Bug#679312: xserver-xorg-video-radeon: Rotation fails due to Acceleration init failed, but DRI works nevertheless

OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x209) llvmpipe is software rendering, not hardware acceleration. This wouldn't be all that bad, if I could still rotate my displays via XRandR, but this fails, too: ~ ◆ xrandr --output HDMI-0 --rotate right xrandr: Configure crtc 0 failed Same reason: Rotation requires acceleration. DRM Information from dmesg: --- [0.00] No AGP bridge found [0.00] No AGP bridge found [0.463471] Linux agpgart interface v0.103 Looks like something is preventing the radeon kernel driver from loading / initializing. Is it built into the kernel or as a module? If the latter, what happens if you try to run 'sudo modprobe radeon' from console (ideally before X starts)? -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Debian, X and DRI developer -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

The log that was auto-attached was actually the log without rotation, not that it mattered greatly :-) OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x209) llvmpipe is software rendering, not hardware acceleration. Ah, that explains a lot! Somehow my brain was hard-wired into associating lack of acceleration with the MESA software driver, I haven't been using the open source radeon driver for a long time :-) DRM Information from dmesg: --- [0.00] No AGP bridge found [0.00] No AGP bridge found [0.463471] Linux agpgart interface v0.103 Looks like something is preventing the radeon kernel driver from loading / initializing. Is it built into the kernel or as a module? If the latter, what happens if you try to run 'sudo modprobe radeon' from console (ideally before X starts)? That did the trick! Turns out the radeon module was not loaded at boot-time, probably it was not in the initrd. Loading the module and starting X.org with rotation enabled works now, as does XRandR. Sorry for opening a silly bug like this, but maybe this could be considered a real-world use-case for more explicit error messages ;-) Thank you!
