Thank you for your reply. I tried a two-headed configuration, with the CRT defined in separate monitor and device sections. That worked once or twice, but usually caused the LCD to bloom. I've tried changing the modules, excluding various ones in some experiments. It seems to be very sensitive to whether the monitor (a Viewsonic G810) is connected, so it's some interaction of the laptop BIOS and DDC, I guess. For example, when I have a single-screen configuration, set to 1280x1024 (so that both the CRT and LCD can display it), and I've turned the LCD off with the keyboard function-key control, then when I fire up X the LCD always turns back on so that both the CRT and LCD are on. I've been looking for a way to keep the LCD off so that I can drive the CRT at a nice high resolution that both the CRT and Radeon support (exceeding the specs on the LCD). -- ==Leonard E.
