--- Comment #83 from Thomas DEBESSE dev@illwieckz.net --- (In reply to Ioannis Panagiotopoulos from comment #82)
the environment was still slow, despite the Xorg.log stating that acceleration was on.
Yeah, that was a "low" profile, so it was expected to be slow… You can do that to get a "high" profile:
echo 'high' > '/sys/class/drm/card0/device/power_dpm_force_performance_level' echo 'performance' > '/sys/class/drm/card0/device/power_dpm_state'
But by the way:
The successful starts did not last very long however, as they crashed after 1-2 minutes.
If you still get a hang using a profile different than "auto" it looks like you are facing an issue I never got myself… It means the bug is wider than expected, it's not a good news. I can't help more at this point, I hope someone else will have an answer.
