances in Ubuntu 10.04.

You can search for each package in Synaptic or Ubuntu Software Center and manually install it. But then you'll also need to go to the Skype website and manually download and install it (Skype is no longer available in the Medibuntu repository), the same for Google Chrome, and so on. You can also use Ubuntu Tweak for some tweaks (but only a few of the tweaks in this script). But this script combines the most popular tweaks which are not available in a single application with installing common packages which almost everyone uses, so the time spent configuring Ubuntu 10.04 is decreased dramatically.

The script should also help new Ubuntu users since the script configures lots of things without any input from the user (such as automounting NTFS drives on startup and so on).

Download and run the Ubuntu 10.04 Start script

Remember it's not recommended running a script without knowing exactly what it does, so I invite you to look at the code before running it.

Note: The script comes with no guarantees. Use at your own risk!

To install Zenity (required by the script), download and run the script, copy / paste the following commands in a terminal:
sudo apt-get install zenity
wget http://launchpad.net/ubuntustart/0.4.x/0.4.9/+download/ubuntu-10.04-start-0.4.9.10.tar.gz
tar -xvf ubuntu-10.04-start-0.4.9.10.tar.gz
cd ubuntu-10.04-start/
sudo ./ubuntu-10.04-script

You can also manually download the latest version from https://launchpad.net/ubuntustart/+download

A few explanations on the tweaks:

Move window buttons to the right (Karmic style) - will move the Metacity window buttons to the right side, in the following order: Minimize, Maximize, Close

Change Update Manager behavior to the one in Jaunty - Ubuntu 9.04 (and newer) introduced a change to the handling of package updates, launching update-manager directly instead of displaying a notification icon in the GNOME panel. Users will still be notified of security updates on a daily basis, but for updates that are not security-related, users will only be prompted once a week. This tweak makes the update-manager not pop-up, but always show the updates in the notification area.

Remove mounted drive icons from desktop - removes ntfs and usb drives from the desktop; usually when mounting a drive it shows up on the desktop

Disable the GDM login sound - all the sounds in Ubuntu can be turned off from a GUI except this one. This is the sound produced when the GDM login screen loads.

Enable the icons in menus and buttons - the icons in menus and buttons were removed in Gnome 2.28 (starting with Ubuntu Karmic). However, up until Lucid, users were able to enable these from the Appearence dialog preferences. This is no longer possible so use this tweak instead.

Disable the GDM login user list - in Lucid, the user list is displayed in the GDM login screen (which IMO is a security concern). This fix will make no user show up in this list, and for logging in you must enter your username and password manually.

Change Gnome Calendar first day of the week from Sunday to Monday tweak - Gnome Calendar comes with Sunday as the first day of the week. This tweak fixes this for non-US citizens.

Remove the ubuntu-docs package (frees up 252MB): removed the ubuntu-docs package to free up 252 MB of disk space.

Install and configure sharp fonts: info about this feature, here: http://www.webupd8.org/2009/09/ubuntu-debian-script-to-install-sharp.html

Fix 'apt-get update' delay for Google Chrome repository - when downloading Google Chrome .deb, it automatically adds the Google repository. The same goes for Picasa, etc. This repository has a known issue which cause "sudo apt-get update" to take a very long time to complete. This tweak fixes this issue.

Add additional repositories (GetDeb, Medibuntu etc.) - Adds the following repositories: Getdeb, Medibuntu, Ubuntu universe and multiverse and lucid partner.

Note: I am no expert at BASH, so the script code will look very unpolished to some. But it works :)

The Ultimate Ubuntu XBOX 360 Multimedia Sharing Guide

NOTE: Since the Fuppes UPNP project has gotten its act together I consider that project a superior solution to ushare. I have some basic instructions for compiling SVN fuppes at the end of this thread as currently there is no fuppes package available in the Ubuntu repos. Possibly when my 360 comes back from repair I will consider updating the guide unless someone does it before me.

So your using Ubuntu and you want to share multimedia from your machine to your 360. This is indeed possible! Some of you may ask, there is a number of existing guides about this, so whats different about this one? Well, this guide uses free software and it uses free software that is not encumbered with bugs.

