I've installed libdrm, x11proto-dri2 from
And the ati driver from
And mesa from
Now EXA gives fantastic performance, but I still get "Fatal: No GLXFBConfig for default depth, this isn't going to work." when trying to start compiz.
What else am I missing?

i was forgetting:
did you use the following variable
Code:LIBGL_ALWAYS_INDIRECT=1
the above variable forces indirect rendering since for the moment it's the only one providing glx_ex_texture_from_pixmap necessary for copiz to run.
also you need to run compiz with
Code:compiz --replace ccp
Code:emerald --replace

ps. with dri2 and direct rendering this should be even more faster and good.

Slow scrolling
Hi,
I followed the instructions, i.e.
I've installed libdrm, x11proto-dri2 from
And the ati driver from
And mesa from
I managed to start compiz by setting LIBGL_ALWAYS_INDIRECT to 1 and modifying the script to skip check of ati/radeon driver on a laptop.
Almost everything works fine. Performance is very good overall. The issue I have is that scrolling a window and moving a window around is very slow (I don't have the wobbling effect activated).
Any idea? I am running Hardy with an XPRESS 200M (5955) on a HP dv5000 laptop.

vtence - that sounds like the same steps I took. Maybe try making the changes to xorg.conf that are listed here https://wiki.ubuntu.com/RS485 . I noticed a small performance boost after following those steps.

No difference
zombiepig, thx for your help.
Unfortunatly, I still cannot make scrolling perf acceptable. Moving windows is really slow as well.
My xorg.conf looks like this:
Code:Section "Device" Identifier "Configured Video Device" Driver "radeon" Option "AccelMethod" "EXA" Option "EnablePageFlip" "on" Option "DRI" "true" Option "TexturedVideo" "on" Option "GARTSize" "64" EndSection Section "DRI" Mode 0666 EndSection Section "Extensions" Option "Composite" "Enable" EndSection
IIUC it should not be necessary to specify the Composite option, shouldn't it be on by default in Hardy? What's the use of DRI Mode 0666?
I'm not sure what else to try. When I run glxinfo, I get:
Code:direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
Code:(II) RADEON(0): Direct rendering experimental on RS400/Xpress 200 enabled
