evemu-record log (2.77 KB, text/plain)
2017-07-25 14:55 UTC, freedesktop

Description freedesktop 2017-07-20 13:43:30 UTC
libinput seems to wrongly assumes that the input device generating lid events will only generate EV_SW and EV_SYN events (see lid_switch_process). On a Chromebook Oak (and possibly other Chromebooks), the same input device handles both lid events and presses of the power button. Pressing the power button generates events of type EV_KEY, causing the assert in lid_switch_process() to fail, crashing Xorg. This is a regression introduced by commit 4aeb3cc018.

Can you attach an evemu-record for this device please, I'd like to add it to the list of test devices. THanks.

I'm attaching an evemu log showing all actions handled by this device that I'm aware of.

    lid: disable all types but EV_SYN and EV_SW

Note that this is a temporary workaround for the crash, you'll lose the volume keys and the power button because it'll all gets disabled. Please file a separate bug for "Allow key events from lid switches" and assign it to me, I'll try to get to that asap.
