Cannot access secondary GPU: [drm] failed to set drm interface version: Permission denied

[timfayz]

I have the common issue. When I try to run something through optirun, I get the following:

[13395.278406] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) intel(0): [drm] failed to set drm interface version: Permission denied [13].
[13395.278522] [ERROR]Aborting because fallback start is disabled.

Specification:

• Ubuntu 14.04
• NVIDIA Corporation GF108M [GeForce GT 630M](rev a1)
• Nvidia 331 driver

I've tried to reinstall nvidia and bumblebee packages, to remove something related with nvidia within /usr/share/X11/xorg.conf.d, uncomment BudID in the xorg.conf.nvidia file

What is wrong?

Yep, I get the same with nvidia-304.

Also running 14.04 but with a GeForce GT 620M and the xorg-edgers ppa.

[circlingthesun]

So I've purged the xorg-edgers ppa, no luck. Then purged the bumblebee ppa and reverted to the ubuntu packaged version, nope. I then removed all bumblebee settings and reinstalled it, with the ubuntu package and then with the bumblebee ppa, still no luck. Now I'm reinstalling xorg-edgers. Does anyone have idea what might cause this issue?

[jkwong888]

I was having this problem too. For me, it was loading the default system config directory, see /var/log/Xorg.8.log:

[  3193.759] (++) Using config file: "/etc/bumblebee/xorg.conf.nvidia"
[  3193.759] (++) Using config directory: "/etc/bumblebee/xorg.conf.d"
[  3193.759] (==) Using system config directory "/usr/share/X11/xorg.conf.d"

xorg.conf.d contains 20-intel.conf which contains the intel card definition. But it seems the order of loading these devices was messed up and xorg attempted to load the intel card first before the nvidia card. since intel is already used by display :0 it barfs with the drm error.

I got around this by appending "Screen" section to /etc/bumblebee/xorg.conf.nvidia and force it to use the "DiscreteNvidia" device as defined at the top of this config file:

Section "Screen"
    Identifier "Default Screen"
    Device "DiscreteNvidia"
EndSection

[jgolinowski]

I ran into this error today after a minor update of xserver-xorg-core and xserver-common. I'm glad I quickly found this workaround here because it works like a charm :)

[zekefast]

Have same error on Debian Jessie.
I tried to add Screen section as @jkwong888 suggested, but it did not helped.

Is there anybody who knows how to fix or wordaround the issue?

Thank you in advance!

P.S.:
Video: Nvidia GeForce GT 650M

[NicolaeGrigoriu]

Had the same error, on clean install on the ubuntu 14.04, Nvidia GeFroce GT 630 M and @jkwong888's advice have helped me. Thank you.

[arashtarafar]

Thanks, @jkwong888 ! Worked perfectly!

Thanks @jkwong888! It worked for me too.

I have the same bug on Debian/Jessie, using bumblebee 3.2.1 and primus 20140711.

$ lspci -vnn | grep '\''[030[02]\]'
00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller])
01:00.0 3D controller [0302]: NVIDIA Corporation GM107M [GeForce GTX 860M] [10de:1392] (rev ff) (prog-if ff)

When running optirun, I see the following in dmesg:

[ 1536.341360] bbswitch: enabling discrete graphics

@jkwong888's suggestion didn't help.

@theocrite I've reported the bug days ago into libdrm-intel1, but it seems linked to bumblebee:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=768045

Unfortunately, i don't know how to link bug to another package in debian bug report system.
