Well it does, but in fact it does not stop to do that, so i get in my console aaaaaaaaaaa.... until i press backspace to stop that.
That may explain why I have seen reports that brightness (I think it was brightness) goes all the way up or down with one keystroke and in some cases the laptop is locked and nothing more than a reboot is left
I tried to find a topic about this were I found some at least partial solution but I don't find it - I write so many posts that it is soon "deep down"
It may also be a kernel issue but I've honestly not (until now) met someone that has made such a deep analysis of the problem
Problems with Fn keys are unfortunately not too uncommon
The only thing I get from dmesg | grep key is " [ 4.809050] Fixing up Logitech keyboard report descriptor "
xev and events produce nothing and showkey results in " Couldnt get a file descriptor referring to the console " so I can't really test this
I am not sure but I think we managed to solve the problem with brightness goes all the way up or down with one keystroke
I think that was on one or more Dell laptops - on the other hand it may have been the almost locked keyboard problem that was solved
