Unlikely to be a monitor problem. I'm running Wheezy on another disk on this machine without any problem. The dmesg does not report anything unusual. Among the lines are: nouveau [DEVICE] chipset G86 (NV86) irq 48 for MSI (MSI-X) nouveau [DRM] failed to create encoder 0/1/0: -19 fbcon: nouveaufb (fb0) is primary device [drm] Intitialized nouveau 1.1.2/ 20120801 for 0000.01.00.0 on minor 0 > > I decided to reconfigure xserver-xorg > No, dpkg-reconfigure xserver-xorg is not supposed to do anything these > days.

I'm running fluxbox with no desktop environment. Fluxbox comes up. So I guess the issue is that the resolution capabilities of nouveau (and modesetting) are not being accessed even though the module is loaded. Thanks.
