Hi Eric, Denys Thank you for answering. I tried the following: root@beaglebone:~# gles1test1 PVR:(Error): WSEGL_CreateWindowDrawable: Couldn't set CRTC: Invalid argument [0, ] 'eglCreateWindowSurface' returned egl error 'EGL_BAD_ALLOC' (0x3003) root@beaglebone:~# gles2test1 --------------------- started --------------------- PVR:(Error): WSEGL_CreateWindowDrawable: Couldn't set CRTC: Invalid argument [0, ] 'eglCreateWindowSurface' returned egl error 'EGL_BAD_ALLOC' (0x3003) I also try other configurations, like core-image-weston. After "adjusting" mesa so it won't install gbm, weston won't boot and I still errors. here the weston output: starting with no config Loding module/usr/lib/weston/drm-backend.so output repaint windows is 7 ms maximun initilizing drm backend using /dev/dri/card0 Loading module /usr/lib/weston/gl-rendered.so ... loaded module: found gbm_pvr.so found valid GBM backend : gbm_pvr.so warning no EGL_EXT_platform_base support of specific platform; failling back to eglGetDisplay failed to choose EGL config failed to initialize egl fatal: failed to create compositor backend I think the problem is around the drm thing. I'm not an expert but: when I look at /dev/dri/*, I see 2 card ( as if there is 2 drm driver) root@beaglebone:~# ls -lsa /dev/dri/ 0 drwxr-xr-x 2 root root 120 Jan 1 1970 . 0 drwxr-xr-x 11 root root 13160 Oct 6 04:22 .. 0 crw-rw---- 1 root video 226, 0 Jan 1 1970 card0 0 crw-rw---- 1 root video 226, 1 Jan 1 1970 card1 0 crw-rw---- 1 root video 226, 64 Jan 1 1970 controlD64 0 crw-rw---- 1 root video 226, 128 Jan 1 1970 renderD128 also root@beaglebone:~# ls -lsa /sys/class/drm/card0/device/driver 0 lrwxrwxrwx 1 root root 0 Oct 6 04:31 /sys/class/drm/card0/device/driver -> ../../../../bus/platform/drivers/tilcdc root@beaglebone:~# ls -lsa /sys/class/drm/card1/device/driver 0 lrwxrwxrwx 1 root root 0 Oct 6 04:35 /sys/class/drm/card1/device/driver -> ../../../../bus/platform/drivers/pvrsrvkm 1. So it sound that there is 2 drm drivers is it normal? 2. Should I change the device three to remove tilcdc, so the only drm driver will be pvrsrvkm? 3. Is there something to do to ensure libdrm use the SGX driver?
