when using EXA greedy mode, there corruption on mozilla (see attached

I am wondering: IIRC, greedy isn't the default, what's the point of
using it instead of the default?
greedy is useful with driver that doesn't have a full hw exa
implementation : this avoid to use slow fallback.
IRRC greedy is also recommended for the nv driver when using exa on nv50.

So nouveau really works? Great.
yes it starts to work fine for 2D and works is done to improve exa
performance by using 3D engine.
(II) Loading sub module "dri"
(II) LoadModule: "dri"
(II) Reloading /usr/lib/xorg/modules/extensions//libdri.so
(II) NOUVEAU(0): Loaded DRI module

drmOpenDevice: open result is 7, (OK)
drmOpenByBusid: drmOpenMinor returns 7
drmOpenByBusid: drmGetBusid reports pci:0000:01:00.0
(II) NOUVEAU(0): [dri] Found DRI library version 1.3.0 and kernel module version 0.0.10
And you really get DRI?
Yes I even got glxgears on my card :)(see
http://nouveau.freedesktop.org/wiki/PatriceMandin?highlight=%28patrice%29
for a screenshot).
But dri is far from being usable (ie nothing work).
We should really package this driver...
May be you should have to ask some questions on nouveau irc.
It could be experimental on some configurations and not ready for
everybody :
- EXA could be slow (ie greedy mode should be used).
- no real 3D
- may be some cards miss stuff (but in these case, tester could be great).
AFAIK fedora started to package it some time ago, but they stop.
