I've sent an up-stream fix to Gerrit: https://chromium-review.googlesource.com/c/chromiumos/platform/minigbm/+/4263398
Fix to snap-from-source will follow. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/2004586 Title: Chromium's minigbm uses incorrect path for loading radeonsi_dri driver. Status in chromium-browser package in Ubuntu: Triaged Bug description: [NOTE] This is for the HWACC build of chromium, from snap channel latest/candidate/hwacc $ snap info chromium | grep installed installed: 107.0.5304.68-hwacc (2301) 172MB - This hwacc branch uses minigbm over the Ubuntu-supplied libgbm from Mesa origin. (Unlike the Mesa variant, the minigbm bundled by chromium can do YUV buffers, like NV12.) Regular builds of the chromium snap will not use minigbm, and thus not exhibit this behaviour! Something goes wrong with the expansion of the macro DRI_DRIVER_DIR $ strings /snap/chromium/current/usr/lib/chromium-browser/chrome | grep radeonsi_ /usr/lib64/dri/radeonsi_dri.so DRI_DRIVER_DIR/radeonsi_dri.so dlopen(radeonsi_dri.so) failed with error: The DRI_DRIVER_DIR was not properly expanded to /usr/lib/x86_64-linux- gnu here. I've also built current HEAD of chromium source code manually, and did the same test on that, and that version is unaffected: $ strings out/Default/chrome | grep radeonsi_ dlopen(radeonsi_dri.so) failed with error: /usr/lib/x86_64-linux-gnu/dri/radeonsi_dri.so /usr/lib64/dri/radeonsi_dri.so A partner found this change to third_party/minigbm/src/amdgpu.c:27 to be working: //#define DRI_PATH STRINGIZE(DRI_DRIVER_DIR/radeonsi_dri.so) #define DRI_PATH "/usr/lib/x86_64-linux-gnu/dri/radeonsi_dri.so" But it is better to understand why this expansion failed. And it is possibly fixed in later chromium releases, if not, we should look how our snap building differs from the official Linux building instructions for chromium. In any case, we should track this. OS: Ubuntu 22.10 Package: chromium Snap version: 107.0.5304.68-hwacc Channel: latest/candidate/hwacc Expectations: correctly loading driver from correct location. Actual: using incorrect location. I will follow up by testing this on a machine with an AMD GPU.
