yesterday i installed some updates with the automatic ubuntu updater and shutdown my pc after that.
now i try to reboot and i now have the problem that my mouse and keyboard aren't recognized (not responding) anymore. besides that, the monitor has a very low resolution.
i have installed ubuntu 15.04 or 15.10, i cant remember exactly.
i already tried to remove all harddrives etc.
any help?
UPDATE 1
- now i started the pc with holding shift and started with a older kernel (4.2.23-generic). it is running now as before.
- but how can i revert the update?
UPDATE 2
- i now changed grub in that way, that it is automatically starting with the last kernel i found running (4.2.23-generic)
- to do that i followed the instructions in this link
- another link explaining how to change grub
