Yup, thats the problem.
Booting into systemd gives this:
one:~# ll /dev/dri*
total 0
crw-rw----+ 1 root video 226, 0 2011.09.07 15:12 card0
crw-rw-rw- 1 root video 226, 64 2011.09.07 15:12 controlD64
one:~# getfacl /dev/dri/card0
getfacl: Removing leading '/' from absolute path names
# file: dev/dri/card0
# owner: root
# group: video
user::rw-
user:gdm:rw-
group::rw-
mask::rw-
other::---
But with init, card0 has no acl.
As a quick hack,
one:/dev/dri# service dm stop
Stopping display manager: [ OK ]
one:/dev/dri# chmod 666 card0
one:/dev/dri# ll
total 0
crw-rw-rw- 1 root video 226, 0 2011.09.07 19:15 card0
crw-rw-rw- 1 root video 226, 64 2011.09.07 19:15 controlD64
one:/dev/dri# service dm start
Starting display manager: [ OK ]
one:/dev/dri#
made it work!
