I've installed the suggested updates today, as usual, and rebooted. The boot progress is pending with a black screen, and I can't even switch to console with CTRL-ALT-F1.
Well, I managed to boot in recovery mode, I installed updates via console, it did not help much.
When I continue booting, I get a console login, when I type
startx, I'll get an error:
no screens found.
Is this maybe the problem? If not, what else could I do to roll back the updates, or finding the reason?
