The patch runs stable for me so far. But I hit the suspend/resume issue again.
When I ssh into the machine, I get through xrandr
rd@blackbox:~$ xrandr -display :0
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 8192 x 8192
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm
x 301mm
1280x1024 60.0*+
1024x768 60.0
800x600 60.3
640x480 60.0
720x400 70.1
rd@blackbox:~$
which looks ok fo me. I tried to switch to another resolution, but the machine
autosuspended, before I was able to do so (I took me a few minutes to figure
out a copy and paste problem :-( ). After the second resume, HDMI was working
again.
xrandr shows the same data after the second resume:
rd@blackbox:~$ xrandr -display :0
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 8192 x 8192
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm
x 301mm
1280x1024 60.0*+
1024x768 60.0
800x600 60.3
640x480 60.0
720x400 70.1
rd@blackbox:~$
Are there any other data I could gather to figure out what is going wrong?
Thanks,
Rainer
BTW, I start thinking on workarounds. One workaround would be to immediately
suspend the system again, when I hit the problem. Since only graphics seems to
be affected, I am thinking of "blindly" switching to a VT enter the root
password and run pm-suspend. What I am worried about is that I have to enter
the root password blindly. Are there better ways to manually suspend (without
booting up another system and sshing in)? Could a cron script (e.g. running
once a minute) detect the situation (but how, xrandr output seems to be ok)?
Many thanks,
Rainer
