Nouveau - Jun 2010 - [Bug 28449] New: I messed up and now nouveau doesn't work.

https://bugs.freedesktop.org/show_bug.cgi?id=28449

           Summary: I messed up and now nouveau doesn't work.
           Product: xorg
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: David.Ronis at McGill.CA
         QAContact: xorg-team at lists.x.org

xorg.conf 

I mistakenly upgraded xserver on my dual-screen desktop (I had intended to do
so on a laptop running a totally different driver).  I had been using nouveau
stably for quite some time, and now it's stopped working.  [I also have
upgraded pixman, xf86-input-*, mesa, xcb/libxcb, xf86-video-nouveau, drm, and
various proto's].   

When I run startx, on the console I see:

(EE) NOUVEAU(0): Output position loop. Moving VGA-1 to 0,0
X: pixmap.c:118: AllocatePixmap: Assertion `pScreen->totalPixmapSize >
0'
failed.
xinit: giving up

(I'll upload my xorg.conf file and Xorg.0.log files)

This is my main machine, and need this fixed urgently.

Try this hack:

I added the patch and reinstalled.  I get further, but now I see:

EE) NOUVEAU(0): Output position loop. Moving VGA-1 to 0,0
(EE) AIGLX error: dlopen of /usr/lib/dri/nouveau_dri.so failed
(/usr/lib/dri/nouveau_dri.so: cannot open shared object file: No such file or
directory)
(EE) AIGLX: reverting to software rendering
X: ../../../include/privates.h:122: dixGetPrivateAddr: Assertion
`key->initialized' failed.

It looks like nouveau_dri is in mesa, and is enabled by
--enable-gallium-nouveau.  I've enabled it and am trying again (this
wasn't
necessary in the past).

rebuilding mesa with the extra --enable-gallium-nouveau seems to have fixed
things.

Thanks

This bug is fixed.

As an additional comment it is still not recommended to install the
experimental nouveau Mesa3D libraries systemwide.
