I have an old reliable workstation that was 16.04 until a couple weeks ago. I upgraded to 18.04 and then after a few days to 20.04. On both 18 and 20, video in Firefox is horrible, like 1.5 frames per sec, and the mouse is very laggy, move it across the screen and it will disappear and reappear. None of this happened w/ 16.04. Also, none of this occurs in other apps. I thought I had clobbered the machine with the new OS, but I can run openshot and gimp at the same time and have no mouse/video issues. Also, audio seems fine, Pithos plays Pandora with no issues. Its an I3, 4 core, with 8GB RAM.

Any suggestions (beside upgrading the box!) would be appreciated.

How do I update these, if that's what is required?

  • Boot with a live USB, and check if the problem persists there. It may be an issue with the upgrade. – Archisman Panigrahi Sep 10 '21 at 16:29
  • Hello. @alabamatoy. I agree with Archisman. I think you need a fresh install. I3/I630 works fine in 20.04 – jpbrain Sep 10 '21 at 16:31
  • Phooey. Not what I wanted to hear, but I appreciate all the help. Time to wipe and reinstall..... – alabamatoy Sep 13 '21 at 14:24
  • Unfortunately for me, yall were right. A fresh install and my nice video and cooperative rodent have returned. Thanks for the help... – alabamatoy Sep 19 '21 at 21:03
