keyboard not detected

Within the last few weeks, when my computer powers up, my keyboard and mouse is not detected. A reboot usually fixes it, which is very inconvenient.

I've attached both the working and broken X logs.

Guessing here, it looks like all the /dev/input devices are being rearranged. Is there a way to persist the /dev/input ordering? Is there any other log where I should look? (bearing in mind it must survive a reboot, since I can't type anything when it doesn't work)

Re: keyboard not detected

I doubt that the event numbers have any impact - the devices are found and configured (the same way)
What pops out is the amdgpu.dc=0 kernel parameter; other than that, this sounds - a bit - like https://bbs.archlinux.org/viewtopic.php?id=238114 (where the cause was some tool grabbing the input devices away from Xorg server)

If you can rule this out:
- How do you start your session?
- what session is it in particular?
- Do the devices generate input in evtest etc. see https://bbs.archlinux.org/viewtopic.php … 1#p1792561 and https://bbs.archlinux.org/viewtopic.php … 8#p1792608 (but you've evdev already installed and used)

You could also try substituting evdev for libinput to see whether there's some conflict (eg. if your answer to the above includes "GDM")
