Description
Is there an existing issue for this?
- This is a bug in RetroArch frontend
- I have searched the existing issues
Description
When I start retroarch from the linux vconsole, everything looks fine, but the keyboard doesn't work.
It is not a permission issue.
My user is in the input group.
It doesn't even work when retroarch is started as root.
Switching input_driver to linuxraw fixes it.
Expected behavior
The keyboard works.
Steps to reproduce the bug
- Start retroarch as root or with a user in the input group.
- Try the arrow keys.

Research direction
Reproduce the issue on Alpine Linux 3.21.3 with a Raspberry Pi 3B by starting RetroArch from the Linux vconsole and testing the arrow keys with the udev input driver. Compare this behavior with input_driver set to linuxraw; done means the keyboard works under KMS without changing permissions or running as root.
