Package: bumblebee
Version: 3.2.1-7
Followup-For: Bug #756522
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
* What exactly did you do (or not do) that was effective (or
ineffective)?
Run a command to launch an application with the optirun command, for
example "optirun glxgear -info" After getting the above mentioned
message I searched online for a solution of this bug. I tried to
add to the /etc/bumblebee/xorg.conf.nouveau an additional "Screen"
Section, as this solution worked for some people with Ubuntu
systems. It didn't work for me. The lines I added to this file are:
Section "Screen"
Identifier "Default Screen"
Device "DiscreteNvidia"
EndSection
* What was the outcome of this action?
The outcome was the same as before and the same as reported by other users detecting this
bug:
[ERROR] Cannot access secondary GPU - error: [Xorg] (EE)
/dev/dri/card0: failed to set DRM interfaces version 1.4: Permission
denied
[ERROR] Aborting because fallback start is disabvled.
* What outcome did you expect instead?
That the application starts using the DiscreteNvidia Card.
