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

    Well, 15.04 has gone End-Of-Life and is no longer supported, so it would help if you could check which version you actually installed. It should be in the "Details" section of the System Settings. –  Feb 09 '16 at 17:43

    Update your question to include the output of cat /etc/os-release as this will tell us what OS version you are running. Thank you! – Terrance Feb 09 '16 at 17:48

    As for your mouse,keyboard thing , go to older kernel , like , before 4.0, maybe 3.13 if you have that. Use usb or wireless keyboard / mouse for now – Sergiy Kolodyazhnyy Feb 09 '16 at 17:49
  • It is also inadvisable to only run an old kernel because it will not be patched with new security updates and may become incompatible with other things running on your machine. –  Feb 09 '16 at 17:52
  • @ParanoidPanda true but for the time being , we need to at least get the system working again. – Sergiy Kolodyazhnyy Feb 09 '16 at 17:54
  • @Serg: But I don't think that just stopping your kernel from updating is a good idea because then it will never receive important security updates which will lead the heightened possibility of a successful attack on the system. –  Feb 09 '16 at 18:01
  • That may be true for servers , which are constantly bombarded with botnets. With desktop users - it can wait. – Sergiy Kolodyazhnyy Feb 09 '16 at 18:04
