Hi, I'm stumped on this and hope someone can help-
In Zenwalk 6.4 kernel 2.6.33 xfce desktop from the menu I selected 'log out' to bring up that dialog box as I always have but accidently clicked on 'log out' instead of 'shut down' and now after rebooting I get no login screen after the startup procces-
just a black screen with the little white circle.
I did login maually using ctrl-alt-f1 and gained
root access and tried the 'xfdesktop' command to start the gui and received this message: 'warning-
cannot start this screen' (or something very close to that).
Any ideas?
Thanks very much in advance, Keith

I believe you would need the xserver running before xfdesktop will have any effect. Try the command 'startx' at the command prompt and see what happens. Post any errors.

Thanks for the reply...I did try 'startx' during the process as you suggested and no luck.
I have since done a fresh reinstall as I had a couple other minor glitches I couldn't solve. I had saved the error messages but neglected
to copy them to the other drive before reinstalling (oops).
So in short- problem solved and system is running great.
