I installed on my Aspire E1-531 Xubuntu 14.04 and after the installation my brightness control is not working. I know this problem from Ubuntu 12.04.
There I could change the grub but in 14.04 it's not working because the don't accept sudo gedit /etc/default/grub - the answer is:
sudo: gedit: command not found
any ideas what i could do? Thanks!!
You need to install gedit first with:
sudo apt-get install gedit
Then you should be able to use:
sudo gedit /etc/default/grub
Ideally though, you should use gksudo or similar to run GUI stuff as root so bits of your home directory don't accidentally end up being owned by root. You can use a command line editor such as nano instead:
sudo nano /etc/default/grub
To use it simply edit stuff, then save with Ctrl+O and exit with Ctrl+X. You may need to install it first with sudo apt-get install nano.
After any apply changes, you should be able them by running sudo update-grub and rebooting.
