I had the same problem, and eventually bypassed it. The Crt_Screen option is supposed to turn off the internal screen, but I found that every time X started up or switched modes, it turned on the internal flat screen.
Finally, I started using dual-head mode, which allowed me to use different refresh rates, resolutions, and even images simultaneously on the internal and external monitors. I also now use Xinerama, which allows me to locate the two monitors side-by-side, and move windows between them by dragging them with the mouse. If you are interested, I could send you my XFree86Config. dbr On Mon, 2002-04-22 at 01:12, Leonard Sitongia wrote: > > Hello, > > I'm running XFree86 4.2 on Linux RH 7.2 on a Dell Inspiron 4100 with a > 1400x1050 LCD display and an external monitor.
