I installed Mint about 2 weeks ago now and before seeing the forums here I went and performed the 7.04 update in Synaptic.
My laptop still works with no problems and even ended up getting my Fn keys to work (sound, brightness, battery etc...) after the updates
When I found this forum, the night after the update, I saw the first postings saying 'Do not install 7.04'
Some people are saying it broke their Mint, but I have not found a posting on how to remove 7.04 from a working system. I might just have missed it.
As you can guess, being in the noob section, yep i'm a noob at Linux but I am liking it more than other new os's
By the way, GREAT job with this distro.
