Hi people So as I said in the subject, after resuming from suspend for about 30 times or so since my last reboot, my keyboard did not seem to work. It is a USB keyboard and I tried unplugging it and reconnecting it. I have a second keyboard permanently connected which is a PS/2. That one also didn't seem to work even after unplugging and reconnecting. All the rest of the system seemed to work fine. My USB mouse works, my WIFI USB dongle works. I can browse the internet etc, just not type. Pressing CTRL+ALT+F2 didn't seem to register either. So I clicked through the GUI and rebooted and lo everything is working again. I found several instances of Arch Linux people having non-responsive keyboards after resuming but none seem to apply here as their threads are several years old and their solution was to install a newer kernel. I'm running 4.19.4, last updated 4 December. Any hints on how to debug this?
