Thanks! I'm going to try that!
I've installed libdrm, x11proto-dri2 from
https://edge.launchpad.net/~xorg-edgers/+archive
And the ati driver from
https://launchpad.net/~tormodvolden/+archive
And mesa from
https://edge.launchpad.net/~stikonas/+archive
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?
what's your xorg.conf?! do you use ati framebuffer?! are you using textured video?!Quote:

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
and then use emerald withCode:compiz --replace ccp
since kwindecorator doesn't work well (at least for me).Code:emerald --replace
That's what I was missing - when I added it, compiz started perfectly. This is really fantastic :DQuote:

Hi,
I followed the instructions, i.e.
I have also enabled DRI in xorg.conf and checked the X log file and everything looks fine. EXA is activated, along with DRI and PageFlipping.Quote:

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.
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:
I tried without the TexturedVideo option and it does not seem to make any difference.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:
but the X log file says DRI is activated: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
