For some moths now I have run a machine with FC5 and the GNOME desktop, I was happy with it but....

I have updated/added something wihout paying close attention and now have KDE which was unexpected and un-desired

I am able to start a Gnome session but have no desktop icons and open.office seems to have vanished and been replaced with K-Office.

Some have already advised - "get used to it - it's better ! " but in this (learning) stage I think it best to stick with what I know before launching into another unknown area

So what do I need uninstall and/or install to return this desktop to its glorious Gnome-ness

First off, KDE didn't highjack anything, you installed it.

Using the command: yum --help , you can see grouplist, groupinstall, groupremove ...

Use grouplist to find the KDE groupname and use groupremove to remove KDE.

You can also use the switchdesk tool to start a particular desktop by default.

Yum Help shows the grouplists and KDE (K Desktop Environment) is one of the groups

# yum groupremove KDE (K Desktop Environment)

reports that there is no such group

I don't have a switchdesk tool

I knew I should have paid more attention, and I realise that I did have some K applications running in the Gnome environment (Amarok is one example)

The point is now moot

I have unchecked KDE in the 'Add/Remove Software'and uninstalled al these applications.

Now at boot I am presented with a blue screen with NO login options..

How does one do a repair install ?

And, it would seem no mouse or keyboard input -
