I have tried Aaron's patches myself and they do make the "Failed to claim DRM device." error messages in /var/log/Xorg.0.log disappear and the log looks like the NVIDIA driver is working fine, but I still boot to a black screen.
So there is either another problem, or those patches don't quite fix this issue. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1449560 Title: Cannot login with Nvidia Optimus hardware installed(Ubuntu 15.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1449560/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
