Running Fedora on Virtual Box and Changing Display Resolution

If you are wondering why changing your xorg.conf and adding 1024x768 to the display resolution doesn't change the default resolution of Fedora running under Sun Virtual Box, from the default 800x600, it is because Virtual Box assumes that you are using a CRT display rather than an LCD. You have to explicitly ask Virtual Box to use the LCD by issuing the following command as root -

> system-config-display

Thereafter you can go to the Hardware tab and select configure next to the Monitor type.

That will open the Monitor dialog where you can click on expand the arrow next to Generic LCD display and select the resolution that you would like.

Click ok on this dialog and the previous dialog and then restart Xserver by hitting Ctrl-Alt-Backspace or just by logging out and logging back in.
