Mh, XRANDR_OUTPUT_0 = "DVI-0 --auto" gives also no signal. As well as xrandr -s "resolution". Doesn't look like related to ltsp. Either some driver or xrandr problem. This is the problem of kicking out xorg.conf etc. Automatic configuration is wonderful if it works and crappy if you have a problem.
