Same with my Dell E6520 with HD3000 and NVS4200M. When I switch to Nvidia I am stuck in a black screen just before the login screen.
The strange thing is that when I connect an external monitor through VGA port I can login and use the desktop on the external monitor but built- in display is still blank. Each time I have to drop back to console and switch back to intel with prime-select command. to get the screen back. Just after switching to Nvidia xorg.conf is deleted and if I copy a previously backed-up xorg.conf file Nvidia works but is broken again when I make a switch from Intel to Nvidia. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1362848 Title: ubuntu 14.04 after install nvidia binary driver 331.89 black screen and freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-331/+bug/1362848/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
