It seems X server didn't choose a good default for your monitor.

Does adding a option "PreferredMode" "1280x1024@60" to your monitor section solves this problem?

If yes, then we may need to add a quirk for your monitor to let it select the first detailed timing mode of your monitor.

Please attach xorg log with ModeDebug option turned on without the PreferredMode option.

Option "PreferredMode" "1280x1024@60"
to my monitor section solves this problem.

For the log file I removed the PreferredMode option and added

Option "ModeDebug" "YES"
to the device section.

I hope this is what you wanted me to do (I'm a linux rookie). Please find attached the Xorg.0.log

Many thanks, Martin

Please remove all modelines in you xorg.conf and also remove the preferredMode Option and try this patch (the patch is against Xserver).

With this patch, X server should be able to find the correct default mode for your monitor automatically.

Or if you have problem in compiling X server, you may use the modeline hack in your xorg.conf for now, and wait for you Linux OSV to release new X server with this patch integrated.

I will close this bug once the patch is commited into X server master branch.

Close, pushed to xserver.
