FWIW... IIRC EDID (and DCC?) are the way the computer asks the monitor "hey, what resolutions do you support?" -- they are the reason we don't need to manually specify modelines in xfree86.conf anymore. If it can't talk EDID to DVI-I-2, I would expect a monitor plugged into it to either get a generic "hopefully works anywhere" VESA mode line 800x600. I once had an LG 2010 LCD monitor where over DVI-D, EDID worked fine, but over D-sub, it negotiated an incorrect modeline. I worked around it by manually specifying a "2048x1024twb" type modeline each time I connected the laptop to that monitor. > I didn't find any relevant Debian bug reports.

Assuming there's nothing in Xorg.0.log either, I would next check xrandr's output to see what modelines it knows about. If you have a computer that works correctly with that monitor, or a monitor that works correctly with that computer, you should compare with its xrandr. _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
