Anyone help with KDE4 - 101??
 

On Friday when KDE4 was released, like millions of others
I eagerly installed it from the Ubuntu repos and all went
well...but now I seem to have 3.5 and 4.0??

UbuntuGeek.com has a tutorial for how to install and upgrade
so KDE4 is your only interface. All seems logical until the
last paragraph...

"To avoid having to start a second X server for a full session
install xserver-xephyr and run Xephyr :1 & export DISPLAY=:1;
xterm and run startkde in the Xerphyr xterm."

...I came to Linux during the reign of Feisty Fawn, so I'm fairly
new to the lingo. I installed xephyr, but could someone decode
that last line and tell me exactly what I need to type, and into
what, to make the remnants of 3.5 go away??

Thanks,

I think perhaps you misunderstood what he was trying to teach you how to do? xephyr is a nested X server, so it's kinda a way to run a graphical environment in a window of another graphical environment. So the "Xephyr :1" command starts a little window on your screen on display 1, the "export DISPLAY=:" tells all applications in that terminal to put all their graphical apps on the X server at display 1, and the startkde starts kde4 running inside the xephyr.

My guess would be that there are two packages, one something like kde-desktop and one like kde4-desktop. Just remove the kde-desktop. I'm not sure, that's just my hunch.
