use partial screen?

[eroth]

Hi,

I've got X11 and Gnome up and running on an old laptop with a 15.1 display and an s3Virge/MX gfx chip. Problem is that as the thing is old, there a pixel problem on the LCD at about the 5th pixel from the left the whole way down the screen.

question is: how can i set X or Gnome to only use a smaller section of the screen?

I've tried the lcd_center option in X, which is unfortunately super small in the center.
Also tried setting DisplaySize in the monitor...but it didn't seem to do anything.
I've gotten 800x600 to display in the correct area, but it's really fuzzy and horrible to read. 1024x768 doesn't work somehow...

here the relevant stuff out of xorg.conf:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"

Any help is greatly appreciated!

I'm pretty sure you can emerge fbset for this, it has screen margin setting, check the documentation for it, I've never used it myself.
