I experienced the same issue as Marcin described after updating from 14.10 on my Thinkpad T420.
In order to solve it I had to manually remove all nvidia-* packages and install nvidia-346. Not a big deal for anyone somehow comfortable with a shell but probably a show stopper for some other users. Is there any mechanism to force using nvidia-346 when performing a distribution upgrade? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1428328 Title: nvidia-prime needs sddm support To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1428328/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
