Created attachment 121847 [details] Xorg log As far as I understand accelmethod none should just disable 2D (glamor). The man page says: "Setting this option to none disables use of the glamor acceleration architecture. In that case, all 2D rendering is done by the CPU, but 3D and video hardware acceleration can still work." Also Xorg log seems to confirm this: [ 55521.565] (II) AMDGPU(0): [DRI2] Setup complete [ 55521.565] (II) AMDGPU(0): [DRI2] DRI driver: radeonsi [ 55521.565] (II) AMDGPU(0): [DRI2] VDPAU driver: radeonsi [ 55521.565] (II) AMDGPU(0): Front buffer pitch: 15360 bytes [ 55521.566] (==) AMDGPU(0): DRI3 disabled [ 55521.566] (==) AMDGPU(0): Backing store enabled [ 55521.566] (II) AMDGPU(0): Direct rendering enabled [ 55521.566] (II) AMDGPU(0): 2D acceleration disabled Nevertheless running glxgears produces the following error: X Error of failed request: BadDrawable (invalid Pixmap or Window parameter) Major opcode of failed request: 152 (DRI2) Minor opcode of failed request: 8 (DRI2SwapBuffers ) Resource id in failed request: 0xe00002 Serial number of failed request: 48 Current serial number in output stream: 49 With this in the Xorg log: [ 55718.984] (EE) AMDGPU(0): [DRI2] DRI2SwapBuffers: drawable has no back or front?

Using Xserver 1.18.1 + git amsgpu I don't get the fails. It's really slow, though. glxgears apparently using h/w (says synced to refresh) but 12 fps, vdpau about 1 fps.

That's because of (In reply to csaba.halasz from comment #0) > "Setting this option to none disables use of the glamor acceleration > architecture. In that case, all 2D rendering is done by the CPU, [...] "All 2D rendering" includes the copies for DRI2SwapBuffers, used for GLX buffer swaps and VDPAU presentation. Generally, this option is only intended for bringing up a 3D driver, not for normal usage. So the bad news is that fixing this problem has very low priority, but the good news is that you're not really missing anything. :)
