https://bugs.freedesktop.org/show_bug.cgi?id=75992 --- Comment #30 from Egon Ashrafinia --- "echo "high" > /sys/class/drm/card0/device/power_profile" crashes me too when I try to set it after "radeon.dpm=0". Because the default one is really on a low level. No OpenGL animation works smooth. My hole Display turned black, but the computer was still turned on. ... No reactions anymore. Hard Restart required. -- You are receiving this mail because: You are the assignee for the bug.
