Default configure a right xorg.conf

Hi guys.
I'm using the last drivers nvidia with a 6600GT , and last xorg and compiz
I was trying to optimize my xorg.conf.
then I saw that there is some option I added to my xorg.conf a long time ago that are not even anymore mentionned in the readme of the last drivers
so I've got few question :

Is the "backingstore" option is still usefull ? It's not mentionned in the readme anymore.


another thing :
I dont know if I need that :
section "Extensions"
Option "Composite" "Enable"
endSection

or add this
section "Extensions"
Option "Composite" "Enable"
Option "RENDER" "Enable"
Option "DAMAGE" "Enable"
endSection

does RENDER and DAMAGE need to be writed in the extention section?

finaly, is there some other option or extentions that are not mentionned in the readme and which can be usefull ?

thanks

for the moment , here is my xorg.conf

Section "Device"
Identifier "NVIDIA 6600gt"
Driver "nvidia"
Option "NoLogo" "True"
Option "TripleBuffer" "true"
# Option "AllowGLXWithComposite" "True"
# Option "DigitalVibrance" "integer"
# Option "backingstore" "true"
# Option "XAANoOffscreenPixmaps" "true"
# Option "CursorShadow" "true"
EndSection

section "Extensions"
Option "Composite" "Enable"
# Option "RENDER" "Enable"
# Option "DAMAGE" "Enable"
endSection

Using the command xdpyinfo you can see which extensions are loaded. You don't need special options for DAMAGE/RENDER. I think that backingstore option was dropped a couple of release ago and I believe it was a Quadro option anyway.

Stuff like RENDER or DAMAGE are loaded by default, so no need to add them into config file.

Backingstore:

This option is used to enable the server's support for backing store, a mechanism by which pixel data for occluded window regions is remembered by the server thereby alleviating the need to send expose events to X clients when the data needs to be redisplayed.

thx guys
so xdpyinfo is very usefull.
Indeed RENDER and DAMAGE extention are already loaded.

and there is a line about backingstore.
if you dont active the option there is
options: backing-store NO, save-unders NO

and if you active it , there is
options: backing-store YES, save-unders YES

So a set it on

here is my xorg.conf now :
Section "Device"
Identifier "NVIDIA 6600gt"
Driver "nvidia"
Option "NoLogo" "True"
# Option "CursorShadow" "true"
Option "backingstore" "true"
Option "TripleBuffer" "true"
EndSection

section "Extensions"
Option "Composite" "Enable"
endSection

that's really better
