Dobry day. There are Debian and Ubuntu latest versions. They installed tightvncserver.
The problem is the same on both: when I connect from Windows machine with any VNC client - buttons on the keyboard seemed confused. Ie all the buttons are not the same. Enter something impossible. This only occurs in the QT app, in regular Notepad all the rules. Also mixed up all sorts of Del, Home, End, Shift, etc.
