I've got a weird annoyance on one of my #Linux laptops, and maybe someone knows something I don't... (details continue in self replies)
When I shut the lid, the laptop goes to sleep. Sometimes, when I open it, and it wakes up, the keyboard doesn't work at all. I can fix this by closing the lid, letting it sleep again, and then opening it. Usually that works on the first reopen, occasionally it takes 2 or 3, and on very rare occasion, I have to force restart or ssh in and reboot.

@hellomiakoda I have a Thinkpad at work which does this... On windows 11. Rebooting it works. I don't have the exact model in mind but it was bought in like 2019.

It also wasn't doing that initially, for years.

@cmdrDiscoCat Curiously, when it does it again, try shutting the lid for a minute, then open again. I want to know if that fix works in Windows.
@hellomiakoda I'll try !

@hellomiakoda Well, you know what, I just tried.

Out of hibernation, no keyboard. Lid closed to put it in suspend. Waited a bit. Reopened it. Keyboard still not responding.

The only thing that works is to shut it down completely, and start it again.

I wonder if it happens from cold boot too. Maybe fast boot shenanigans ?
