[Bug 1110985] New: TW Plasma Intel driver random freezes
http://bugzilla.opensuse.org/show_bug.cgi?id=1110985 Bug ID: 1110985 Summary: TW Plasma Intel driver random freezes Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Factory Status: NEW Severity: Major Priority: P5 - None Component: X.Org Assignee: xorg-maintainer-bugs@forge.provo.novell.com Reporter: sb56637@gmail.com QA Contact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Blocker: --- Hi, I use Plasma (currently 5.13) on Tumbleweed on a reliable Thinkpad T530 laptop with integrated Intel graphics. (Attaching hwinfo) I am experiencing random freezes of the Plasma desktop. The mouse still moves, but no response from clicking anywhere. I tried killing the Plasma shell related processes in a virtual terminal, but it doesn't help. It's completely random, but happens several times a day and results in lost work. I suspect that this is due to a bug in the Xorg Intel driver. I have not tried the fixes yet, such as switching from SNA to UXA acceleration. First I want to try switching the KWin compositor from openGL to Xrender, which I just now did. If that doesn't help, I'll probably just uninstall the Intel driver and use Xmodesetting. These are probably related bugs, but from Leap: - https://bugzilla.opensuse.org/show_bug.cgi?id=945444 - https://bugzilla.opensuse.org/show_bug.cgi?id=1014999 - https://bugzilla.opensuse.org/show_bug.cgi?id=1047716 -- You are receiving this mail because: You are on the CC list for the bug.

Since my last post here, I've been running the Intel driver still, but with the Plasma compositor using the Xrender backend. It's looking tentatively much more stable. I'll switch it back to the openGL backend soon to see if it starts freezing again.
Ok. Any news you can share with us on this topic? -- You are receiving this mail because: You are on the CC list for the bug.

Sorry, not yet, as I was busy with some important work that I couldn't risk losing to a freeze. I just now switched the compositor to openGL again, and I'll report back here immediately if it freezes on me. -- You are receiving this mail because: You are on the CC list for the bug.

Ok, I just now had a freeze with the openGL 2.0 backend, and I had to kill Xorg to recover. Looks like it's the same as the references I linked in #c4, something about the way Kwin uses openGL exposes an underlying flaw in the Intel driver. -- You are receiving this mail because: You are on the CC list for the bug.
