Interesting... I see that in your case the Sync to VBlank state
couldn't be determined either. But then the frontend continues, whilst
in my case it falls back to Qt...

Yes, you're right. In fact, I used to use NVidia GT220 before, with
proprietary NVidia drivers. Then I took it out, and got all this mess
with the built-in Intel video.

I reinstalled all the xorg-* packages. Also the output of 'glxinfo'
contains some interesting details. Full output is here:

From what I see there, the system still tries to use 'NV-GLX' -
something related to NVidia. The 'client glx' is also not clear:
'client glx vendor string: NVIDIA Corporation'

There are definitely some leftovers from NVidia driver. But I don't
know what else I should reinstall in order to get a clean system.

Maybe I will just get back to using my NVidia card. After all, I don't
have a major reason not to use it.
