libGL error: failed to open drm device: Permission denied

Mihai Popescu-3
Hello,

I am running cwm and I had some problems starting chrome from the menu
- it starts for the very first time when i click on the menu, then i
have to click 2 or 3 times on menu entry to start chrome again. This
is not a big deal, maybe a cwm glitch.

I went to start chrome from xterm, and I got these errors:

$ chrome
libGL error: failed to open drm device: Permission denied
libGL error: failed to load driver: r600
libGL error: failed to open drm device: Permission denied
libGL error: failed to load driver: r600

Is it normal, can it be fixed on my side?

The ownership of /dev/drm0 should be changed according to
/etc/fbtab to your user after logging in.

Can you include the output of ls -l /dev/drm0 and
the contents of /var/log/Xorg.0.log ?

How are you starting X, xdm/startx/?

Quick and dirty hack around this (if your user is in group wheel):

$ grep chmod .xinitrc
sudo chmod g+rw /dev/drm0

$ ls -l /dev/drm*

Any other suggestions, and moreover proper way to address this?

I have noticed (in the past), switching from X to virtual term
(Ctrl+Shift+Fx) will override/revert the ownership of /dev/drm0,
resulting in above (or similar) errors when I switch back to X
and run something like xlock.

I say "in the past", as I have avoided above switching since.

Hope this sheds some light onto the problem (or possibly
as-designed behavior).

Re: libGL error: failed to open drm device: Permission denied

In reply to this post by Mihai Popescu-3
Well, things were sorted out.

Looking at that /etc/fbtab file Jonathan Gray pointed out (and yes,
this is not a typo of /etc/fstab like I thought before) I can spot the
/dev/drm0 in that long list of devices prepared for chown at login.

But, that file is filled in for ttyC0 only, the tty that most users
are using it for login. But, giving the fact that I got some annoying
kernel messages from my connecting/disconnecting USB mouse with
aggresive power management routines, I was using ttyC1 for login. From
that things got another way. I think this clarifies the other issue of
changing tty / ownership change mentioned in this thread by somebody
else.

So the error was not really an error, going back to ttyC0 login I got
the right permission and the messages are no more. Of course I can
edit the /etc/fbtab, too.

One question please: is it right that not getting access to /dev/drm0
is like losing hardware acceleration for applications using it?

Thanks.

Similar here, not using anywhere ttyC0, rather tty00 and ttyC1 to
ttyC5.  Confirmed the /etc/fbtab lines for these ttys worked as
expected in these cases.

Interesting if you ssh log in to startx, e.g. ttyp0, does this work
in /etc/fbtab and is it expected to in this case?

Yes, on a drm(4) supported device.  You could confirm this with the
demo glxgears(1).
