keyboard linux with no-root user, but in "input" group

Its supposed that keyboard linux only work with root user, and this situation cant never be a solution.

I want to modify system to give access to a generic user (example pi user), to execute python from this user instead root, changing permissions…

pi@rpi4:/ $ groups
pi adm dialout cdrom sudo audio video plugdev games users input netdev lpadmin gpio i2c spi
pi@rpi4:/ $ ls -la  /dev/input/event1
crw-rw---- 1 root input 13, 65 nov 24 20:44 

As you can see, ‘pi’ user is supposed to have read and write access to /dev/input/event1, because it belongs to ‘input’ group, and /dev/input/event* files are assigned to group ‘input’, with rw access for users belonging to that group.

I have changed your code to bypass ensure_root() , but even with this, I get this error:

 python3 -m keyboard
/home/pi/.local/lib/python3.7/site-packages/keyboard/_nixkeyboard.py:110: UserWarning: Failed to create a device file using `uinput` module. Sending of events may be limited or unavailable depending on plugged-in devices.
  device = aggregate_devices('kbd')
Couldn't get a file descriptor referring to the console

Any clue?

I actually figured this out. comment out the two calls to ensure_sudo() and place this content into

/etc/udev/rules.d/12-input.rules

content:

SUBSYSTEM=="input", MODE="0666" GROUP="plugdev"
SUBSYSTEM=="misc", MODE="0666" GROUP="plugdev"
SUBSYSTEM=="tty", MODE="0666" GROUP="plugdev"

I am not sure of the security implications of allowing 0666 w+r for everyone on those devices. I would think that doing that will allow anyone (in a multiuser env) to “listen” to keystrokes from other users… so be careful with this.

I can run “pressed_keys.py” just fine on Linux Mint 20.2, adding tty and input groups. Just a typo, at _nixkeyboard.py line 76 warning; change “useradd” to “usermod”. Can the same be done on boppreh/mouse library?
