Bug#427115: same problem here, related to latest Xserver/driver features

[Brice Goglin]

Hi,

I am having the same problem here with a i945 graphic board, but only
when using xserver-xorg-video-intel 2.0, not when downgrading to
xserver-xorg-video-i810 1.7 from Etch. I see Damian has an Intel board
too, so I would bet he is using these Intel driver 2.0 too.

This driver is the first one to implement RandR 1.2 support (great stuff
to manage/resize/move multiple monitors at runtime). There has been some
changes in the way the Xserver (since xserver-xorg-core 1.3) manages
video modes for RandR 1.2. So the problem might be that fretsonfire (or
the underlying python libs or so) are not querying/choosing video modes
in a RandR-1.2-compatible way.

Or it could be a bug in the Xserver and/or the Intel driver, but...
I am also seeing some problem when switching from the official ATI
driver 6.6.192 (seems to work fine) to the upcoming RandR 1.2 one (black
screen). I am not going to talk more about it until this new driver is
officially released. However, it seems to prove that fretsonfire does
not like recent features of the Xserver.

I don't think the problem is GLX related (I am pretty sure GLX works
fine in my server). By the way, the previously cited libGL warning is
known to be harmless (see
https://bugs.freedesktop.org/show_bug.cgi?id=6689).

Hope this helps.
