Unable to enter runcommand menu in Ubuntu 22.04 LTS (since uinput changes in commit d417e069)

[carlosefr]

Since the uinput changes to joy2key in commit d417e069, it is no longer possible to enter the runcommand menu in Ubuntu 22.04 (x86_64+X11). I confirmed this by checking out the commit immediately prior to that and reinstalling joy2key, which works.

~~Also, in Ubuntu 22.04 uinput is builtin and not a module, thus the group change that should be triggered by /etc/udev/rules.d/80-rpi-uinput.rules does not work. I ran chmod 0660 /dev/uinput and chgrp input /dev/uinput manually, but this had no effect. I also tried using my user's own group, which also didn't work.~~

I also confirmed that python-uinput is able to generate keyboard events successfully, with the following script:

import uinput
import time

d = uinput.Device([uinput.KEY_LEFT, uinput.KEY_RIGHT])
time.sleep(2)
d.emit_click(uinput.KEY_LEFT)
time.sleep(2)
d.emit_click(uinput.KEY_RIGHT)

I'm not sure what the problem is. If you have any suggestions, I can help debug this.

Edit: After a couple of reboots, /etc/udev/rules.d/80-rpi-uinput.rules is being honored and /dev/input gets the proper permissions. Perhaps I hadn't rebooted after that rule was installed, so this bit at least is not an issue.
