           Summary: nouveau fails to obtain EDID from NV11 (nforce IGP)
    Classification: Unclassified
           Product: xorg
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: bonbons67 at internet.lu
         QAContact: xorg-team at lists.x.org

On an nforce1 based system nouveau (KMS) driver only used default (small) modes
while attached monitor can do up to 1280x1024. Looking at
/sys/class/drm/.../edid returns empty file.

  Mainboard: MSI K7N420 Pro
  Monitor: Iiyama E431S, 1280x1024, connected with VGA
  Kernel is 3.4.0 (same applies to all older kernels tried).

System info (lspci, ioports, iomem) at attachment #33464 of bug #26670, the
Xorg.0.log and xorg.conf parts apply to past nv approach on that bug.
