VM crashes after suspend #56

Open alyssarosenzweig opened 3 weeks ago

alyssarosenzweig commented 3 weeks ago

If I open Steam and idle long enough for Plasma to autosuspend the machine (or at least turn off my monitor), when I unsuspend & turn the screen back on & unlock Plasma, the VM has crashed with

12sommelier: ../sommelier.cc:956: void sl_registry_remover(void, wl_registry, uint32_t): Assertion `0' failed. (EE) failed to write to Xwayland fd: Broken pipe

Hopefully that's fixable..? this is on a Mac Studio, not sure if reproducible on the laptops

update: it's not suspend that's the problem, it's turning the monitor off and on (equivalent to unplugging the HDMI cable and replugging, I think). should repro on a mac mini.

The assert in question is at the end of sommelier's wl_registry_listener.global_remove callback. It is more of a debug feature for ChromeOS and should not be active when used with random wayland compositors. Sommelier's remove callback matches exhaustively against its used interface. That means if a general purpose compositor implements a global interface that sommelier doesn't use it will sooner or later always run into this assert. Does it make sense to submit changes to chromiumos/vm_tools? In any case this needs to at least move to Fedora's bugzilla.
