I suspect the nouveau driver is swapping or mislabeling the two video streams that the NVS-290 card generates. Here are my clues: Setup - Fedora-13 and nouveau driver (latest yum updates as of midnight) - NVIDIA NVS-290 video card - nouveau exposes 2 outputs to XRandR (DVI-I-1 and DVI-I-2) - The NVS-290 video card has a DMS-59 connector, with a short DMS-59 to Dual VGA cable with VGA connectors labeled 1 and 2. - VGA connectors #1 and #2 are connected to monitors #1(Left) and #2(Right). Behavior 1) At boot time, before the nouveau driver is involved, the boot text is output on the VGA connector labeled "1", which is connected to monitor #1 (on my left). 2) At GDM login time, monitor #1 is clearly assigned to the right of the Virtual screen (its right edge is "impenetrable") while monitor #2 is on the left side. Weird, but in theory just an odd default. But wait. 3) Inspecting the "xrandr" output, it is clear that pixels on the virtual screen that are directed to "DVI-I-1" are going to monitor #2 and vice versa (DVI-I-2 goes to monitor #1). I checked the default situation, then flipped the two halves of the virtual screen back and forth with xrandr, checking the xrandr status each time. 4) The last bit of weirdness is that the xrandr geometry setting commands seemed reversed from what would be expected. Maybe that is the inevitable result of mislabeling the data stream, or perhaps it is an important clue in its own right. My head hurts at the point. Misc 5) Oh yes, I buzzed out the cable, just in case it was mis-wired or mis-labled. It's fine, that is DMS59:VGA2_RED -> VGA#2:RED, etc. Please advise if this should be posted somewhere else.
