I have a HP laptop and at the start of every login screen the whole keyboard doesn't want to work until I fiddle with buttons
I try fn+F1-F9 and sometimes right click on the password prompt and keep tapping Esc until it blinks then I'm able to imput a password
It has always done this on all Linux distributions I can't even get a try open as the whole thing is unresponsive usually works after a few minutes of doing the mentioned process above
It would be nice to get my keyboard working without me having to fiddle with it on every boot
