adjusting screen resolution how?

Suffering from the expected error in detecting my video properly when installed 11.3.
Have intel 915G onboard video. Up until 11.1 Opensuse struggled with loading this correctly. Thankfully in 11.1 & 11.2 all was well. A couple of minor tweaks in sax2 and it worked perfectly.

Now hat sax2 has gone I’m not sure how to make these minor tweaks.

My problem is I have been forced to a screen resolution of 1024X768 VGA
Following the readme file adding nomodeset at boot fixes the problem but of course forces me back to an old video driver with pretty poor performance.

Is there any way I can change the screen resolution and set the correct monitor - any GUI replacement for sax2?
Krandrtray will only let me set a max res of 1024x768. I need to set res to 1280x1024

Have you tried doing an Xorg.conf file manually?

yes, found my old xorg.conf file from 11.2 and this has forced the correct video driver and resolution.
All of a sudden a lot of applications have become stable as well.

Really hope someone is working on some kind of GUI replacement for sax2
