Hi everybody, I'm using the ubuntu Xorg server, with the composite and transparency correctly working. I'm also using the opensource radeon driver shipped with it. I get good 3D performances (~2000fps in windowed glxgears) but transparency (set by transset) is really slow, while I expected it to be more smoother. Would this be fixed using the proprietary fglrx driver? Cheers, fc

What is the ATI video card you use? I just ordered a Radeon 9250 and
hope that is at least as good as my Radeon 9000. I have no experience
with fglrx.
I have built the X.org from the 25 Jan 05 xorg-x11-6.8.1.903.tar.gz and
copied by hand to /usr/local. The rest of the Xfree86 installation is
still intact except for relinking the new Xorg server to X and the X11R6
locale files which I updated to Xorg. I just added this to xorg.conf:
ModulePath = /usr/local/lib/modules
I was originally interested in the improved open source Radeon code with
DRI and have not tried the composite and transparency in your question.
My results were also very good with the Xorg 6.8.1 Xserver:
Sapphire 64M ATI Radeon 9000 soon to be ASUS 256M Radeon 9250
ASUS A8V Deluxe with Athlon 64 3200 90nm and 1GB Corsair Twinx 3200XL
Creative SBLive! not integrated audio (0.7% CPU vs 45% CPU with mpg321)
Alioth Pure64 with monolithic 2.6.10 kernel without 32bit compatibility
