Installed Ubuntu 16.10 on a Late 2016 Razer Blade Stealth. When I hit CAPS LOCK, the light indicator for it comes on, and it works. But when I hit it again to toggle it off, the screen gets covered in rectangular glitches, sometimes static plays on the speakers, and the device becomes unresponsive but does not reboot. A crash of some sorts.
I'm not sure if this is related to X server, lightdm, or even a kernel crash? I'm not really sure what logs to look at to even begin to start debugging.
If I disable lightdm with:
sudo systemctl stop lightdm.service
then hit ctrl+alt+F1 (no fn key) to get a text prompt, CAPS LOCK has no issue.
What could possibly be going wrong, and how do I start triaging this?
Edit 1: dupe of Uncheck caps lock crashes Ubuntu installation, insufficient answer
Edit 2: some other things I've tried:
- ssh into the box to see if I can collect dmesg and xorg logs as per here. ssh session becomes unresponsive after host crashes.
- try different desktop environments
- try different window managers
