Anyway, after rebooting with the above two changes, Slack no longer causes DisplayLinkManager to chew up my CPU like it did before.
I have not fully tested things but I'm hopeful things work now. |
I found this forum and this suggested solution when I had Slack running
very slowly on Ubuntu 22.04. I can report that I tried the two links above and it worked to fix my Slack issues. Thanks for sharing!
