Hi Guillaume,

...

what is the right way to add users to video group automatically? The right way is to not do that at all :)

Really? On my desktop computer my username is in video group.

...

...

For example, we would need it to run some video tests using /dev/dri/* files.

...

ll -h /dev/dri/ total 0 crw-rw----+ 1 root video 226, 0 avril 22 16:38 card0 crw-rw---- 1 root video 226, 64 avril 22 16:38 controlD64 I think the way it should work is that logind should determine that you're a locally logged in user and do a setfacl on your device to grant you access in *addition* to those who are in group video.

in this case it seems there was no facl set, did logind think that you're locally logged in?

How to check?

Guillaume

Greetings Dirk

# grep video /etc/group video:x:33:lancelot,andrea,gdm You can edit /etc/group and add users like I did here for users lancelot,andrea. Regards Sid. -- Sid Boyce ...

It is openSUSE 12.2 and I do not remember if I added my username to videogroup.

crw-rw----+ 1 root video 226, 0 avril 22 16:38 card0 crw-rw---- 1 root video 226, 64 avril 22 16:38 controlD64 btw, you do have an ACL set, sorry that I missed that while reading the mail on the phone, see the '+' in this line:

crw-rw----+ 1 root video 226, 0 avril 22 16:38 card0

so you can do something like:

getfacl /dev/dri/card0

which should print then:

# file: dev/dri/card0 # owner: root # group: video user::rw- user:dmueller:rw-

I think your problem is that controlD64 does not have the ACL set as well. correct?

Here are the getfacl results:

getfacl dev/mali0 # file: dev/mali0 # owner: root # group: video user::rw- group::rw- other::---

getfacl dev/dri/card0 # file: dev/dri/card0 # owner: root # group: video user::rw- user:guillaume:rw- group::rw- mask::rw- other::---

getfacl dev/dri/controlD64 # file: dev/dri/controlD64 # owner: root # group: video user::rw- group::rw- other::---

So, /dev/mali0 and /dev/dri/controlD64 have not the ACL set. I guess an udev rule should do the trick. Guillaume

Greetings, Dirk
