Repair 'Ugly UI' in Gnome After Removing KDE?

[LiamMaru]

So, I had to install KDE as it was listed as a requirement for a piece of software we've acquired at work, however after questioning the rationality of doing so, it turned out to be a miscommunication from the vendor - so, as a Gnome user, goodbye KDE.

However, after removing KDE, I notice the Gnome UI is significantly less 'pretty' and indeed usable as a result, than I remember it being:

No folder icons, other things.

Is there some way I could 'repair' my system such that it would look like it did, before the KDE debacle? I could reinstall Ubuntu - this is a new machine and that is entirely possible - but I'd like to find another way to potentially save a bit of time, and hopefully learn a few things along the way.

I had to do something like this for myself after i took Macbuntu for a spin (If you are using macs or want to show up some mac users, do it) The best thing i learned to fix this with is to sudo apt-get autoremove gnome; sudo apt-get install gnome in the terminal and low and behold, it was fixed in a matter of seconds (Well minutes but yeah)

Hmm, thanks cheat117, that seems to have done the trick, turns out I'll be reinstalling Ubuntu anyway, but aside from the grub screen and the login screen (which became debian-esque), it seems to have repaired most of my UI.

It also added a few new things (I noticed the debian package manager among other things), so I'd caution anyone else who tries this in future.
