Nouveau - Aug 2007 - [Bug 11947] New: TFT monitor detected as 1x1 pixels

http://bugs.freedesktop.org/show_bug.cgi?id=11947

           Summary: TFT monitor detected as 1x1 pixels
           Product: xorg
           Version: unspecified
          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 hook up my Fujitsu-Siemens Myrica VQ40-1 (a LCD TV) via DVI, the nouveau
driver refuses to work, citing "no valid modes". The problem is that
it
believes that the screen is 1x1 pixels. Screen works fine on a radeon card via
DVI.

The problem is also present in the nv driver.

It's unlikely this will work, maybe the randr-1.2 driver (Option
"Randr12" "1"
in your device section) will have better luck detecting this. This will only
help if your card has a dvi with a strange i2c bus.

Please make sure you use an up-to-date driver if you are going to test
randr-1.2, as it changes a lot.

Thanks. The RandR 1.2 code nicely detects and drives my monitor. Keep up the
good work. :)

False positive. RandR12 false also gets the panel running with the new driver.
So it's something that has been fixed between what Fedora 8 packages and
HEAD.

False false positive. ;)

Further testing shows that non-RandR mode needs the BIOS to init the DVI
output. But the RandR code can init the DVI fine on its own.
