Same problem for me. Temporarily workaround is to only use intel card by selecting it through prime-select. This requires that you have installed nvidia-prime:
- Get tty1 by pressing CTRL-ALT+F1 - Login with user with sudo rights - Switch to intel card: "sudo prime-select intel" - Restart lightdm: "sudo systemctl restart lightdm.service" Hope this helps until this bug gets fixed. -- 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
