[Bug 1888571] Re: [Ice Lake] Screen flickering and glitching after install
This past week or two I've noticed that this issue is solved! I have apt upgrades automatically scheduled every so often, so I imagine there was a kernel release that fixed this issue.

Re: [Bug 1888571] Re: [Ice Lake] Screen flickering and glitching after install
I’ve also had some issues with the audio, but I’ve been able to fix that up by fiddling with pulseaudio. Re the bug fix, should I try a clean install? This isn’t optimal since I’m mostly set up now, but would this help the bug fix take effect?

I’ve also had this thought. I’ve tried this, but the flickering will start before then, usually during the startup splash and login screen.

[Bug 1888571] Re: [Ice Lake] Screen flickering and glitching after install
"nomodeset" will disable all hardware graphics support so it will use high CPU and likely cause screen tearing. That's not really a solution so you should remove "nomodeset" as soon as you can. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1888571 Title: [Ice Lake] Screen flickering and glitching after install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1888571/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
