Hello,
I am finally writing a post regarding this issue I’ve been having for quite some time now, and that usually ends up being a big hassle and productivity breaker.
Sometimes, in the few days following a system reboot, my laptop’s keyboard can stop working after resuming from suspension (I suspend my computer all the time, and seldom shutdown/reboot). I can’t even log-in to try to sort this out, and I usually just end up rebooting from that screen.
There are some interesting things about this issue though:
- It seems the internal drivers do see the keyboard work, as its backlight turns back on if I click on any key, after it turns off by timeout.
- If the problem does not occur within the first 2 or 3 days after the reboot, it will never happen again (I’ve went with a two month uptime with no issues).
- Some function keys will work, like brightness and sleep, but others won’t, such as the volume controls.
- Pressing keys on the external USB keyboard does not wake up the computer, but doing so on the built-in keyboard does, despite it not working properly afterwards.
I have searched on these forums and Arch’s, but no solution worked for me, ie. reloading the atkbd kernel module (couldn’t even do it since it said it was built-in).
I have also looked at the system journal and couldn’t find anything related to this, but I may have looked in the wrong place.
Does anyone have any idea of what might be wrong here? I’d really like to solve this rather annoying issue 
My laptop is an XMG Fusion 15, and I have the qc71_laptop platform driver installed (through DKMS).
