Trying to setup Optimus with Nouveau

English Install/Boot/Login
1

Dear Community,

some time ago I switched to Tumbleweed (on my Optimus-laptop). Since it is much less hassle (and also more trustworthy imo) I decided to stick with nouveau for 3D support. I installed bumblebee and edited bumblebee.conf to use nouveau as driver. After I start the OS I can run optirun --status which tells me that the discrete graphics card is disabled. If I then try

optirun glxspheres

I get:

1947.553656] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) /dev/dri/card1: failed to set DRM interface version 1.4: Permission denied

1947.553705] [ERROR]Aborting because fallback start is disabled.

Note that my user account is in the video and bumblebee groups.

I hope that anyone here can help me with this.

Best regards

And what are permissions and ACLs of /dev/dri/card1?

Can you explain how to find that out?

ls -lL /dev/dri/card1
getfacl /dev/dri/card1

Thanks

ls -lL /dev/dri/card1:

crw-rw----+ 1 root video 226, 1 17. Jan 15:55 /dev/dri/card1

getfacl /dev/dri/card1:

    getfacl: Entferne führende '/' von absoluten Pfadnamen

file: dev/dri/card1

owner: root

group: video

user::rw-
user:$USER:rw-
group::rw-
mask::rw-
other::—

(I replaced my username by $USER…)

This one sounds very similar and problem was leftover libraries from nVidia driver. Did you remove it when swithing to nouveau?

No, but I’m using a fresh Tumbleweed install…

Full Xorg.0.log would be useful. Please upload it to http://susepaste.org
