My laptop currently has a screen resolution of 800x600, giving it a 1-inch thick black frame surrounding the screen, because the screen is intended for a 1024x768 resolution. Even my BIOS opens in 800x600 resolution. I have tried adding "vga=773" and "vga=0x305" to my menu.lst to at least get the startup text and initial shell to 1024x768, but this only gives me an error at boot (an error in which the fix is to remove the vga line from my menu.lst.)
My only idea is that I need to update the drivers of my video card. In the past I have used distributions that must have auto-updated my drivers, so I have never manually done this in linux. How do I go about updating my drivers in Arch Linux? Support would be much much appreciated.
edit: the problem may also have something to do with my HorizSync and VertRefresh values. How do I go about finding the correct amounts?
