I just installed Ubuntu 11.10 and I did all the software updates. When I went into Additional Drivers, I saw that my ATI/AMD Proprietary FGLRX Graphics Driver is not activated. It says (post-release updates). I tried activating it, but it does not work? Ubuntu is really slow and nothing seems smooth? Also, my laptop fan is constantly on, which makes my laptop SUPER HOT. Someone please help!

do you have multiple graphics cards in the computer? I have a dv7 using xubuntu and I've got a discrete ATI graphics cards and an intel integrated one.
fglrx-update packages will not work. this is a bug
https://bugs.launchpad.net/ubuntu/+source/jockey/+bug/870560?comments=all
read through that.
For xubuntu, I don't require the graphics of unity so the intel card works fine. Try unity in 2D. If fglrx is not installed, find out the outcome of
sudo su
cat /sys/kernel/debug/vgaswitcheroo/switch
you should see
0:IGD:+:Pwr:0000:00:02.0 --integrated graphics processor
1:DIS: :Pwr:0000:01:00.0 --discrete graphics processor
The fan on problem might be that both gpus are powered up even though only one is used.
For the fan problem, try
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
and then re-run: cat /sys/kernel/debug/vgaswitcheroo/switch
this should give
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :OFF:0000:01:00.0
