Okay, I'm in. I replace the window manager installing compiz and now I can login with nvidia 304.
Steps: - Install compiz - Add "compiz --replace" to autostart - Install nvidia-304 - Reboot Result: In first login, I have a loop and in the second time that I enter password, I am enable to login. Notes: This confirms that is an incompatibility with budgie window manager and nvidia 304. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1675830 Title: nvidia 304 graphics causes Login loop in Ubuntu Budgie To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntubudgie/+bug/1675830/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
