Desktop effects couldn't be enabled!!

[007]

Sorry if this question has been asked here multiple times but I couldn't find the solution to my problem though I have been through some threads on the topic here. IIRC, when I first installed Linux Mint 7, I could enable desktop effects but later I fiddled with some graphics drivers... NVIDIA just to see and learn.. after that computer showed this and that (problems) but finally it came back to normal. After a day or two, I now tried to enable desktop effects... it gives 'desktop effects couldn't be enabled'

I read through some threads here and here's the results of compiz-check:

linux@linux ~ $ inxi -G
Graphics: Card ATI Radeon RV250 [Mobility FireGL 9000] X.Org 1.6.0 Res 1400x1050@50.0hz

Gathering information about your system...

Distribution: Linux Mint 7

Desktop environment: GNOME
Graphics chip: ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000] (rev 02)
Driver in use: radeon
Rendering method: None

Checking if it's possible to run Compiz on your system... [SKIP]

Checking for hardware/setup problems... [SKIP]

At least one check had to be skipped:
Error: No rendering method in use (AIGLX, Xgl or Nvidia)

I checked hardware drivers but there's nothing... 'No proprietary drivers are in use on this system'

What could be the problem? Could anyone provide me some links or steps so that I can enable the desktop effects? thanx in advance!

I don't get it. You use an NVIDIA and yet you search for ATI drivers !? Mmm
If you are using an ATI then perhaps your problem is related to the ATI catalistic program. I saw something about this subject in another thread, I can point 
it out for you if you need.

You have an ATI graphics card, not NVIDIA, therefore you need to install the ATI Proprietary Drivers before anything.

Open up Hardware Drivers in the menu, install the drivers and activate your card from there.

My bad .. I didn't have NVIDIA ... just got curious, hence I installed it... and fiddled with it a bit and the problem started. If you have any link, please do post here.

@Proxima_centarui
At the same time, I am starting to see I have ATI card but the problem now is that in the hardware drivers, there's nothing. it scans for drivers but comes up with empty box 'No proprietary drivers are in use on this system'

I shall google for ATI drivers but in the meantime please do post if you have any further to say on my problem.

Ok, if you are using an ATI, you will most likely need "catalist" program made for ATI. I am not sure if this will help, but since they refer to the subject in cause, it might just help you:

Hoping it aids.

PS: NEVER mess up with drivers. They can kill you... and your computer.

Well... I did some stupid mistake my installing ATI through Envy yesterday.... it screwed up even booting... had to re-format. Now, nice and kicking...

Problem solved then
