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.servicethen 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

I also have a New Razer Blade Stealth and I had the same problem but fixed it installing the razer keyboard driver for linux which you can find here on GitHub and disabling the built in keyboard driver.
There's a PPA for Ubuntu (16.04 and newer):
sudo add-apt-repository ppa:openrazer/stable
sudo apt update
sudo apt install openrazer-metaIf you get dependency errors when trying to install these driver packages make sure that you have enabled the universe repository in Software & Updates. There is also a development PPA (ppa:openrazer/daily).
Reboot, or insert the new module from the terminal:
sudo modprobe razerkbdAfter installing the driver you should see it
lsmod | grep "razerkbd"Second disable the built-in keyboard driver that causes the problem. First find the name of the driver.
xinput listDisable it ("AT Raw Set 2 keyboard" in my case)
xinput set-prop "AT Raw Set 2 keyboard" "Device Enabled" 0If this no longer produces an error, make the changes permanent.
cd /etc/X11/
sudo mkdir xorg.conf.d
cd xorg.conf.d/
sudo touch 20-razer.conf
sudo xed 20-razer.conf Copy the following to 20-razer.conf
Section "InputClass" Identifier "Disable built-in keyboard" MatchIsKeyboard "on" MatchProduct "AT Raw Set 2 keyboard" Option "Ignore" "true"
EndSectionReboot and check that the CAPS-lock key no longer produces the crash.
Jorge Garza's answer helps, but after suspend the problem was back. Adding the fix to /etc/pm/sleep.d/20_razer helps.
#!/bin/sh case $1 in suspend|suspend_hybrid|hibernate) # everything is fine ;; resume|thaw) xinput set-prop "AT Raw Set 2 keyboard" "Device Enabled" 0 ;; esac
as explained here on GitHub
This one is to disable the caps lock on your keyboard so that you dont accidentally crash your razerblade stealth laptop:
setxkbmap -layout us -option caps:ctrl_modifier gsettings set
org.gnome.desktop.input-sources xkb-options "['caps:ctrl_modifier']"Fellas, I found the solution for this issue. I tried it around 10 minutes ago and my machine hasn't frozen yet. Create a script with the following content:
remove Lock = Caps_Lock
keysym Caps_Lock = 0x0000I called mine killcapslockAfter that, from your terminal, run:
xmodmap killcapslockAfter that, your caps lock should no longer lock your PC.