At the heart of the matter is that we need whats called a upnp media server to serve the media requests. Microsoft in typical fashion did not adhere to upnp standards when producing the 360's sharing. So that means right off the bat, upnp media servers will not work. Thankfully though, some upnp media servers have been modified to run in a special xbox 360 mode. The bad news is that these select servers are either not free or not robust.

The community has reached a point where the single robust upnp server that is free, and importantly is not deprecated, does not have the special xbox 360 mode. Servers like 360 media serve and Fruppes are not actively being developed. The Fruppes community is talking about merging with MediaTomb but getting 360 mode into MediaTomb is going to take time. Ushare is still being developed but it contains a number of ugly bugs that makes the experience frustrating. There is a payware upnp media server but in our hearts, we know that using non free software really isnt right.

Thanks to forum member NeToU he has taken the Ushare source code and patched it to resolve these ugly bugs. So we will be using his patched Ushare version.

Were going to need to download his source code, configure it, compile it and install it. This is not as hard as it sounds and provided you can follow these instructions carefully you will do fine.

NOTE: YOU MUST REMOVE AND PURGE ANY OLD USHARE INSTALLS YOU MAY HAVE FROM THE REPOS BEFORE STARTING

1. Download The Source

Goto http://netou.co.uk/ and download the source code.

2. Extract The Source

I keep my source in a directory tree under home / src though you may use a different approach. Open up a terminal by selecting the Ubuntu icon, Accessories and then Terminal. Now carefully copy and paste the following, one line at a time, hit enter in the terminal and do the next line.














Code:
cd ~
mkdir src
Now move your archive to the src directory depending on where you downloaded the source too. For example, if it is in your home directory use:


Code:
mv ~/ushare-11a-netou.tar.bz2 ~/src/
Lets extract the source now:


Code:
cd ~/src
tar -xjf ushare-11a-netou.tar.bz2
3. Compile the program

First lets get the dependencies out of the way. If your not sure if you already have these there is no harm in doing it as existing installs will not be installed again. So lets get the tools to be able to build software:


Code:
sudo apt-get install build-essential
Now lets deal with getting the software Ushare depends on:


Code:
cd ushare-1.1a-NeToU
sudo apt-get build-dep ushare
Once that is done, we can compile Ushare now:


Code:
./configure --prefix=/ --bindir=/usr/bin --mandir=/usr/share/man
make
sudo make install
sudo make clean
4. Configure Ushare:

Ushare like most Linux apps has a conf file. It is critical that you enable the special xbox 360 upnp mode and that you correctly put in the path of the multimedia that you want to share. To edit you conf file, use the following command:


Code:
gksudo gedit /etc/ushare.conf
Or use nano in the CLI:


Code:
sudo nano -w /etc/ushare.conf
Edit the file to your liking, with the important settings explained below:



Code:
USHARE_NAME=          Put the name you want your share to be called e.g. MyMedia
USHARE_PORT=          Define the port number you want to use e.g. 49200
USHARE_DIR=           Configure the share locations e.g. /mnt/hda1,/mnt/hdb1/videos/share/
USHARE_ENABLE_WEB=    Use yes to enable the web interface
USHARE_ENABLE_TELNET= I turn this off with no, preferring to use the web interface
USHARE_ENABLE_XBOX=   This must be yes for 360 sharing to work
Note that Ushare does not handle spaces in the share directories.

5. Controlling the Ushare daemon

To start Ushare:


Code:
sudo /etc/init.d/ushare start

And to stop Ushare:


Code:
sudo /etc/init.d/ushare stop
6. Getting Ushare to automatically start on user login:

Some of the existing guides that use not so robust Upnp servers, also recommend unnecessarily complex ways to get Ushare to autostart. For example by hacking up sudo to run Ushare as a session item for the user. This approach is not only messy, but it also creates the problem where if that user logs out and then later logs in again without rebooting you now have multiple Ushare sessions going.

Let's get Ushare to auto start using Ubuntu's default runlevel settings:



Code:
sudo update-rc.d ushare defaults
7. Managing Ushare via the web interface

You can manage Ushare via the web interface at:


Code:
http://ip_address:port/web/ushare.html
For example on my machine, its http://192.168.10.2:49200/web/ushare.html

8. Wait, I have the firewall on!

If your using Ubuntu's UFW, you can easily add a rule to cope with this. Lets say your 360 uses a static IP address of 192.168.10.3 and your machine is 192.168.10.2. Use the following command to provide a small hole in your firewall for this:



Code:
sudo ufw allow proto tcp from 192.168.10.3 to 192.168.10.2 port 49200
You can easily check what UFW is doing with:



Code:
sudo ufw status



FAQ #1 Why Cant I Transcode?

You can easily! However the best way is to do this outside of a upnp server. Why? The elegant way to do it otherwise is coding a media centre extender. However Microsoft's 360 media centre does not support MPEG4-ASP (divx, xvid) among other things - yes it is behind the "dumber" sharing interface without the media centre. This complicates coding a media centre add on.

There is robust and verstile Linux apps you can use to easily transcode media. I consider the best to be mencoder which can quickly convert many different media formats into mpeg2. You could even batch script it to convert directories of your media overnight.

FAQ #2 I Want to Uninstall



Code:
cd ~/src/ushare-1.1a-NeToU/
sudo make uninstall
sudo update-rc.d -f ushare remove

Setup easy web development environment (XAMPP)

vector version of this imageImage via Wikipedia
This is a how-to for setting up a web development environment easily. This guide will install the XAMPP lampp stack into /opt, setup an easy way to start it up and shut it down, and link a folder in your home directory to the webserver.

WARNING
This guide is aimed at a development environment only and should not be used as a public webserver. To setup a public webserver follow the directions on the Ubuntu wikihttps://help.ubuntu.com/community/ApacheMySQLPHP

As this is Ubuntu, all the major parts of a typical web server are included (in the main repo, or on the Ubuntu Server CD) and this is a great way to setup a server. The ubuntu developers have prepared a great web server and have made the process as seemless as possible.

But what if even the official way is still to complicated? What if you just want a quick web server for development?

Fortunately there is the XAMPP project: http://www.apachefriends.org/en/xampp.html. The XAMPP project bundles Apache, PHP4 & 5, Perl, mySQL, and a bunch of other utilities/applications into an simple package for Mac OSX, Windows, Solaris, and Linux. Obviously this HOWTO only deals with the linux version.

For those of you with already existing Apache/mySQL/php installations it installs everything into /opt so it doesn't conflict with any other installation, and it is completely setup and ready to run.

Install XAMPP

Two easy steps:








  1. Download the most recent version of XAMPP: (at time of writing 1.5.3a)
    http://prdownloads.sourceforge.net/x...ar.gz?download
    (Source URL: http://www.apachefriends.org/en/xampp-linux.html#374)
  2. Extract the archive to /opt using sudo: (make sure you are in the directory that you downloaded the archive to)



    Code:
    sudo tar xvfz xampp-linux-1.5.3a.tar.gz -C /opt

Start XAMPP

To start it up, open a terminal and type this:




Code:
sudo /opt/lampp/lampp start
Stop XAMPP

To stop it, open a terminal and type this:



Code:
sudo /opt/lampp/lampp stop
Additional XAMPP commands

To see additional commands, open a terminal and type this:



Code:
sudo /opt/lampp/lampp
Sweet XAMPP Control Panel



To use the sweet gtk/python control panel:

Run in a terminal:



Code:
gedit ~/.local/share/applications/xampp-control-panel.desktop
Paste the following into the open file and save and exit.



Code:
[Desktop Entry]
Comment=Start/Stop XAMPP
Name=XAMPP Control Panel
Exec=gksudo "python /opt/lampp/share/xampp-control-panel/xampp-control-panel.py"
Icon[en_CA]=/usr/share/icons/Tango/scalable/devices/network-wired.svg
Encoding=UTF-8
Terminal=false
Name[en_CA]=XAMPP Control Panel
Comment[en_CA]=Start/Stop XAMPP
Type=Application
Icon=/usr/share/icons/Tango/scalable/devices/network-wired.svg
"XAMPP Control Panel" will show up in your applications menu under Internet. Use the Alacarte Menu Editor to move it around.

Test to see if XAMPP is running

Once XAMPP is up and running open firefox and go to: http://localhost/

You should see the XAMPP test page:



Location of files and uploading

XAMPP by default uses /opt/lampp/htdocs as the root web directory. The easiest way to start working on files is to link a folder in your home directory into this directory.
My user name is peter so I have /home/peter/public_html linked to /opt/lampp/htdocs/peter. So if I navigate to http://localhost/peter/ I get a listing of all the files/folders in that directory. (As long is there isn't a index.php/html/etc file)
To set this up, run in a terminal:


  1. Make public_html directory in home directory:



    Code:
    mkdir ~/public_html
  2. Link to /opt/lampp/htdocs



    Code:
    sudo ln -s ~/public_html /opt/lampp/htdocs/$USER
Now any files and folders you place in ~/public_html will be published to your personal webserver.

Bookmark http://localhost/username to make this easy to access.

WARNING - SECURITY
http://www.apachefriends.org/en/xampp-linux.html#381
Open holes:



  1. The MySQL administrator (root) has no password.
  2. The MySQL daemon is accessible via network.
  3. ProFTPD uses the password "lampp" for user "nobody".
  4. PhpMyAdmin is accessible via network.
  5. Examples are accessible via network.
  6. MySQL and Apache running under the same user (nobody).
This doesn't leave your whole system wide open, but someone could hack your XAMPP installation, so be wary.
To fix most of the security weaknesses open a terminal and run:


Code:
sudo /opt/lampp/lampp security

Known Lucid Lynx issues/bugs with workarounds

ubuntu bug jamImage by ebel via Flickr
I got this infomation from the Ubuntu Forums thought someone may find it useful.


The purpose of this post is to list known Lucid Lynx issues and bugs, and give the corresponding workarounds and launchpad entries.

Feel free to propose other known Lucid Lynx bugs to be listed here but please provide a link to the workaround and a link to the corresponding launchpad entry.

-------------------------------------------------
Warning: Before upgrading or attempting a reinstall make sure you backup essential files.
Please read the Release Notes:-

http://www.ubuntu.com/getubuntu/releasenotes/1004
Upgrade 8.04 -> 10.04 can break apt-get.
The package flashplugin-nonfree has been problematic when upgrading 8.04 -> 10.04 and breaks apt-get;

Bug Report

For those not wanting to read the bug report in detail, the fix is :













Code:
sudo rm /var/lib/dpkg/info/flashplugin-nonfree.prerm

sudo dpkg --remove --force-remove-reinstreq flashplugin-nonfree
sudo dpkg --purge --force-remove-reinstreq flashplugin-nonfree
Nautilus location bar, bread crumbs vs text based.
Breadcrumbs is now the default. The button to switch between the two has been removed. Users can switch with ctrl+l and then esc to revert to breadcrumbs. To permanently switch to text users have to use gconf-editor from a terminal. Note: gconf-editor has been removed from the menus. The key is.
apps>nautilus> preferences> always_use_location_entry


Minimize, Maximize and Close button placement.
A decision has been taken to move the placement to the left. Mark Shuttleworth explained that this was because "something" is going to be placed in the right hand area in the next release. Moving the buttons now would help enable this change.
[Update ]http://www.markshuttleworth.com/archives/333

The buttons are in the old location on all default themes apart from Ambiance,Radiance and Dust, If you still want the Ambiance ,Radiance or Dust theme but with buttons on the right, choose one of those other themes and use the Customize button to achieve what you want. e.g.
1. System > Preferences > Appearance
2. Select the theme icon "New Wave"
3. Click the button "Customize.."
4. Select tab "Controls" and select "Ambiance"
5. Select tab "Window border" and select "Ambiance"
6. Select tab "Icons" and scroll down and select "Ubuntu-mono-dark"
7. Select "Save Theme" to your choice.
Using gconf-editor is not the right approach as this could bork future themes. This change makes it easier for themes to do interesting things with window borders. Unfortunately, if the wrong approach spreads, they won't be able to do that.


