I am using ubuntu 11.04 on dell insprion 1545. But I am facing a problem that when I start laptop a message shows on the black screen that says
Ubuntu is running in low graphic mode. Your screen, graphic card and input device setting could not be detected correctly, you will need to configure these yourself
I have read that there is a file Xorg.conf that contain the graphics card information. I have also use the command
sudo cp /etc/x11/xorg.conf /etc/x11/xord.conf_backup
but its not working.
