Description sancaktar.1 2011-03-05 18:53:20 UTC 
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
