Enabling EXA

I've being trying to improve the recent sluggish performance of Compiz, and I'm trying to enable EXA, but without success. On starting X, my Xorg.0.log always contains:

(WW) NVIDIA(0): Option "AccelMethod" is not used

here's my xorg.conf

        # nvidia-xconfig: X configuration file generated by nvidia-xconfig
        # nvidia-xconfig:  version 1.0  (buildmeister@builder57)  Thu Jul 17 18:39:19 PDT 2008

Can anyone help?

AccelMethod is not a valid option. From what I understand by using Google real quick, NVIDIA is either using their own proprietary system instead of XAA or EXA, or always uses EXA, or something. Point is, it doesn't need to / can't be set.

Re: Enabling EXA

it should be a valid option AFAIK.

Doubt it will make much difference, but perhaps try and move these options to the device section instead.

Re: Enabling EXA

Nvidia doesn't use the X builtin acceleration methods .. they have their own proprietary method.

If it's not in the docs, it doesn't exist, when you're dealing with fairly high-use software.

Re: Enabling EXA

OK - cheers!

I's seen a few other people setting it, but I guess they hadn't read the docs either

thanks
