After serious hard drive problems I've reinstalled everything and tested 3 configurations (on System "1"):

a) 2.6.31 (openSUSE, w/o your patches)
b) 2.6.33-rc5 (vanilla, w/o your patches)
c) 2.6.33-rc5 (vanilla, w/ your patches)

Results:
a) Problems when resolutions is changed with krandrtray (original problem, looks like "lost of sync" on crts)
b) Similar to a), but usually the monitor enters standby mode instead of showing the "lost of sync" pattern)
c) The monitor enters standby mode during booting. It seems that this happens when the i915 module is loaded (not when starting X as previously guessed). So I could not test what happens when resolution is changed with krandrtray.

So something has changed between 2.6.31 and 2.6.33, but this doesn't solve the problem. And unfortunately your patches also didn't help.

Christian

I'll be on vacation between Feb. 12 and Feb. 28
