Can both xgl and nvidia X server be run at the same time?

[Animeniac]

I've always used envy to download and install the drivers for my Nvidia GeForce4 MX graphics card. Whenever the Nvidia graphics driver is in use, I can't use compiz (desktop effects) at a resolution higher than 1024 x 768 pixels (that resolution is too low for my tastes) - if I do, I won't get any visual desktop effects (not even the effects on the top bar of windows - instead, the top bar is disappeared). Whenever I download and install 'xserver-xgl' from synaptic, I can use compiz at a resolution higher than 1024 x 768, but I have no screensaver when the computer is idle for the time it is set in the screensaver settings (10 minutes, that is) - instead, all I get is a black screen. Also when I have xgl installed, I am unable to access all the options in 'NVIDIA X Server Settings', including resolution, and I get an error message that has "You appear to be not running the NVIDIA X Server"; and I'm not able to change the resolution in System --> Preferences --> Screen Resolution.

I have re-installed Ubuntu and now I don't want to just install 'xserver-xgl' from synaptic. Is it possible to have 'NVIDIA X Server Settings', Screensavers, compiz and a resolution higher than 1024 x 768 work right at the same time (on a computer using the Nvidia GeForce4 MX graphics card)? If so, what is the solution? Thanks.

Helloooo.......

I have tried the 'compiz --replace' command in Terminal, and I see all these errors:
