Ubuntu: Unity Hints Tweaks and Tips

Ubuntu: Unity Hints Tweaks and Tips

Hey everyone I thought i should start putting more effort into this site so fortunately for all those who are regular visitors, I will now have regular weekly updates on our fav o/s. The bellow commands are compliments  of  wiki.indie-it . 

Autorun Media - Disable: How To

By default items such as optical media will autorun when placed in a drive, to disable this behaviour open 'dconf-editor' and locate the following key:
org.gnome.desktop.media-handling
Tick the box for 'autorun-never'

DConf-Editor - Install: How To

The dconf-editor is an essential tool for configuring Ubuntu, however it does not come installed by default.
terminal:~$

sudo apt-get install dconf-tools
After installation run from the launcher:
dconf editor

Desktop Switcher - Remove Icon: How To

This works for those who only require one workspace, if you want multiple workspaces but no icon this is not the fix for you.
Install compiz:
terminal:~$

sudo apt-get install compizconfig-settings-manager
In the Unity Launcher search for compiz and launch the manager application.
Under 'Category' click 'General' then 'General Options' click the 'Desktop Size' tab, then move all the available sliders to '1'.
Logging out then in should remove the icon from the launcher, if not reboot.
Cribbed here.

Global Menu - Disable: How To

NOTE:
There are things you should do however before disabling the Global Menu Support (GMS). Most programmes will revert to individual menus however there are exceptions and if these are not sorted before you remove GMS you will be left without the buttons to close/minimise/maximise:
Firefox: You need to disable the add-on/extension for Global Menu Support before remove un-installing the items above.
Linux Terminal:~$

sudo apt-get remove appmenu-gtk3 appmenu-gtk appmenu-qt 
sudo reboot

Global Menu - LibreOffice - Enable: How To

While LibreOffice is Ubuntu's default office suite does not come with Global Menu support for Unity out of the box. To enable support open the Software Centre and search for:
lo-meunubar
Highlight the result and click 'Install'.

Install ubuntu 13.4 in virtual box! 

Have you ever wanted to try Ubuntu but didn't have a spare computer to run it on? This tutorial will show you how a virtual machine like VirtualBox will let you play with other operating systems without having to change what’s on your computer right now. The tutorial will cover how to install VirtualBox and set up your first virtual machine, show you how to get Ubuntu and prepare for installation, and walk you through an installation of Ubuntu.

Post Install script example

Scripts add versatility and power to an already strong program. Downloading and installing them is an easy process. This process can also be applied to brushes, plugins, and gradients with some minor variations.
The easiest way is to gather all the commands you need and put them in a text file and make the text file executable.
Start out with implementing the  command line and do this:
touch post_install_script
sudo 775 post_install_script
gedit post_install_script
And you start putting in commands you want to be executed.
Installing packages that are in Ubuntu Software Center.
Start with enabling all repositories and refreshing the software list because the LiveCD is outdated:
sudo sed 's/# deb/deb/' -i /etc/apt/sources.list
sudo apt-get update
Look up inside USC what already is there and check the package name. Examples with VLC and smplayer:
sudo apt-get install vlc
sudo apt-get install smplayer
In the same way of adding software like this you can also remove packages with:
sudo apt-get remove {package_name}
(just be careful to check dependencies first)
PPA for installing nautilus elementary:
sudo add-apt-repository ppa:am-monkeyd/nautilus-elementary-ppa sudo apt-get update && sudo apt-get upgrade
Themes
Those are either in USC or have a PPA so you can add these with either one of the 2. For instance I like theequinox themes and I can add them like this:
sudo add-apt-repository ppa:tiheum/equinox
sudo apt-get update && sudo apt-get install gtk2-engines-equinox
or the Faenza icon sets:
sudo add-apt-repository ppa:tiheum/equinox
sudo apt-get update && sudo apt-get install faenza-icon-theme
So you gather all the installation instructions that you want to add and put them in your script each on a new line. You can speed things up by removing duplicate entries: sudo apt-get upgrade does not need to be done with every PPA: you can do that after adding all the PPAs but(!) before you install the software from the PPA.
Theoretically you can have 1 of these script files for all Ubuntu installations but you might need to tweak them for every system.
This is my newest attempt to creating a post install script:
enter image description here
What does this do?
  1. update sources list
  2. remove all directories in my home and create them again in /discworld2/ After that I recreate my home directory directories using symlinks. This way I am able to format my home and keep my files (they are not only on another partition but even on another disc);
  3. install software I want;
  4. set power management the way I want it.
  5. add ppa's I want
After installing I just execute my post_install file and it will run for a long time but it will take care of everything I want (well I will be adding more and more things over time so it will get longer).

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
