Problems with video card?

Have you seen this screen recently??



Before you reinstall your Ubuntu, check out this tip:

If you changed something on your Linux configuration regarding video you can easily solve your problem returning your old /etc/X11/xorg.conf

In most cases we do not have a backup of this file until we need it. In this case you can reconfigure your system with this command:

sudo dpkg-reconfigure xserver-xorg

Just follow the screen instructions. A Vesa video work fine for most boards in an emergency.

CPU scaling

When you are using a laptop CPU scaling helps you to save power on batteries or give you better performance when connected to AC power.

Just add the applet to some of your gnome panels and change the permissions of file /usr/bin/cpufreq-selector with this command:

sudo chmod +s /usr/bin/cpufreq-selector

Then you will get this icon showing you the processor speed...



Clicking over it you can choose the best profile to use.








Is this information useful?? So remember to Thumb it up!!!

Cedilla / Cedilha Problem (ć to ç)

a very common problem to Brazilian users with U.S. International keyboard. Still with the problem on Feisty...
When you press ' + c you get ć instead of ç.


Edit as super user the file "/etc/gtk2.0/gtk.immodules" and replace

"cedilla" "Cedilla" "gtk+" "/usr/share/locale"
"az:ca:co:fr:gv:oc:pt:sq:tr:wa"

with

"cedilla" "Cedilla" "gtk+" "/usr/share/locale"
"az:ca:co:fr:gv:oc:pt:sq:tr:wa:en"

Useful files

Some files used to configure your system. This list will be increased soon...

With this you can change your boot order.
/boot/grub/menu.lst

Environment variables
Paths, proxies and misc. variables usable globally. (i.e.: "PATH=/bin")
/etc/environment

Partitions

Startup - Like autoexec.bat :)

This script will run before the graphical interface appears...

1. Make the script with desired commands.

2. Copy the script to /etc/init.d

If you need to disable this script in a near future:
sudo update-rc.d -f file.sh remove
