Can confirm the problem: started to occur after the update to kernel 4.4.0-45 and nvidia 367.57 and it is the combination of kernel version and nvidia-driver that causes the problem. There are no problems when the nvidia-driver is purged and nouveau is used instead. I am using full disk description.
Last working kernel with nvidia 367.57 is 4.4.0-43. Kernel 4.4.0-47 does not fix the problem. Symptoms are either a black screen with blinking underline-prompt in the topleft corner (no fde password prompt, no possibility to switch to console) or a low-res graphical screen for fde password entry, but no way to actually type the password. Setting GRUB_CMDLINE_LINUX_DEFAULT="nomodeset" works for me (it is important to remove "quiet splash" if "nomodeset" is inserted into an existing line) – with this setting, the fde password can be entered in the console and the system boots normally with nvidia 367.57 and kernels 4.4.0-45 and 4.4.-0-47. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1638990 Title: nvidia-367 with kernel 4.4.0-45-generic won't boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1638990/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
