Dear Wolfgang, Many thanks for your hints, it seems my problems were due to lack of AltGr which is used (almost universally) to obtain ąęćł etc. I found a workaround which is mapping Win Right as a third level selector in Gnome (Preferences->Keyboard) and it works without any other changes. If I may add my 2c, lack of proper input after otherwise extremely smooth installation spoils the whole experience, it would be enough to give user an option to map AltGr during the install warning him/her of the problems they can get into if they don't. Or maybe this is already solved in lenny installer? After all everybody knows Powerbook keyboard layouts and the are not got going to change :)
Is this option in xorg.conf doing the same thing? > Option "XkbOptions" "lv3:lwin_switch" Piotr -- http://okle.pl
