http://bugzilla.opensuse.org/show_bug.cgi?id=1183479 Bug ID: 1183479 Summary: Graphic glitch and freeze at wake from sleep Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem Assignee: screening-team-bugs@suse.de Reporter: flyos@mailoo.org QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Hi, Running Tumbleweed with KDE Plasma on a Yoga Slim 7 (AMD Ryzen), I have an issue with recent updates, since snapshot 20210305 (I suspect the kernel update to 5.11.2?). When waking from sleep, my laptop screen is completely glitchy (mainly back, with random aspects of my desktop placed randomly on the screen, and the cursor is a rectangle of random pixels), and I cannot unlock the computer, nor access TTY (using Ctrl+Alt+F1). After some time, the screen goes black and the cursor appears again (and can be moved), but the laptop is still completely unresponsive, including TTY. I tested each snapshot since then, nothing fixed the issue and I always have to rollback to previous snapshots. Let me know if I can provide any more useful information.
