With or without LIBGL_DRI3_ENABLE=3D1 in the environment the result is
the same. I use official packages, updated yesterday.

The problem I face might be due to permission issue. ktrace shows this:
28047 eglinfo  CALL  openat(AT_FDCWD,0x7fffffffc820,0x100002<O_RDWR|O_CLOEX=
EC>)
28047 eglinfo  NAMI  "/dev/dri/card0"
28047 eglinfo  RET   openat 3
/..../
28047 eglinfo  CALL  ioctl(0x3,0xc0106446,0x7fffffffbc70)
28047 eglinfo  RET   ioctl -1 errno 13 Permission denied

ls -l /dev/dri/card0
lrwxr-xr-x  1 root  wheel  8 20 avr.  13:52 /dev/dri/card0@ -> ../drm/0

ls -l /dev/drm/0
crw-rw----  1 root  video  0x83 20 avr.  13:08 /dev/drm/0

I am in both wheel and video group, and X11 is working just fine. Any
additional config is necessary?

Thanks
