Okay I was able to fix this. I tried updating to nvidia-375 in case that was the issue, and during the install I noticed it was compiling something with clang instead of gcc. After that I was getting the same behaviour from both 4.4.0-72 and 4.4.0-75.
I think what happened was: 1. I did update-alternatives to switch cc/c++ to clang 2. I updated my kernel, which rebuilt part of nvidia's driver with clang 3. Broken. I fixed it by doing: 1. apt-get-purge nvidia-* 2. update-alternatives back to gcc 3. re-install nvidia-375 I'm now using nvidia-375 with kernel 4.4.0-75. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1686299 Title: Cannot get past login after update to 4.4.0.75-generic Status in linux package in Ubuntu: Incomplete Bug description: After running software update on 16.04 and rebooting, I cannot get past the login screen. The screen appears the wrong resolution and squashed smaller than the screen with a black border. When I login, it accepts the password, but after a few seconds the screen gets corrupted then resets back to the login screen. Rebooting to an older kernel fixed the issue.
