I've upgraded my Ubuntu 14.10 where everything was working fine with Nvidia Optimus to Ubuntu 15.04 and now I cannot login. After I type the password login screen comes back again. I did complete reinstall of NVidia packages and installed new nvidia-346 package from Ubuntu repo. Looking at Xorg.0.log I see this message: [ 120.353] (EE) intel(G1): [drm] failed to set drm interface version: Permission denied [13]. [ 120.353] (II) intel(G1): [drm] Contents of '/sys/kernel/debug/dri/0/clients': [ 120.353] (II) intel(G1): [drm] a dev pid uid magic [ 120.354] (II) intel(G1): [drm] [ 120.354] (II) intel(G1): [drm] y 0 2996 0 0 [ 120.354] (II) intel(G1): [drm] y 0 2996 0 0 [ 120.354] (EE) intel(G1): Failed to claim DRM device. And I have found thread regarding this problem on https://devtalk.nvidia.com/default/topic/816599/prime-switching-to- nvidia-creates-black-screen/. So looks like hardware similar to mine need a new version of xserver-xorg-video-intel. Could you please help with this.
