after recent sys update system didn't see video driver, and by Husse's advise i did sudo dpkg-reconfigure -phigh xserver-xorg
now video is up but in effect i lost russian layout i cant switch in russian on keyboard as usual : Alt+Shift
and no other hot key is working. by clicking on language ikon in tray i get option keyboard layout gray - not available.
i have shorten sven 4000 keyboard, it was detected perfect at installing, and now...i tried to choose different types of keyboards in preferences, it doesn't work. is there any idea what to do?
