Dear all, I am so glad I can post a solution (or at least workaround) for this.
Instead of downgrading from 304.132 to the previous version 304.131, I've followed the suggestion on http://askubuntu.com/questions/845632/nvidia-304-132-driver-update-wont- boot and checked which nVidia driver version should be compatible with my graphic card at http://www.geforce.com/drivers. It came out that I should install version 340.98, which I did and subsequently were able to login into my user session again. Just why Ubuntu 16.04 LTS automatic upgrade mechanism thinks my nVidia 8600 GT graphic card should work with version 304 of these drivers is probably due to some misconfiguration bugs or similar. -- 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.
