Hi and thanks for the reply,

It doesn't seem to be caused by Ctrl always pressed. Ctrl works normally
and Alt-Del doesn't trigger Ctrl-Alt-Del action. I tried to play with
keymap settings (in Xfce and in /etc/defacult/keyboard) and nothing
helped.

I tried login to an account with empty $HOME and the problem appears
even there, but I noticed that it is not necessary to login to KDE and
then back to Xfce to get the normal keyboard behavior. It is sufficient
to log to Xfce, then logout and login again.

I also tried to replace GDM by KDM and the problem appeared even with
KDM. If I do not use ?DM and start XFCE by startx command with
startxfce4 in ~/.xsession, then the problem doesn't appear.