Problem with Huawei and possibly other usb mobile broadband dongles. 
Please see this bug report and click the affects me button if you have this bug.
Try this first












Code:
sudo apt-get install usb-modeswitch

Graphical solution : http://news.softpedia.com/news/How-t...4-140810.shtml

Command line :
(Some of the fixes put forward dont work for everyone.)
One that works for nVidia and to try is this.












Code:
gksu gedit /etc/default/grub
and add the line in BOLD.
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=500x480
GRUB_GFXPAYLOAD_LINUX=1680x1050 Save the file and run











Code:
sudo update-grub
The resolution chosen should be your monitors native resolution.

Other graphics card users including nVidia may get a black screen with flashing cursor and then a very short duration plymouth.

One fix for this is to create this file.












Code:
gksu gedit /etc/initramfs-tools/conf.d/splash
and add this option FRAMEBUFFER=y, save the file.
Then












Code:
sudo update-initramfs -u
Plymouth now has a hard dependency on mountall thus trying to remove Plymouth would remove half the OS. The advice is, if you don't want a graphical boot then uninstall any plymouth themes.

If the problem is a slow boot, and you have no floppy drive, disable the floppy in the bios. This has been reported as a fix to this.

If the problem is plymouth not displaying, and a black screen from grub to gdm, this could be due to graphics drivers needing to be loaded quicker. This is bugged.

Plymouth is installed with 2 themes by default you can install more via synaptic.
To change themes this code is used.













Code:
sudo update-alternatives --config default.plymouth
Java. 
Sun java has been deprecated. Openjdk is now the default, i.e installing ubuntu-restricted-extras with recommends will install openjdk and the icedtea plugin. Openjdk has been certified by Java SE Test Compatibility Kit (TCK) and is compatible with the Java(TM) SE 6 platform on the amd64 (x86_64) and i386 (ix86) architectures. However sun-java is in the partner repo.
There's a bug regarding the icedtea plugin and certain applets.

Not fixed yet. Workaround may be to create a new Firefox profile.


Boot options hidden by default on Desktop and Netbook LIVECDs

To configure advanced boot options, press any key at the first boot screen.


Scrolling with ALPS Laptop Touchpads
Various users who have ALPS touchpads have reported that scrolling no longer works in the final release. A bug report is already open on the case, and the current workaround is to run:












Code:
sudo rmmod psmouse
sudo modprobe psmouse proto=imps
If this works, you can make it permanent by putting:












Code:
options psmouse proto=imps
At the bottom of the file /etc/modprobe.d/options


Ubuntu shuts down after unplugging Laptop power cord
A problem known with MSI wind and some Vostro users.

Current workaround is to open gconf-editor and browse to:












Code:
/apps/gnome-power-manager/general
And de-select the option use_time_for_policy

There is no need to restart, just close the configuration editor.












A lot of users are overwriting their windows boot sector due to a confusing message with the grub2 install. It says something like 'Choose where to install grub. If you are not sure select all partitions'. And this leads some to select their windows partition.

NOTE: if you are reading this before you upgrade, the only place you should install grub is to the drive you are booting from. For most people it's /dev/sda . If you installed from within windows (a WUBI install), do not install the grub2 bootloader - leave all boxes unchecked.

The fix and diagnosis is at:

This is not the same as the bug that caused the re-release of certain iso's. That had to do with the windows not being listed in the grub menu. In this case, the windows option is listed but fails to boot.

There is a rather permanent problem with the propietary ati drivers. Maximizing and unminimizing is terribly slow with compiz enabled. There are several workarounds, however. You could either try the no-backfill xserver, the back-clear patch or enable Direct2D.

Direct2D can be enabled with the following steps:

1. backup your current xorg.conf

~$ cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak


2. delete the contents of xorg.conf

3. let aticonfig make an initial configuration:
~$ sudo aticonfig --initial

4. then enable Direct2D:
~$ sudo aticonfig --set-pcs-str=DDX,Direct2DAccel,TRUE
I personally prefer the backclear patch as I noticed that although the maximizing issue is reolved with Direct2D, scrolling in for example emacs becomes totally sluggish. You can find more information on the backclear patch here:
