To all those who could hardly await a fix: Since it is closed source driver, this issue has to be resolved upstream. So far, Nvidia has not provided an update, although (according to Aaron Plattner) they are working on it [1]. Just downgrading isn't always preferable, either. Last update was supposed to fix a security problem so you will leave your system vulnerable by rolling back to an earlier version. Waiting for upstream seems to be the only reasonable choice.
You have several options, though: * temporarily(?) switch to nouveau * use a non-composited desktop (some apps will fail but you can login) * replace the card (304 driver series is going to be discontinued anyway) [1] http://goo.gl/2RQUjB -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-304 in Ubuntu. https://bugs.launchpad.net/bugs/1639180 Title: no login possible after update to nvidia 304.132 Status in nvidia-graphics-drivers-304 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-legacy-304xx package in Debian: Confirmed Bug description: Ubuntu 16.04 LTS NVIDIA driver: - nvidia-graphics-drivers-304 - update to version 304.132 dpkg.log: upgrade nvidia-304-updates:amd64 304.131-0ubuntu3 304.132-0ubuntu0.16.04.2 - reboot - lightdm login screen - login - a few seconds some flickering - and the lightdm login screen appears again It is not possible to login.
