Nouveau - Nov 2007 - [Bug 13323] New: 7600Go: RandR12 fails to drive external DVI

http://bugs.freedesktop.org/show_bug.cgi?id=13323

           Summary: 7600Go: RandR12 fails to drive external DVI
           Product: xorg
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: chalserogers at gmail.com
         QAContact: xorg-team at lists.x.org


On my laptop with a 7600GO, internal 1680x1050 LVDS LCD and external 1280x1024
single-DVI LCD connected.

Setting randr12 to true in xorg.conf results in no signal being sent to the
external DVI monitor.  Instead, the laptop's screen goes a speckled purple
which then bleeds into white, and messes up the colours at the console, too.

Restarting X without randr12 "true" works (but doesn't drive the
external
monitor, obviously), and fixes the console colours.

I'll attach the Xorg log for this session.

A couple of weeks ago I sent in a mmio trace of the nvidia driver initialising
X with this setup.  Feel free to ask for it again.

I see one problem immediatly, i never expected a nv4x range card to have an
output that only works on crtc1, i will fix this when i get the chance.

I was wrong about that (misread the log), but still i'll look into what
could
be the issue.

Oh, darn.  It still doesn't work, with the same symptoms.  The above Xorg
log
is of my most recent failed attempt.

RandR12 now works fine, driving both my internal LVDS and external DVI monitor.
 Marking as fixed.
