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

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")

Make wget, apt-get and aptitude use a proxy server

Just add this lines to your /etc/environment file...

Startup - Like autoexec.bat :)

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

1. Make the script with desired commands.
vi file.sh

2. Copy the script to /etc/init.d
cp file.sh /etc/init.d/file.sh

3. Change permission to allow execution
chmod +x /etc/init.d/file.sh

4. At /etc/init.d Link it!
sudo update-rc.d file.sh start 99 2 .
(do not forget the "." at the end of the command)


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