libGL error: failed to open drm device: Permission denied

[Gabriel Guzman]

Hello misc@,

I noticed the following error while running chrome from the shell this
evening: 

libGL error: failed to open drm device: Permission denied
libGL error: failed to load driver: i965

Which I think means that I'm not getting accelerated X.

A search of misc archives led me to this:
https://marc.info/?l=openbsd-misc=146159057503035=2 which in turn
led to: https://marc.info/?l=openbsd-misc=145125527304834=2 

Based on the information in those threads, I checked to see what TTY I
was logged in on: 

gabe@xps:~$ env
_=/usr/bin/env
LOGNAME=gabe
WINDOWPATH=ttyC4
WINDOWID=20971533
XTERM_SHELL=/bin/ksh
HOME=/home/gabe
LC_CTYPE=en_US.UTF-8
XTERM_VERSION=XTerm/OpenBSD(330)
DISPLAY=:0
SSH_AGENT_PID=92062
GOPATH=/home/gabe
PATH=/home/gabe/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/X11R6/bin:/usr/local/bin:/usr/local/sbin:/usr/games
SSH_AUTH_SOCK=/tmp/ssh-xfkLowrabhm9/agent.77539
PS1=\[\u@\]\[\h\]:\[\w\]\$ 
TERM=screen-256color
SHELL=/bin/ksh
USER=gabe
XTERM_LOCALE=en_US.UTF-8

Seemingly WINDOWPATH=ttyC4 (but I don't really know the right way to
check this) - so I added an entry to my /etc/fbtab: 

/dev/ttyC4  0600 
/dev/console:/dev/wskbd:/dev/wskbd0:/dev/wsmouse:/dev/wsmouse0:/dev/ttyCcfg:/dev/drm0

duplicating what I saw for ttyC0.

I rebotted and confirmed that I was indeed now the owner of /dev/drm0:

gabe@xps:~$ ls -l /dev/drm*
crw---  1 gabe  wheel   87,   0 Aug 25 21:18 /dev/drm0
crw---  1 root  wheel   87,   1 Aug 25 21:18 /dev/drm1
crw---  1 root  wheel   87,   2 Aug 25 21:18 /dev/drm2
crw---  1 root  wheel   87,   3 Aug 25 21:18 /dev/drm3

Then I ran glxgears, and got the permission denied message again: 

gabe@xps:~$ glxgears  
libGL error: failed to open drm device: Permission denied
libGL error: failed to load driver: i965

And, sure enough when I rechecked /dev/drm: 

gabe@xps:~$ ls -l /dev/drm* 
crw---  1 root  wheel   87,   0 Aug 25 21:18 /dev/drm0
crw---  1 root  wheel   87,   1 Aug 25 21:18 /dev/drm1
crw---  1 root  wheel   87,   2 Aug 25 21:18 /dev/drm2
crw---  1 root  wheel   87,   3 Aug 25 21:18 /dev/drm3

I'm no longer the owner.  I'm not sure when this started, but
I don't have this issue on my 6.1 box, just on the one running current. 

Sometimes, forcing the permissions on /dev/drm0 does work:

gabe@xps:~$ doas chown gabe /dev/drm0 
doas (g...@xps.my.domain) password: 
gabe@xps:~$ glxgears
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.

But then, as soon as I exit glxgears, /dev/drm0 goes right back to being
owned by root, and the error message comes back.  

Xorg log, and dmesg below... there are some drm0 errors in the dmesg
that maybe are related?  If anyone has any ideas, I'm open to trying
them out.  If not, I'l probably do a clean install on this machine as it
has been awhile since the last one.  

Also, not sure if it's relevant, but I'm a member of the `staff` login
class on this machine

Thanks,
gabe.

Just an alias to 'ls -lh', anyhow:

crw---  1 just22  wheel   87,   0 Mar 20 08:17 /dev/drm0

(this is the "normal" condition, of course)

It was created (a long time ago!) at install time.

I noticed that the ownership of the device is "just22,just22" when I log in
from ttyC0, reset to "root,wheel" when I logout from there, set to
"just22,wheel" when logging in through xenodm. Does this make sense?

Thanks for your feedback

What version of OpenBSD are you running?

Did you modified /etc/fbtab?

What is 'll' or that command used to show permissions?

Is just22 a custom user, i.e. not created at install time?


Looking at what I have, I think for a normal install it should show you this:

[just22@poseidon]-[~]> ll /dev/drm0
crw---  1 just22  just22   87,   0 Mar 20 08:17 /dev/drm0
   

libGL error: failed to open drm device: Permission denied

[Alessandro DE LAURENZIS]

Dear misc@ readers,

I'd like to make a follow-up of an old thread [0], in the hope that someone
clarify the situation.

I normally log in X through xdm (xenodm from some weeks now) and, once there,
the ownership of /dev/drm0 is changed to my user, as expected:

[just22@poseidon]-[~]> ll /dev/drm0
crw---  1 just22  wheel   87,   0 Mar 20 08:17 /dev/drm0

But, if I switch from X to ttyC0 (Ctrl-Alt-F1), log in there and then log out,
the ownership is reset:

[just22@poseidon]-[~]> ll /dev/drm0
crw---  1 root  wheel   87,   0 Mar 20 08:17 /dev/drm0

(this behavior seems consistent with the content of /etc/fbtab, meaning
that if I do the same sequence of operations from a different virtual
terminal, ttyC1 for example, /dev/drm0 ownership is left untouched).

Of cource, when I switch back in X, I'm no more able to get access to drm
device, losing hardware acceleration for applications using it and continuosly
receiving the following error message:

libGL error: failed to open drm device: Permission denied

The only way to restore the correct condition is to logout/login (or restart
xenodm service).

I temporarely worked around the problem inhibiting the login from ttyC0 (and
so reserving it as a kind of "virtual console" for kernel messages), but I'd
like to hear your thoughts on this: is it the expected/desired behavior
or should it be fixed?

All the best

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

[Mihai Popescu]

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.

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?

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).

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/?

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).

libGL error: failed to open drm device: Permission denied

[Mihai Popescu]

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?
