Comment 56 for bug 283128

I have the "??" bug on Karmic and Intrepid (2 different computers, both have russian and USA layout, additional typographic symbols enabled).
'setxkbmap' fixes it for some time, though not for long - it will appear again after some time, without any rebooting or something else. I don't have any functional keys as brightness.
The only option for now is to run setxkbmap manualy when this issue appears.
