Configuring the Graphics Driver

Question I have just installed Linux onto my computer. My problem is that I can only get the screen to display in 640 x 480 resolution with 16 (4 bit) colours.

Answer: To configure X Windows to recognise your graphics card, you need to log on as root and go to a Linux command prompt prior to starting X Windows. Next you need to enter the command cd /usr/bin/X11 followed by ./Xconfigurator. This will run the configuration program allowing you to identify your graphics card and select your desired screen resolution and colour depth.

If your version of Linux boots straight into X Windows then you can shut down X Windows in order to run the Xconfigurator by pressing the CTRL, ALT, and Backspace keys all at the same time.

Once you have finished reconfiguring X Windows, you can start it up to test that your configuration works using the startx command. If you have configured support for more than one resolution then you can switch between them by pressing the CTRL, ALT, and + keys all at the same time. Once you are happy with your X Windows configuration, logoff from root and log back on using your regular logon name.
