I saw something like that on my notebook, too - in my case, it was a
problem in the radeon driver which could be worked around by adding an
explicit "Modes" line in the used Display subsection in XF86Config,
like:

Section "Screen"
[...]
	DefaultColorDepth	24
[...]
	SubSection "Display"
		Depth     24
		Modes     "1024x768"
	EndSubSection
EndSection
