Does the attached patch help? Alex Yes, it helped, thank you very much. The compressed Xorg.0.log is attached as proof. To others: the patch is against xf86-video-ati. Two notes, though: 1. Is it normal that "xrandr --listproviders" lists 3 providers? [zozo at localhost ~]$ cat xrandr-providers Providers: number : 3 Provider 0: id: 0x86 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 4 outputs: 3 associated providers: 2 name:radeon Provider 1: id: 0x4f cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 0 outputs: 0 associated providers: 2 name:radeon Provider 2: id: 0x4f cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 0 outputs: 0 associated providers: 2 name:radeon 2. I tried glxgears with and without DRIPRIME=1 as below: [zozo at localhost ~]$ glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 299 frames in 5.0 seconds = 59.558 FPS [zozo at localhost ~]$ DRIPRIME=1 glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 5589 frames in 5.0 seconds = 1117.730 FPS 5369 frames in 5.0 seconds = 1073.715 FPS 5699 frames in 5.0 seconds = 1139.670 FPS Obviously, it doesn't sync to the framerate with PRIME. On the other hand, nothing is displayed in the glxgears window. I have llvm 3.4-4 and Mesa 10.1-rc1 from Fedora 21 rawhide.

Make sure you are running a compositor.
