Thank you for your bug report. Can you corolate the freezes with specific actions or e.g I/O use? Could look if there is anything printed in the journalctl logs at the time of the hang? Could you try if it's happening on a wayland session as well?

Thank you for taking the time. I have a hard time pinpointing the exact moments it happens. It's a short freeze, then it works again. Irrational. Didn't happen in 19.04. One occasion is when working with LibreOffice Version: 6.3.2.2 and Calc. When opening a document from inside Calc it happened when scrolling down a long list to find the right one and the window "rendering" (not an expert) seemed to have a problem keeping up. Mouse freeze for a millisecond. Also when opening Calc and trying to do something inside to fast, like moving the mouse to the menu before it's done opening and rendering the window content, the mouse freeze for a millisecond and work again. If you see what I mean.

Could you add the journalctl log?

Didn't know what to include. It's long even if I do -d. But I found an error with dmar. Not sure what it stands for but it led me to turn of virtualization in BIOS. Crossing my fingers but it seems better. Though some apps start very slow compared to 19.04 like FileZilla and FreeCAD. Could be another thing or. Will see. The problem has been kind of irrational.

Problem is still present. Happened when running ClamAV, that took up a lot of memory so that's one thing to change but I had the same setup in 19.04. Can also appear in FireFox (70.0.1, used a lot) when using Twitter. Perhaps a js running away? Will take a closer look in the console next time. I also had VSCode open (runs js right?). I'm not an expert but something around memory and multitasking is wrong in 19.10 that wasn't there in 19.04.

Instead of posting all of journalctl what should I look for? Thanks.

Seems to be an issue with the graphics drivers.

Is it easy to uninstall 100% and go back to default drivers if wanted? Like to have as clean installation as possible but if this helps I might give it a try.

I don't have any specific hint for what to look at in the journal no, just hints of what the problems could be. You can switch drivers in software-properties-gtk

Please open two Terminal windows.

In one run:

  dmesg -w

In the other run:

  journalctl -f

Now wait and reproduce the freeze a few times. Each time look at those two Terminal windows and tell us if you see any particular messages just after each freeze.

Disabling swap helps.

A new kernel will likely solve the problem.
