    How much swap space do you have? free -h Read man mkswap;man swapon and create some swap space - it looks like RAM exhaustion. – waltinator May 23 at 22:36

    Edit your question and show me free -h and sysctl vm.swappiness and ls -al ~/.local/share/gnome-shell/extensions and ls -al /usr/share/gnome-shell/extensions. Start comments to me with @heynnema or I'll miss them. – heynnema May 23 at 23:30
  • actually i feel its chrome that is causing the problem... never experienced freezing since i uninstalled it @heynnema – Codesam May 30 at 11:40
  • Chrome may just be a symptom, not really the cause. If you show me the info I requested, we might get a different perspective on your problem. – heynnema May 30 at 15:26

I had lots of freezes and hangs and it seems to be fixed now. I am a KDE user and installed kde-full. It looks like some required libraries might have changed from 19.10 to 20.04 and that installed the missing libraries and packages. It's been working perfectly sine I did this.
