When I went to PSU this morning the first thing I did was find an open, unused classroom that had a projector. I set things up, booted my computer, and there was my screen projected on the wall. The projector in the classroom was a less fancy Hitachi, so it can only do 1024x768. The nouveau driver not only had no problem sending the video signal to it, but it synced my laptop display to the same resolution. Yay! So, armed with this encouraging development I went to FAB 86-01, which has a Hitachi CP-SX1350, capable of 1400x1050 native resolution according to Hitachi. It even says SXGA+ in great big letters on the bottom of it. I plugged things in, booted my computer, and again, there was my screen projected on the wall. And again, the nouveau driver automatically synced my laptop to the projector. But it didn't look as I expected. In fact, it looked exactly as it looked a few minutes earlier in the classroom. So I opened a terminal and, sure enough, xrandr decided that the projector could do a max of 1024x768. WTH? Conclusion: Either the connections through the podium are limiting the signal, or there is a button on the Hitachi to cripple it. Neither sounds very likely to me, but there you have it. Unless, perhaps, someone has a better explanation. Another mystery is why my computer at home recognizes the two external LCDs (mine and Keith's), syncs my laptop screen to their resolutions, but refuses to display anything. What is up with that? Oh, and whether connected to one of the LCDs at home or the projector at PSU, xrandr sees the external device as VGA-1. Does the nouveau driver love projectors and hate LCDs? So it looks like my presentation is going to be at 1024x768. It will suck rocks, but it looks like I'm stuck at that. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
