My NVIDIA GeForce 6200 has 3 outputs: DVI, VGA, TV-out. In ubuntu 13.04 and 13.10
nouveau driver detects output connection status incorrectly. If I connect DVI cable
only, nouveau thinks than both VGA and TV-out connected. If I connect VGA cable
only, it thinks DVI and TV-out connected.
Wrong connection status leads to wrong resolution selection. Monitor connected to
DVI/VGA reports preferred resolution 1600x1200, but Xorg ignores it because it thinks
monitor is not connected. Instead it uses TV-out settings with 1024x768 resolution.
WORKAROUND: append video=1600x1200 to kernel command line.

This looks similar to bug #636613, but Xorg.log from #636613 connector VGA-1 is connected while both DVI-I-1 and TV-1 shows disconnected. If reporter used single monitor setup TV-1 should be in connected state. Because symptoms do not match exactly and I will not mark bugs as duplicates.
