Nouveau - Mar 2011 - [Bug 35049] New: Cannot use higher resolutions of monitor

https://bugs.freedesktop.org/show_bug.cgi?id=35049

           Summary: Cannot use higher resolutions of monitor
           Product: xorg
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: sancaktar.1 at osu.edu
         QAContact: xorg-team at lists.x.org


I did a fresh Debian install to sid, upgraded to experimental to get xorg
1.9.99.903 (1.10.0 RC 3) then followed the instructions on the nouveau wiki
(http://nouveau.freedesktop.org/wiki/DebianInstall) to build a new kernel and
drivers.  This was successful.  The problem is that I have a monitor which
supports up to 2560x1600 (which the monitor reports by EDID) but the drivers
will only run at 1280x800.  If I use xrandr to resize, I get a desktop that is
compressed to be equivalent to the larger size, but is actually 1280x800.  I
have tried adding a virtual line to my monitor section and setting the
preferredmode.  These did not help.  The Xorg log shows that it detects the
higher resolutions.  I tried booting the kernel with video=DVI-I-1:2560x1600. 
The kernel FB driver does exactly the same thing, making the text very small
but still actually outputting the lower resolution.  I originally thought that
this was a dual-link problem, but I don't think that 1280x800 is even the
maximum for a single DVI cable.  The propriety driver works at the higher
resolutions.

It appears that this bug report has laid dormant for quite a while. Sorry we
haven't gotten to it. Since we fix bugs all the time, chances are pretty
good
that your issue has been fixed with the latest software. Please give it a shot.
(Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git
versions.) If upgrading to the latest isn't an option for you, your
distro's
bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs
that haven't seen updates since 2011. If the original issue remains, please
make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/
for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
