I'm not aware of any trick to make both nv and nouveau working.
Maybe there should be a way to prevent nv (and vesa, but not
fbdev) from loading when KMS is in use?
Yeah, there was a brief discussion about that recently:
http://people.freedesktop.org/~cbrill/dri-log/index.php?date=2010-03-21channel=nouveaushow_html=truehighlight_names=update=Updatedate=2010-03-21
I haven't heard anything about it since.
I wrote a patch for vesa on bugzilla[1] to do exactly that; a similar
one for nv wouldn't be hard.
[1] https://bugs.freedesktop.org/show_bug.cgi?id=26878
Yay, thanks.
I adapted it to xf86-video-nv and it works!
Now we need to trick Aaron to apply it.
Aaron: please, please, please apply.
:)
Sorry for the slow reply. It sucks that this is necessary, but I guess it
makes sense. Comments below.
Thanks for a reply!

https://bugs.freedesktop.org/show_bug.cgi?id=27706 Summary: Blank screen and Error referencing VRAM ctxdma: -12 on NV44A with ubuntu lucid beta 2 (worked in alpha 3) Product: xorg Version: 7.5 Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: critical Priority: medium Component: Driver/nouveau AssignedTo: nouveau@lists.freedesktop.org ReportedBy: mossroy.moss...@gmail.com QAContact: xorg-t...@lists.x.org Created an attachment (id=35110) -- (https://bugs.freedesktop.org/attachment.cgi?id=35110) Dmesg on ubuntu lucid beta 2 installed (does not work) I can't start the ubuntu lucid beta 2 liveCD on a computer with a Nvidia GeForce 6200 (NV44A rev A1) : the screen stays blank after booting. It works properly with a ubuntu lucid alpha 3 liveCD (which probably uses a previous version of nouveau) and ubuntu karmic liveCD (which uses nv driver) I managed to install the beta 2 on this computer through the alternate CD : the behavior is the same when booting on the hard drive. I installed all the updates (as of 16th april 2040) : same behavior I experience the precise same behavior with Fedora live : Fedora 12 live boots correctly (but relies on nv driver), Fedora 13 beta live gives the same blank screen (and also uses nouveau driver). I think this is a regression in the nouveau graphic driver : the version bundled with lucid alpha 3 works, the one with lucid beta 2 (or fedora 13 beta) does not. Here is an excerpt of the dmesg on beta 2 : nouveau :03:00.0: RAMHT space exhausted. ch=0 nouveau :03:00.0: Error referencing VRAM ctxdma: -12 nouveau :03:00.0: gpuobj -12 This error message does not appear when using lucid alpha 3. I found that adding nouveau.noaccel=1 as a boot parameter is a workaround, both on ubuntu lucid beta 2 and on fedora 13 beta My motherboard is a Asus A7N8X-E deluxe, on which a GeForce 6200 video card (branded MSI) is in the AGP port. You will find attached the dmesg of : - ubuntu lucid beta 2 installed (does not work) - ubuntu lucid alpha 3 liveCD (works) - ubuntu lucid beta 2 installed, with nouveau.noaccel=1 (works) lspci gives : 03:00.0 VGA compatible controller: nVidia Corporation NV44A [Geforce 6200] (rev a1) I first opened this bug on ubuntu launchpad : https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/564617 -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

https://bugs.freedesktop.org/show_bug.cgi?id=27706 --- Comment #4 from Xavier shinin...@gmail.com 2010-04-16 14:42:47 PDT --- Ok first, I noticed these strange differences : dmesg-beta2:[6.686828] Linux agpgart interface v0.103 dmesg-beta2:[6.709693] agpgart: Detected NVIDIA nForce2 chipset dmesg-beta2:[6.725012] agpgart-nvidia :00:00.0: AGP aperture is 64M @ 0xe000 dmesg-beta2:[8.814073] agpgart-nvidia :00:00.0: AGP 3.0 bridge dmesg-beta2:[8.814090] agpgart: modprobe tried to set rate=x12.

Unless someone tells you otherwise :) (In reply to comment #3) Here are the different versions of libraries used by ubuntu (I don't know which ones are relevant in this case) : On beta 2 (with all current updates) : xorg 1:7.5+5ubuntu1 libdrmnouveau1 2.4.18-1ubuntu3 xserver-xorg-video-nouveau 1:0.0.15+git20100219+9b4118d-0ubuntu5 kernel 2.6.32-21-generic (on x86) On alpha 3 liveCD : xorg 1:7.5+1ubuntu8 libdrmnouveau1 2.4.18-1ubuntu2 xserver-xorg-video-nouveau 1:0.0.15+git20100219+9b4118d-0ubuntu2 kernel 2.6.32-14-generic (on x86) I suppose you can exclude xorg and xorg nouveau driver, since you apparently get that problem right when nouveau initializes, before touching X. There remains libdrm nouveau and the kernel. The problem is that these are ubuntu packages, and to people external to ubuntu (like all nouveau developers, and many users, like me), it's not easy to know exactly what code that is using. If you could point out the equivalent upstream code, it would help. For libdrm : http://cgit.freedesktop.org/mesa/drm/ For drm/ttm : http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=shortlog;h=drm-next For nouveau drm : http://cgit.freedesktop.org/nouveau/linux-2.6/ More importantly, how do we know that this latest upstream code would not work for you ? -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

Xavier, I had noticed the extra lines regarding AGP x8 (see https://bugs.launchpad.net/nouveau/+bug/564617/comments/3). What is sure is that I did not touch anything inside the PC, or in the BIOS. Is there an easy way to test with an upstream version of nouveau? I might run a liveCD, or even install another OS if it's really necessary.

https://bugs.freedesktop.org/show_bug.cgi?id=27706 --- Comment #11 from mossroy.moss...@gmail.com 2010-04-16 15:31:56 PDT --- Regarding the version number of libdrmnouveau1, normally ubuntu uses a prefix for the version upstream, and a suffix for the patches it applies on it. So, I suppose it is based on version 2.4.18 ( http://cgit.freedesktop.org/mesa/drm/tag/?id=2.4.18 ) The changelog of ubuntu patches are there : http://changelogs.ubuntu.com/changelogs/pool/main/libd/libdrm/libdrm_2.4.18-1ubuntu3/changelog The difference between version ubuntu2 and ubuntu3 seems to be the correction of this bug : https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/547124 , that did not apparently affect me, and that corresponds to the following commit : http://cgit.freedesktop.org/mesa/drm/commit/?id=df32c307e8f81b46ee8aa4dd7222fc18f175bbb3 Not sure if it's really relevant in our case. Maybe version alpha3 of ubuntu had the option nouveau.noaccel=1 by default, and not in version beta2? Which would explain the difference of behavior even if the versions are very close. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. ___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau
