Xorg is starting fine with GPU support. X11 GPU test programs (e.g. tiger) are working fine. Then I built a plain Chromium 57 and copied it on top of this Yocto build. chrome://gpu shows that the GPU and WebGL are available, but in the log I see: drmOpenDevice: open result is 90, (OK) drmOpenByBusid: drmOpenMinor returns 90 drmOpenByBusid: drmGetBusid reports platform:Vivante GCCore:00 [20500:20522:0731/143818.506168:ERROR:simple_backend_impl.cc(137)] Failed to create directory: /mnt/sd/.cache/Default/Cache [20500:20522:0731/143818.506328:ERROR:simple_backend_impl.cc(585)] Simple Cache Backend: wrong file structure on disk: /mnt/sd/.cache/Default/Cache [20500:20523:0731/143818.507012:ERROR:cache_util.cc(134)] Unable to move cache folder /mnt/sd/.cache/Default/Cache to /mnt/sd/.cache/Default/old_Cache_000 [20500:20523:0731/143818.507130:ERROR:cache_creator.cc(133)] Unable to create cache [ 1] libGAL: Performing a software resolve!
