Hi, I'm running debian/testing on my Dell Latitude (C family) with X 4.0.3. The video adapter is supported through the "ATI" driver and it is recognized as a MACH64 device.
While on an X session, and if connected to an external monitor, I can switch the video output to either the flat panel (LCD) OR to the external monitor by pressing Fn-F7 (this is the CRT/LCD switch function) but not to both devices simultaneously.This quite annoying to me when doing presentations. I dual boot this laptop with Window NT. When running NT, Fn-F7 cycles the video output as LCD--CRT--LCD/CRT--LCD--CRT--LCD/CRT..., so I know the laptop can drive both video outputs simultaneously. Also, I just noticed that selecting "Full Screen" mode in VMware while running in CRT mode switches the display to both LCD and CRT simultaneously! So to summarize, I only get the combo LCD/CRT if I run windows NT either natively or through VMware. Outside these two environments it is just one or the other. Do you have any ideas about what to change, I guess in the X config file, to get to the video modes to work simultaneously under standard Linux? Thank you, -- Pedro
