(In reply to Brian Paterni from comment #0) > > [ 170.017] (EE) 3: /usr/lib/x86_64-linux-gnu/libLLVM-3.8.so.1 [...] > [ 170.018] (EE) 4: /usr/lib/x86_64-linux-gnu/libLLVM-3.5.so.1 [...] Looks like both 3.8 and 3.5 versions of LLVM are getting pulled in, and LLVM 3.5 wasn't safe against this yet. Is your self-built radeonsi_dri.so available in /usr/lib/x86_64-linux-gnu/dri/ as well? That's where the Xorg glx module looks for the DRI drivers. I suspect it's failing to load radeonsi_dri.so from there and falling back to swrast_dri.so, which is linked against LLVM 3.5. I think you're right, Michel! The self-built radeonsi_dri.so is actually installed to /usr/local/lib/dri, and I'm relying on LD_LIBRARY_PATH/LIBGL_DRIVERS_PATH to hopefully pick up the local libraries. As soon as I backup the debian-provided /usr/lib/x86_64-linux-gnu/dri/radeonsi_dri.so and overwrite with the local radeonsi_dri.so, startx works once again! Not only that, but hardware acceleration seems to run much faster than my previous working compile! No more slow redraws when I swap windows across screens, YAY! Thank You, Michel! :) Glad it's working again, resolving as a setup issue. |

Created attachment 118864 [details] failing Xorg.0.log -- non-root X X had been working fine (aside from performance) using compiled-from-source xf86-video-amdgpu and mesa. This morning, however, I was greeted with a segfault upon startx. The only thing that seems to have changed though, is an upgrade to debian's xserver-xorg packages which look to have introduced non-root X. Would this be the cause of the following segfault cut from the attached Xorg.0.log? I do have the xserver-xorg-legacy wrapper installed, but startx still fails (unsure if additional configuration might be needed for xserverxorg-legacy?) Please let me know if additional information is needed. I have xserver-xorg-core-dbg debugging symbols installed, but some locations in the backtrace are not resolved...
