I asked a question about this on the maillist but there no reply. BTW Fn+F10 works for me with kernel 2.4.19 + ACPI 20020918. The LCD does go off. I do not have the VGA connector cable so I cannot see if it switches to VGA output. Cheers, Jurgen On Mon, 2002-09-23 at 16:11, Mario Lang wrote: hello. I recently got a JVC MP-XP7210DE. First of all, congrats, ACPI worked out of the box with 2.4.20pre7. I have correct ac_adaptor info, correct battery info (even for both slots), and the power button works too under acpid. One remaining glitch I have is getting the internal display to switch off. Under XP, this works fine with Fn-F10. If I do this under Linux, I get a message telling me that this button is not implemented (on the console). Well, that indicates that this LCD display off thing must be done by the operating system. Well, I'm blind[1], and I realllllly don't need that display, and switching it off would save alot of power. Any hint on what I could try to achieve this would be very helpful. Does any of the acpi patches already support that? I think it should be a acpi standard, as there is a screen saver for Windows NT which does exactly that via ACPI (turn the display off). [1] Yeah, don't be supprised, that works really nicely. I use speech and braille output (mostly speech while I'm mobile though), and the display is really just a waste of energy most of the time. P.S.: Sorry to bother the -devel list with that, but it is very very difficult to get competent answers for ACPI questions. All HOWTOs seem to still refer to APM, and well, this notebook doesnt seem to have apm. -- CYa, Mario ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Acpi-devel mailing list Acpi-devel-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org https://lists.sourceforge.net/lists/listinfo/acpi-devel ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf
