I found the culprit to this issue for me anyway, do not install the upgrade package for sudo add-apt-repository ppa:xorg-edgers/ppa -y you can upgrade everything else. But upgrading after adding that repository will cause the login loop.
for working nvidia drivers i did this. reinstalled ubuntu 15.04 i went ahead and installed my plug-ins (flash, Java etc.) Open Terminal Sudo apt-get update Sudo apt-get upgrade after upgrading use sudo add-apt-repository ppa:xorg-edgers/ppa -y then install nvidia drivers i used: sudo apt-get install nvidia-352 and have working drivers. Do not run another upgrade with sudo add-apt-repository ppa:xorg- edgers/ppa -y checked. Instead go into Software & Updates and uncheck the repository under Other Software: http://ppa.launchpad.net/xorg- edgers/ppa/ubuntu vivid Then all should be good! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1432004 Title: Nvidia broken after update on 15.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/steam/+bug/1432004/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
