Recently I've moved to Ubuntu 20.04 LTS and for the first two months everything was amazing and I could do everything as much as I want but from about a month ago a new problem had come on the board.
The problem was when I leave the OS works for more than 6 hours at the first the 6 hours was 12 hours but now that is the deal ... whatever after 6 hours of working the gnome-shell start crashes (how did I know ?! I had seen it in the system monitor rising CPU usage from maybe 20% to 100% one core each time and for approximately one second every since and then ) and that is annoying because that affects other processes and make kind of interruption.
I don't know why but since that happens I start asking and searching for the reason and I found nothing then I decided to try using another desktop environment like KDE but that may cause other problems like how I found then I found someone talking about window manager and yeah I tried i3-WM and yeah the problem disappeared but new problems had appeared.
Now when I restart the system ... firstly it takes too long to start the system and then it shows messages that I didn't understand (in the image down the script) and everything goes harder and takes too much time to open or run even terminal or file manager ... I don't know what to do.
I'll appreciate your help.
