Bug ID: 419242 Summary: Support robust recovery from GPU reset in KWin Product: kwin Version: unspecified Platform: unspecified OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: kwin-bugs-n...@kde.org Reporter: shtetl...@gmail.com Target Milestone: --- GPU is a complex processing unit, and some graphics commands can hang it due to various "hazards" that are normally worked around in the graphics drivers, but due to some regressions or bugs, they can still be exposed. When such hangs happen, the kernel driver can detect it and trigger a GPU reset, to bring it back into usable state. Currently, when it happens KWin doesn't recover from it, causing a desktop hang that requires at best restarting sddm or at worst a full reboot. Either way it equals to losing the desktop session. Is there some way to make KWin and the whole session robust that it would handle GPU resets properly, recovering the session on the fly? -- You are receiving this mail because: You are watching all bug changes.
