transparency/HW acceleration - choose one?

[rayyes]

I noticed that running xcompmgr to get transparency disables the hw acceleration.
Let me rephrase that...Adding the following lines to /etc/X11/xorg.conf:


Section "Extensions"
Option "Composite" "Enable"
EndSection

will disable the 3D rendering on my nvidia card.

This is what i get when i run glxgears (with transparecy ON):

$ glxgears
Xlib: extension "GLX" missing on display ":0.0".
glxgears: Error: couldn't get an RGB, Double-buffered visual.

and unreal:

$ ut2004
WARNING: ALC_EXT_capture is subject to change!
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Signal: SIGSEGV [segmentation fault]
Aborting.


Crash information will be saved to your logfile.


I am aware that removing the 3 lines from xorg.conf will bring back the HW acceleration, but do I have to chose one or the other for a particular session? Is it possible to play unreal *AND* have firefox on 50% transparency?

wow no takers on this one?

not even a simple yes or no?

well remember that transparency is still experimental and new so it may not work when i try to run 3d with composite my X crashes. I did see in the readme for my NVIDIA driver that u can add the following line as an option to get composite with 3D:

Option "AllowGLXWithComposite" "true"


i dont know u can try that in ur xorg but it may or may not work.
let me know if it helped or not.
