When I change my nvidia graphic card drivers from nouveau to the closed source, tested driver, everything works fine.
Right after a reboot I do not get past the LUKS auth screen. The window stays purple. TTYs are not loaded yet, and I cannot look at the terminal.
What should I do now to return to normal usage of Ubuntu WITH nvidia drivers, not nouveau?
I solved this problem just recently, by adding the kernel command-line parameter "nouveau.modeset=0" in /etc/default/grub and running update-grub.
Of course, if you plan to use nouveau for anything, this might not be a good solution for you. But, personally, I don't care about nouveau at all.
This has helped:
Installing nvidia-370 seems to fix a lot, but theres a bug. This solution worked for me: https://askubuntu.com/a/843534/600016
Now I just need to use the recovery image and just straight resume everytime, otherwise it'll stop loading at the initial ramdisk-bootloader.
