RS480/RS690 OSS Compiz Achieved

[rvdboom]

Thanks! I'm going to try that!

[zombiepig]

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?!

You may try also try mesa git from PPA/~xorg-edgers repository, I have only provided as small as possible changes to stable mesa in my PPA/stikonas so that possibility of breaking smth will be much smaller.

i was forgetting:

did you use the following variable

LIBGL_ALWAYS_INDIRECT=1

and enabled Dri in xorg.conf?! if you didn't maybe, it's quite the chance that dri isn't enabled, but disabled by default. so you wouldn't be able to run compiz.
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

compiz --replace ccp

and then use emerald with

emerald --replace

since kwindecorator doesn't work well (at least for me).

That's what I was missing - when I added it, compiz started perfectly. This is really fantastic

and is stable also in video playback and fast, even when going with 500+ mbs of ram occupied in compiling and the processor at 100% load. i'm really impressed how well compiz works on the radeon driver. the devs have really done a real good job.

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

Hi,

I followed the instructions, i.e.

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

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.

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:

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

I tried without the TexturedVideo option and it does not seem to make any difference.

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:

direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)

but the X log file says DRI is activated:

(II) RADEON(0): Direct rendering experimental on RS400/Xpress 200 enabled
