Hello,

thanks for your reply. This is what I suspected, but I don't use NM
and don't recall that any of my networks try to set my hostname (I
connect only to a dorm network, and eduroam, sometimes some dnsmasq
driven lan).

I have no idea who tries to set my hostname and will investigate it
(it really seems that setting my hostname to empty string is the
cause, but still I don't know why. One idea is that something is
corrupting my memory (I would point at i915 driver, but don't really
have time for debugging).

Regards Ladislav Laska
S pozdravem Ladislav Laska

When it set the hostname I had no other way of getting back control of X / KDE3 than restarting the X server. I've solved it by adding two lines into /etc/NetworkManager/nm-system-settings.conf:
