kevin64 graphics issues |
||||||||||||||||||||||||
Issue description(Spltting this from the main bug to make it easier to discuss) I built a kevin64 image using the latest Chrome OS sources which also had VIDEO_CARDS=rockchip. However, login screen still fails to come up. I have disabled the sandbox as suggested: https://bugs.chromium.org/p/chromium/issues/detail?id=878565#c20 "--disable-gpu-sandbox --no-sandbox" As p[er the logs in /var/logs/ui: The failure is in loading the libGLESv2.so.2 library. device-enumerator: scan all dirs device-enumerator: scanning /sys/bus device-enumerator: scanning /sys/class [15782:15782:0907/155429.843324:ERROR:egl_util.cc(59)] Failed to load GLES library: libGLESv2.so.2: cannot open shared object file: Operation not permitted I am sure that I have the library in /usr/lib64: # ls /usr/lib64/libGLESv* -lt lrwxrwxrwx 1 root root 22 Sep 7 15:29 /usr/lib64/libGLESv1_CM.so.1 -> libGLESv1_CM.so.1.1.20 lrwxrwxrwx 1 root root 19 Sep 7 15:29 /usr/lib64/libGLESv2.so -> libGLESv2.so.2.1.20 lrwxrwxrwx 1 root root 19 Sep 7 15:29 /usr/lib64/libGLESv2.so.2 -> libGLESv2.so.2.1.20 lrwxrwxrwx 1 root root 22 Sep 7 15:29 /usr/lib64/libGLESv1_CM.so -> libGLESv1_CM.so.1.1.20 lrwxrwxrwx 1 root root 17 Sep 7 15:29 /usr/lib64/libGLESv1_CM.so.1.1.20 -> libmali.so.0.1.20 lrwxrwxrwx 1 root root 17 Sep 7 15:29 /usr/lib64/libGLESv2.so.2.1.20 -> libmali.so.0.1.20 Same error is reported in /var/log/chrome/ [19915:19915:0907/155519.384285:ERROR:egl_util.cc(59)] Failed to load GLES library: libGLESv2.so.2: cannot open shared object file: Operation not permitted [19380:19390:0907/155520.311714:WARNING:drm_device_handle.cc(83)] Failed to authenticate /dev/dri/card1 within 1000 ms [19380:19380:0907/160118.800237:VERBOSE1:component_updater_service.cc(322)] CheckForUpdates: automatic updatecheck for components.

Just to make sure, how exactly did you edit chrome-dev.conf? You should add the arguments without quotation marks, and on separate lines, like this: --disable-gpu-sandbox --no-sandbox Sorry if that wasn't clear. This worked for me so far, but I'm also looking for a permanent solution to this problem.

Thanks Daniel, I believe my issue was an incremental build (probably drivers were not built correctly). After a full clean build, and with the sandbox + gpu sandbox disabled, the login screen finally came up :-).

I've been trying to figure out the cause of this problem, but so far I haven't been able to get to the bottom of it. The issue is that the sandbox seccomp blocks the newfstatat and openat syscalls, but both of them are allowed in the seccomp policy that is in use, and I'm not sure what's going wrong here. Until this is resolved, I've submitted a CL which disables the sandbox early initialization, so editing chrome-dev.conf won't be necessary any more. https://chromium-review.googlesource.com/c/chromiumos/overlays/board-overlays/+/1224273
