It seems like the kernel and the nvidia driver weren't built using the same compiler.
Please, either ssh into your machine, or press CTRL+ALT+F2 and do the following: 1) Make sure security updates are enabled, and update your system ("apt- cache policy gcc-5" should report 5.4.0-6ubuntu1~16.04.9 on Xenial) 2) Make sure no driver from NVIDIA's website is installed. If it is, please uninstall it first. 3) When gcc-5 is updated, re-install the nvidia package from the archive: sudo apt-get install --reinstall nvidia-384 (or nvidia-340) 4) Restart your computer. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1750937 Title: 4.4.0-116 Kernel update on 2/21 breaks Nvidia drivers (on 14.04 and 16.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1750937/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
