View Full Version : Changing screen resolution...

I have finished the hard drive install of Knoppix and would like to change the screen resolution to 800 x 600. How do I do that?

Thanks and regards,

You'll have to see if it's available in your XF86Config file. If not you can create it. The file is located here:

you'll want to look at /etc/X11/XF86Config-4

here is part of my file, look for this part in your XF86Config-4 file:

Section "Screen"
Identifier "Default Screen"
Device "Generic Video Card"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1152x864" "1024x768" "800x600" "640x480"

in the section that corresponds to your default display depth (as root) edit the file and either make a copy of the Modes line and comment the original out or just edit it so it something like:
Depth 24
#Modes "1152x864" "1024x768" "800x600" "640x480"
Modes "800x600" "640x480"

then save the file and restart your X server. Be careful because if you mess up you won't be able to run X, it's probably a good idea to make a backup copy of your existing XF86Config-4 file
