[EN] Fedora vs. siduction & nouveau capabilities

[GoinEasy9]

I'm trying to get the same functionality from nouveau in siduction as I get in my Fedora 16 install.  Would anyone else care to discuss?

I've been running Blender and Nexuiz on Fedora using nouveau for quite a while.  While I gained these capabilities first in Fedora 15, I still can't get them working on siduction.  The inxi -G is identical on both systems.  The only difference I see if that the version of xserver-xorg-video-nouveau that's running on F16 is in Debian's experimental repo.

But that can't be the only difference.  The version running on F15 goes all the way back to git 20110324.  There is a libgl1-mesa-dri-experimental in Debian (in the Sid repo) that could be installed, but I'm not familiar enough with it to say if it would help.

What I'm really asking if anyone else has tried experimenting with nouveau, or has any idea what may be missing from the Debian version.  I've been Nvidia blob free for quite a while now and would like to figure out how to stay that way in siduction.

Anyway, I'll be experimenting.  If anyone else is interested, please leave a comment, and, I'll post if I find out anything interesting.

maybe someone could even build a custom package you could test...I'm not a seasoned Debian package builder though so maybe someone can chime in to help

Hey DeepDayze
It's not that I need a package.  Nouveau is working fine on all my siduction installs.  It's just not up to par with Fedora when running programs that rely on heavy use of 3D.  I was amazed when Blender started working properly with nouveau on my Fedora installs.  It showed how far nouveau had come in the past year.  I'm really just trying to figure out why similar versions of the drivers and xorg are not doing the same in siduction.  
Actually, the same goes for the kwin effects.  I was surprised when some of the effects didn't work in Debian Sid, but worked in Fedora.  
So, we'll experiment a bit and try to figure out why.

For nouveau you should install libgl1-mesa-dri-experimental and the xserver from experimental could help.

[DeepDayze]

GoingEasy9: Perhaps your findings can be passed along to the debian developers so maybe the problem can be isolated and fixed in Debian. I myself used to run Fedora up till F5...now running debian exclusively

[GoinEasy9]

Thanks towo, those were the files I was looking at, at least I have a second opinion of what I need.

@DeepDayze  I'll definitely post my findings.  There's no reason siduction should be any less functional than Fedora, and, if pulling some files from experimental will make it so, so be it.  Previously, pulling from experimental was an experiment in terror, but, now that I see that the versions in experimental are the same as I'm using in stable Fedora, it doesn't seem to be that big a deal.

[DeepDayze]

its true pulling stuff from Experimental is risky for  people who are not that skilled as the Experimental stuff CAN break things. I've installed KDE 4.7.4 and the latest Digikam from Exp and so far no showstopper issues

[GoinEasy9]

Seems a new xserver-xorg came in with the updates today.  Looks to me like the version in experimental and the one in Sid are both the same.  That and the installing of libgl1-mesa-dri-experimental didn't affect the problem running blender.  Kwin's 3D effects are working nicely though.  The cube on the dual monitors looks amazing.

So maybe a bug in the blender version in debian that could be triggered by xorg and the nouveau driver?

[GoinEasy9]

Just tested Nexuiz and it started, but not in full screen as it does in Fedora.  Which actually is a plus because it leaves the monitor setting borked in Fedora, and I have to go in and redo them in system settings.  I guess it's not really set up with dual monitors in mind.  In siduction, trying to start the single user mode blows up, needing a hard reboot.  

Some of the errors I found in messages:

When I get some time I'll google some of these error messages and see if I come up with anything.

@DeepDayze  Hmmm, checking the versions of Blender and Nexuiz.  Why haven't I done that already?

Edit:  Blender version in Sid is 2.61, version in Fedora 16 is 2.59.  It seems that it's a nouveau problem.
