Public bug reported:
After updating to linux-image-4.15.0-177-generic, my machine completely
freezes on the Ubuntu Welcome screen, i.e. right after switching to GUI
mode. The mouse pointer is frozen, the keyboard does not even respond to
CAPS LOCK or NUM LOCK, pressing CTRL+ALT+F2 shows no reaction.
I cannot work with my machine at this point and have to hard reset it.
Selecting advanced boot options in grub and selecting the previous linux
kernel 4.15.0-176 makes it work again. So this bad bug was introduced
with the 4.15.0-177 kernel release.
I tried removing the nvidia-driver-510 package, presumably making Ubuntu
use the "nouveau" driver, and with that, I could use the welcome screen
and log in, but the machine still froze shortly afterwards.
So maybe this is some sort of interference with my GeForce 1080 graphics
card, but it is not specific to the driver used.
