Greetings, I finally decided to make the switch from KDE3 to 4.6 yesterday.

I have a Debian squeeze installation with KDE 4.6 pulled from the unstable repository. It is an x server that I access from my laptop for almost everything I do.

I am having an issue starting programs (kwrite, dolphin, syaptic package manager, etc.) with kdesu while logged into an x session via XDMCP. I would usually use kdesu from the run command, but niether the run command nor the konsole can get anything running with kdesu. Kdesu seems to work until I enter the password, but the application I want started, never materializes.

I can configure the system to allow root logins, which works fine, but I never need to log in as root, and I do not want root logins activated for remote logins.

Also, it should be noted, kdesu works fine when I plug in a keyboard and monitor and login directly to the server as a local machine. So, kdesu is working normally as expected with local login, but not on remote logins under the same user.

I'm probably missing something simple somewhere and hope one of you can point to the solution. Thank you.

$ /usr/lib/kde4/libexec/kdesu -d -c dolphin
kdesu(2427)/kdesu (kdelibs) KDESu::KDESuPrivate::KCookie::getXCookie: No X authentication info set for display "waldostpg40.local:0.0"
kdesu(2427)/kdesu (kdelibs) KDESu::PtyProcess::exec: [ ../../kdesu/process.cpp : 293 ] Running "/bin/su"
kdesu(2427)/kdesu (kdelibs) KDESu::SuProcess::ConverseSU: [ ../../kdesu/su.cpp : 259 ] Read line "Password: "
kdesu(2427)/kdesu (kdelibs) KDESu::KDESuPrivate::KCookie::getXCookie: No X authentication info set for display "waldostpg40.local:0.0"

Removing my .Xauthority file gets kdesu to work once or twice when I first log in, but if I do anything else with KDE, it stops working.

I suspect it has something to do with the new options for authentication in the /etc/kde4/kdm/kderc file, but I'm lost as to how to resolve the problem. I tried different authentication methods as described in Xsecurity, but no use.

Does anyone have any ideas? Developers? Anyone?

Okay forget it then I've gone back to KDE 3, which is complete and works without the least bit of problems. I hope the KDE team finishes 4 and gets it working and stable and FULLY customizable before Debian stops support for Lenny.
