Inputs dead on resume/disconnect from external display

[J0nnyMak0]

I've been encountering this odd issue for a while now. Every once in a while, after resume from suspend (closing and reopening the lid), either my trackpad or keyboard or both are disabled. Going through another suspend-resume cycle usually fixes the issue and I get my inputs back. There is nothing in dmesg or journal. I'm attaching the part of the log corresponding to the problem resume followed by the suspend-resume cycle that fixed the issue. It seems to happen more frequently when I suspend after disconnecting from external monitors, but I think I've also seen it happen without external monitors being in the picture.

It would be helpful to get a log of sudo libinput list-devices when all inputs are dead.

Thanks. Will do next time, maybe by connecting an external keyboard.

I attached external keyboard and mouse after the latest occurrence of the issue. Attached is the list of inputs with the laptop's built-in keyboard dead but touchpad working.

Hm, and does sudo libinput debug-events show the events normally while Sway doesn't?

Yes, that is correct. sudo libinput debug-events registers key presses on the internal keyboard that has no effect in sway.

FWIW, this just happened when I disconnected my external monitors. No suspend/resume cycle involved this time. I'll change the title to reflect the same.
