Bug ID: 97303 Summary: battery mode for dpm state froze Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: minor Priority: medium Component: DRM/Radeon Assignee: dri-devel@lists.freedesktop.org Reporter: ce-ce-mel@hotmail.fr
I try to use the dpm state, but when I set:
echo 'battery' > /sys/class/drm/card0/device/power_dpm_state
while on battery power, laptop freezes after a time.
I tried to add radeon.dpm=1 and (radeon.bapm=1 or radeon.bapm=0) but it does not fix. Originally, I discovered this issue using TLP (where you can find the ticket https://github.com/linrunner/TLP/issues/186).
