Linux resolution command?

[flawedreality5]

Hey everyone. I have to do some some school work on a live bootable Knoppix disc but the resolution looks like it maxs out at 1024x768 under the options for me. My LCD monitor's native resolution is 1280x1024 so 1024x768 looks really blurry. It there a command I can use for overriding the resolution? Thanks.

At the bottom of the first screen you see when knoppix boots you will see a boot prompt. You have about ten seconds to start typing something or the boot will proceed with the default parameters. At the boot prompt, type:

knoppix screen=1280x1024

then hit the Enter key to start booting.

My stupid USB keyboard drivers don't load until Knoppix boots up. I had to plug a PS/2 keyboard in to type the command, but it did work. I wonder if it's just this Saitek keyboard. It does the same thing going through Windows installation screens or trying to navigate the safe mode menus. Maybe I'll make a separate post for this problem. But thank you for the command.

Edit: Nevermind, enabled Legacy USB keyboard support in the BIOS. All is good now!

You need to edit your xorg.conf file.

From the command prompt:
nano -w /etc/X11/xorg.conf
Under the section for Monitor, set the HorizSync and VertRefresh values to what your monitor specifications are. Then restart X (Ctrl + Alt + Backspace). Now you should have the ability to set the resolution to a higher setting.

This is a bootable Live cd. The command before loading Knoppix is easier. Any changes saved to the file would be gone as soon as I restarted.

You are correct... guess I should read the entire post before replying! :)
