Summary: [RV770] System hangs when display goes in sleep mode (with mid profile setting) Product: DRI Version: XOrg CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: b.bellec@gmail.com
I set my Radeon in mid profile mod most of the time. After 10 minutes of inactivity, my display goes in sleep mode. Then I cannot resume the computer. I need to hard reboot. Even SysReq isn't helpful.
