I am using Ubuntu MATE 16.04, which is freezing up, meaning, I can’t move the mouse, switch to console or programs with alt + tab, even a press on the power button doesn’t initiate a shutdown. All I can do is do a hard shutdown.
I have seen this thread: Upgrade to 16.04 xenial is periodically freezing
However I don’t quite know my way around Ubuntu and Linux and am afraid to use fixes for my system which is different from that in that thread. I am able to use terminal, but I have no idea about the structure of linux and can’t read those logs. However I saw at the time of the crash in /var/log/syslog a long entry with /00/00/… over several (about 10) lines.
I can also gerenate the freeze by unplugging or plugging the power cord back in. Also closing and opening the lid again will trigger the freeze. Which makes me think it is related to the power management, which I uninstalled but the problem remained.
I also did a reinstall of Ubuntu to no success.
