After resuming from standby or leaving the computer locked for a while
I come back and I get a partial video freeze, the mouse cursor moves
but won't change from pointer to anything else. The rest of the
display is completely frozen but I still have access to the computer
remotely and SysRq keys are working correctly, I can even put the
computer back in standby and resume it. Finally everything works
except the display is completely frozen to the last displayed image +
cursor moves.
Is there something I can do to debug this problem, I also reported a
bug about Google Earth freezing when looking at a specific location on
the Intel Linux Graphics bug tracker which is the same kind of freeze
and it finally wasn't resolved. This problem has been hunting me since
KMS updates after upddates for months, almost a year now.
Running Kernel 2.6.30-gentoo-r5 64 bits
Xorg 1.6.3.901-r2
Mesa 7.5.1
xf86-video-intel 2.8.1
libdrm 2.4.13
I don't know if it can help but it looks like I have 2 displays on top
of each other, like panning in GIMP can cause a hang because it think
the mouse is both in a screen and another, the mouse goes crazy and I
can't pan, also Conky starts then become invisible until restart, just
like it appears and the screen under.
xrandr also causes two 2 seconds hang when typed in.
If you need more info, I'll be able to provide them on demand and
experience the video freeze at least once a week, most of the time
once a day.
Here is xrandr --verbose
