SaX.log file since the moment SaX2 is started from Yast2 to change the resolution till it exits

I have just installed openSuSE 10.3 on a Acer Travelmate 6291 notebook.

YasT2/SaX2 correctly guessed and setup the default video resolution 1280x800 .

However, when I want to change the resolution to 1024x768 or 800x600 which are listed in the SaX2 dialog as available resolutions, it does not switch. I try testing the new resolution before saving the settings, and it still shows 1280x800 in the test screen.

I tried saving with and without going through the test screen and it still does not work.

I restarted X using rcxdm stop ; rcxdm start and it still starts in 1280x800.

This is annoying because I need to make a presentation and the projector only supported 1024x768 0r 800x600 .

The only way I could make the video switch to 1024x768 was using the Screen Rotate and Resize utility. Fortunately the projector was able to pickup the new resolution, but I past attempts to do the same with other projectors that would not work. I would need to reboot the machine, but in this case it is always starting with 1280x800.

I am attaching /var/log/SaX.log, so you can check it out.

ah sorry I'm blind ;) Unfortunately the attachment doesn't help a lot
There is not enough information in there.

* The preferred way to switch the resolution for the new intel driver
  is using the randr extension (the rotate and resize utility) I don't
  know whether the driver accepts other resolutions than the panel internal
  one to start with
Comment 4 Stefan Dirsch 2007-11-02 14:34:17 UTC
This is a known issue. Indeed it is the preferred way to switch the resolutions on-the-fly for such purposes.

  xrandr --output LVDS --mode 1024x768 --output VGA --mode 1024x768_60

should do the trick.
