Got two TFT panels (Daewoo L1711MN) connected on my 7300GT. I always had problems with the EDID of these panels (http://www.nvnews.net/vbulletin/showthread.php?t=70186
) but they worked with the two options ConnectedMonitor "dfp,crt" and ExactModeTimingsDVI with drivers 1.0.8776 with an old Geforce 4 card.
Well, it's a 7300GT now and nothing works at all. When using the two above mentioned options the X server fails to start. It find's "Arnos Instruments L1711MN_ANALG" two times, one connected to DFP-0, one connected to CRT-0. When I remove these two lines the X server starts with 2560x1024 (sounds great) but only one monitor shows up, one stays black. It finds CRT-0 and CRT-1. The modelines should be correct, I created them and they worked with the other card. Even nvidia-settings and KDE show two monitors but one stays black (no, the monitor still works) and says "no signal" - no error concerning unsupported modes or anything.
