Ubuntu 12.04 Post Install Upgrade Tweaks (Desktop)

 

Here are my Ubuntu 12.04 Post Install or Upgrade Tweaks:

1. Install MyUnity from Ubuntu software centre.

2. Install VLC player from Ubuntu software centre.

3. Install Google Chrome from https://www.google.com/chrome

4. Install Ubuntu Tweak:

sudo add-apt-repository ppa:tualatrix/ppa
sudo apt-get update
sudo apt-get install ubuntu-tweak 

5. Install VIM editor

 sudo apt-get install vim 

6. Disable Guest login:  change the allow-guest option to: allow-guest=false on the /etc/lightdm/lightdm.conf file.

7. Install pre-load:

 sudo apt-get install preload 

9. Install archey, a script that displays system info in a terminal:

sudo apt-get install lsb-release scrot
wget http://github.com/downloads/djmelik/archey/archey-0.2.8.deb
sudo dpkg -i archey-0.2.8.deb 

10. For laptop or netbook installations, install hardware temperature indicators:

sudo add-apt-repository ppa:alexmurray/indicator-sensors
sudo apt-get update
sudo apt-get install indicator-sensors 

11. Disable IPV6 (Optional) – edit /etc/sysctl.conf and add these commands:

 # IPv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1 

12. Disable or remove Zeitgeist**
Remove with caution and research first, it could break things!!
The safest way I’ve found is with this sequence of commands:

sudo apt-get --purge remove zeitgeist
sudo apt-get autoremove

Performance Tweaks:

Show Hidden Startup Apps:

 sudo sed -i "s/NoDisplay=true/NoDisplay=false/g" /etc/xdg/autostart/*.desktop 

Install Preload from Software Center:
Open software centre and search plus install the Preload package.

Change Swappiness Value:
Enter following line to see current swappiness value:

 cat /proc/sys/vm/swappiness 

(default value in Ubuntu for swappiness is 60)

Open /etc/sysctl.conf in a text editor:

 sudo vim /etc/sysctl.conf 

Enter your desired swappiness value at the end of the file:
# swappiness value
vm.swappiness=10
Save the file and restart the computer.
