Hi Yuri,

Cool, thanks for the photo. I've just recently started looking into X
bugs, so if you can point me to additional reports about this I would
very much appreciate it.

Here's a few guesses, could you guys let me know what you think on them?

1.  It could just be the monitor settings.  If the monitor does have
some manual controls on the front of them, that's the first thing to
try.  Yuri - I couldn't see if your monitor has H/V adjustment controls?
Your monitor also looks like it could use some pincushion adjustment as
well.

2.  Xorg may have failed to detect hardware H/v rates and may be
selecting a resolution that your monitor clips.  A LOT of people have
been reporting various issues related to improperly detected monitor H/V
rates, resulting in misdetected resolutions.  This shows up as a
descrepancy between the /etc/X11/xorg.conf file and the
/var/log/Xorg.0.log file.  If those of you experiencing this problem
find that #1 doesn't seem suitable, please upload these two files here
in this bug, and we can take a look at them and see.  For people that
find running xvidtune fixes the issue temporarily, that makes this sound
like a likely reason.  The workaround for this is to make absolutely
sure the hsync and v refresh rates exactly match your monitor's
documentation (X ought to be able to detect your monitor settings, but
it proves to be rather hit or miss).

3.  Driver issue.   Martins, you suspect a driver issue and you could
very well be right.  I'd like to rule out #2 first, especially since you
notice it sometimes works and sometimes doesn't.  If it's a driver issue
then I'd expect it to not work all the time, but the monitor
misdetection can sometimes have a random nature to it.

4.  Something completely different.  Possibly it's a known xorg bug, in
which case we can check the freedesktop.org bug tracker.  But first
let's try ruling out the above.
