I have Ubuntu 18.04 running in a dual boot setup along with Windows 8.1 From the past 3 days, Ubuntu has become completely unusable on my laptop because it keeps freezing randomly after some time. I already had network issues with Ubuntu wherein my Wifi would randomly disconnect after some time and my Wifi connection would become invisible. I sometimes had to turn off my Wifi for 5-10 minutes and then it would reconnect and the internet would work.


Till yesterday, I was getting some errors related to inodes on a black screen during startup. I have posted images of those messages. Also, when my laptop froze, I was ableto restart it by pressing Alt + Sys Rq + reisub, but today even this has stopped working. I have to turn it off using the power button on the laptop and then turn it back again.


Havent installed any new programs recently, just an update about 4-5 days ago.

Heres the output of cat /var/log/syslog from around the time when Ubuntu froze:
