Bug ID: 65811 Summary: AMD 7970M (PowerXpress) power management not functioning properly when using Xrandr to offload rendering Product: Drivers Version: 2.5 Kernel Version: 3.13-rc1 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri at kernel-bugs.osdl.org Reporter: jack at cyphernaut.org Regression: No rc1 appears to have solved my issues of X not starting or crashing when starting, which I ran into when using the DRM patches on 3.12. However I've run into another issue: When I start my laptop, if I do not immediately offload rendering to the discrete Radeon card (xrandr --setprovideroffloadsink radeon Intel) the state in vgaswitcheroo will change to 'DynOff', and xrandr --listproviders will no longer report the radeon as a potentially offload source Conversely, if I *do* --setprovideroffloadsink to the radeon within a few seconds after X starts, the state in vgaswitcheroo changes to DynPwr and never actually turns off (laptop behaves as if runpm was not enabled at all). -- You are receiving this mail because: You are watching the assignee of the bug.
