It really seems to be related to drm for i915 driver when switching to
nvidia via prime-select and login via lightdm. The Xorg.0.log shows an
error like:
[25.199] (EE) intel(G1): [drm] failed to set drm interface version:
Permission denied [13].
[25.199] (II) intel(G1): [drm] Contents of
Same problem for me. Temporarily workaround is to only use intel card by
selecting it through prime-select. This requires that you have installed
nvidia-prime:
- Get tty1 by pressing CTRL-ALT+F1
- Login with user with sudo rights
- Switch to intel card: "sudo prime-select intel"
- Restart light
I reinstalled my laptop with wily (15.10) while hoping kernel 4.2.0.7
could fix the problem. I got a step forward. The drm related error is
gone, but a seg fault rises up in Xorg.log and I ended up in a black
screen when switching to nvidia:
[ 1704.596] (EE) intel(G0): failed to set mode: Permiss

Yesterday I installed nvidia driver 355.11 update from the "ubuntu fresh

In the case of the reported ASUS laptop it could be a problem related to the
BIOS version, but not in my case. And truely not in the case of a lot of other
users.

Sorry being late, I had not much time the last days.
I tried following previous versions with NO SUCCESS:
- nvidia-340.93
There's only one last official version in official repos I didnt't try:
- nvidia-304.128
But this is not worth trying because it has no prime support.
Thank you for helping.
