Ubuntu – Ubuntu 20.04 – Google Chromium is slow after wake from sleep

20.04chromium

As the title says, if I close my laptop lid while Chromium is running and then open it again, Chromium is quite sluggish (slow) when my laptop wakes from sleep. The mouse lags and scrolling is choppy. Other programs seem to not suffer this problem. Restarting Chromium returns it to normal. Machine is Lenovo 81SS, AMD Ryzen5 3500U.

This did not happen with Ubuntu 19.10

Thank You

Same problem for me (ubuntu 20.04 + Chrome 85.0.4183.102). I solved it by simple disabling the Use hardware acceleration when available in Chrome Settings. There you go for a pretty long explanation of the reasons.

Ubuntu – Why does Chrome video performance substantially degrade after waking from suspend in 10.10

Upgrading to the new Chrome 8 beta fixed my problem with HTML5 video completely, since it added GPU acceleration. Flash is still as slugish as ever, but it runs well enough in Firefox, which isn't a problem for me since I've been using Firefox as my "crap, I need Flash for this" browser for a while anyway (I've had Flash disabled in Chrome 99% of the time for a while).

This isn't really an answer so much as an admission of defeat, but pending an actual solution, I think it's probably the most sensible advice for most people.

Ubuntu – Chromium not starting on Ubuntu 20.04

I just got this problem, seemingly out of the blue. Turns out I may be related to a problem I already reported about fonts not loading in the Chromium Snap.

I found the following workaround :

# first close all instances of chromium
sudo rm /var/cache/fontconfig/*
rm ~/.cache/fontconfig/*
sudo fc-cache -r -v
rm -rf ~/snap/chromium/common/.cache/fontconfig/
chromium-browser

This set of commands is a workaround for a problem I already reported here : [chromium] File chooser is not displaying font
