Unvanquished Beta - help installing

Do you mean Unity, the Canonical developed shell of Gnome 3?

I really dislike it, but it is very easy to install Gnome Shell (my favorite) or another DE like XFCE, KDE or LXDe, not to mention the alternative of directly switching to Xubuntu, Kubuntu, Lubuntu, ElementaryOS and who knows how many other 'buntu-based distros.

Personally, in addition to Ubuntu 12.04 Gnome Shell as my main OS, I have also installed ElementaryOS and the beautiful Voyager, a French based Xubuntu respin.

Furthermore on a partition of an old dual-core I have Crunchbang, which uses Openbox as VM and is particularly fast and stable.

Nothing wrong with Mint, which I supported with a couple of donations until the leading developer, Clemente Lefebvre, decided to alienate some users with a disgraceful antisemitic rant.
And for the record, I am not even Jewish.

The difference between the two methods is that the first will add a repository to your package manager, so that it is your package manager that handles and installs the driver. The second method is a manual install, which I have never done since I always under all circumstances rely on the package manager since then your package manager is tracking ALL files related to that install and can cleanly uninstall if needed.

The Xorg-edgers PPA only have the 331 driver according to the information here

Yeah sure, I think we got pretty off topic here, haha. It might be a good idea to move some of these posts.

Booman, since you can't move these last posts I would like to add that, if you are looking for stability, the Ubuntu-X team PPA is probably better.

I also advise against the manual installation of the driver: even if things go well, you are going to face problems with a kernel upgrade, which on Ubuntu is automatic (not so on Mint I believe).
