UPDATE: Use the fix here instead. This actually works.

Fix for keyboard not working after suspend in Linux distros
This is a common problem with Sony VAIO laptops on Linux and this script aims to fix that.
Update(14/11/2023): The script may not work anymore. Also found out that this isn't just a problem with Arch and Arch-based distros but on other Linux distros too such as Debian, Ubuntu and Fedora. For now the only fix is, right after waking up from suspend, press the Caps Lock button (do NOT press any other button) until the LED light turns on, then your keyboard should be working normally after that.
Clone the repo
git clone https://github.com/TheDragonary/Arch-Keyboard-Fix.git && cd Arch-Keyboard-Fix
and run
./arch-keyboard-fix.sh
WARNING: note that the current working directory must be the directory where arch-keyboard-fix.sh and the other files are located.
Or you can execute all commands at once:
git clone https://github.com/TheDragonary/Arch-Keyboard-Fix.git && cd Arch-Keyboard-Fix && ./arch-keyboard-fix.sh && cd && rm -rf ~/Arch-Keyboard-Fix
The fix involves three files:
- arch-keyboard-fix.sh is the installation script. It copies reset-input-devices-after-sleep.service and reset-input-devices.sh where they belong.
- reset-input-devices-after-sleep.service is a systemd service file. It executes reset-input-devices.sh after every suspend/hibernate.
- reset-input-devices.sh resets
- the atkbd Linux kernel which is responsible for the built-in keyboard of laptops.
- all USB human interface devices.
