I have Linux Mint 12 which has gnome-shell 188.8.131.52 but I would like to update it to 3.6.
So my question is how do I upgrade it?
And also, AltF2 doesn't doesn't do anything, how can I get that working?
Do you have apt-get installed?
Or better yet...
I don't run Linux Mint, but anyway, this is how you do it. ;)
