CHanging KDE resolution

[andy4us1]

I was running X and KDE @1600*1200. I want to change down to 1280*1024. I can setup xfree OK, but when I start KDE still thinks the screen is 1600@1200 and I have to scroll the desktop. Where do I change the res for KDE ?

thanks

You could manually edit /etc/XF86Config and change the resolution there.

If you have to scroll the desktop, try (in the same file) to add/change the line to Virtual 0 0 and change the modes to "1280x1024/XXHz".


Section "Screen"
Driver "SVGA"
Device "Primary Card"
Monitor "Primary Monitor"
DefaultColorDepth 16
SubSection "Display"
Depth 8
Modes "1600x1200/70Hz" "640x480"
Virtual 0 0
EndSubSection
SubSection "Display"
Depth 15
Modes "1600x1200/70Hz" "640x480"
Virtual 0 0
EndSubSection
SubSection "Display"

Modes "1600x1200/70Hz" "640x480"

EndSubSection
SubSection "Display"

Changing the X resolution is the bit I can do, it's the fact that KDE still thinks the screen res is 1600*1200 that is the problem. X is displaying the screen res correctly. Kinda weird, X is displaying @ 1280*1024 and KDE is overlaying that with a screen that is 1600*1200,

It shouldn't if you have no reference to 1600x1200 in XF86Config.

Try adding the Virtual 0 0 or perhaps ViewPort 0 (I think). Have a look at the Xfree documentation installed with your distro or visit www.xfree86.org (http://www.xfree86.org)

Thanks, it was actually the 'Virtual 0 0' entry that did it. I had previously deleted the '1600*1200' entry but it was at that point I had the scrolling desktop .

thanks a lot,

Your welcome. Actually I suggested the Virtual 0 0 in the first post. Hence the reason I included the 'Screen' sections from my XF86Config.
