--- Comment #49 from Thomas DEBESSE dev@illwieckz.net --- Hey, it's awesome, the workaround Lauri Gustafsson found is working well!
I just do that at after my computer startup:
``` service 'gdm' stop
echo 'high' > '/sys/class/drm/card0/device/power_dpm_force_performance_level' echo 'performance' > '/sys/class/drm/card0/device/power_dpm_state'
service 'gdm' start ```
Then it works! I was able to run the Unigine Valley and Heaven Benchmarks for the first time wit dpm enabled, without crashing at startup, and with descent performances.
If I don't do that and keep the dpm default config, my system crashes some minutes after startup (and for sure when running on heavy benchmarks like those ones).
I own a MSI R9 390X. In the past I wrote some details on bug 93288 . I'll upload my vbios soon. There is some strings like that inside:
