You have been subscribed to a public bug: I have Nvidia Optimus GT415M hardware on my laptop.
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. ** Affects: xorg (Ubuntu) Importance: Low Status: Incomplete -- Cannot login with Nvidia Optimus hardware installed(Ubuntu 15.04) https://bugs.launchpad.net/bugs/1449560 You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
