Ubuntu 9.04 screen resolution ERROR
I started my computer, and booted it with Ubuntu 9.04, but the screen size was only filling 3/4 of my screen. So I tried to change the screen resolution, but the highest screen resolution was 800*600. I chose one lower down the list and applied it, but an error message came up saying it was an invalid screen size which bounced around the screen like a screen saver. I have tried pressing every key on the keyboard with every conceivable combination, but cannot get back to the desktop/settings to change it.
