Nouveau - Dec 2007 - [Bug 13865] New: DVI corruption with RandR 1.2

http://bugs.freedesktop.org/show_bug.cgi?id=13865

           Summary: DVI corruption with RandR 1.2
           Product: xorg
           Version: 7.3
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: drzeus-bugzilla at drzeus.cx
         QAContact: xorg-team at lists.x.org


When I'm using my Geforce 7300 GT and a DVI monitor, the bottom 10 lines or
so
occasionally fill up with garbage. The data comes from other parts of the
screen, so it's not completely random but rather some kind of transfer
error.

I'm using the RandR 1.2 code as the DVI port refuses to work correctly with
my
monitor with the old stuff.

Update from discussion on IRC:

The problem only appears with a large maximum framebuffer (2720x768) instead of
letting X choose a maximum equal to the panel size (1360x768). Maarten
constructed a patch that solved the issue.

I've tested the code committed and it works nicely. Feel free to close.
