Unfortunately Kubuntu-Desktop install destroyed a couple of things.
1) The machine will not shut down, it turns off the monitor, but the machine power stays on and whirrs away, and there is no shutdown dialog
Dang--it worked ok with only apt-get install kde.
Is this fixable with some obscure kde setting?
2)Also the xserver is now not accessible from terminal, making root editing more difficult from user.
Fortunately I enabled root gui login before all this kefuffle
I'm afraid like Linus T himself, I personally prefer KDE, but it seems installing kubuntu-desktop can sure foul up settings on Linuxmint Barbara.
Do hope a KDE centric version of linuxmint is in the works, for Gnome though good is a bit sparse on configurations for me.
Unfortunately I could not get linuxmint beta Ada with KDE to even install the bootloader properly, getting an error17.
Good luck with Bea
