Question Disable backlight of mini LCD when using external monitor? - 02-26-2010, 05:01 AM

Here's the deal: I purchased a refurb Dell Mini 10v from Dell Outlet and received it last week.

I followed the guides on this forum and have successfully installed Snow Leopard 10.6 (and used Software Update to update to 10.6.2).

I also ordered one of the internal bluetooth modules off ebay (shipped from Texas $21) and successfully installed it. I use it with my logitech v470 mouse, GPS receiver (with google earth), and DUN with my Palm Centro.

I have had a few issues with sleep mode (it didn't want to wake up) and solved it by disabling USB Legacy support. I also have minor issues with having to frequently re-pair my logitech mouse (actually, I have to restart to get bluetooth to recognize it again) if I don't disconnect the mouse before closing the lid or putting the machine to sleep.


So things are going pretty smoothly all things considered. My issue is this: I want to run an "extended display" on a second monitor so I can use the machine with higher resolutions. I have already made the external VGA monitor the "primary" one by dragging the menu bar in the display preferences pane over to the external display. This works well.

Now what I want to do is have a quick and easy way to turn off the backlight on the mini's LCD. I want to save energy and it doesn't make sense to power both displays when I'm only going to be using the larger one. I know that I can dim the mini's display down to about half brightness, but I want to turn it completely off.

I found a program called InsomniaX which disables sleep pretty easily and allows you to shut the lid and keep the machine running, but I don't want to do this because, as I understand it, it may be harmful over time because of heat build-up. Also I don't want to spend money on an external bluetooth or USB keyboard when i can hopefully still use the Mini's keyboard, just with the mini's backlight disabled.

I poked around to see if anyone else was doing this, but I didn't see anything right off. I know that our machine's can't do "clamshell"/sleep mirroring on an external display. I thought maybe there was a Mac OSX app out there that might act similar to windows and allow me to "disable" individual displays, including the native netbook display.

I would appreciate any feedback. Thanks!

Also, just a quick edit: I just tested InsomniaX and it does work. I can close the mini and still use my bluetooth mouse and external monitor. While this does turn off the mini's screen, it denies me access to the keyboard and potentially causes overheating problems in the long run.

I would also be interested in being able to turn off mini display. I am set up the same as dimjim with my mini screen set to solid grey to avoid any image burn, but I don't know if that is even an issue with led displays. Turning it off would be the preferred option.

Both Windows (all versions) and Ubuntu can do this. Since Ubuntu can do it, the code to do it is available, all we need is to get that code and compile it into a little app to toggle the display on and off.

Anyone willing to tackle this project? I know I would certainly put it to regular use (and after further searching some Imac users have the same problem - not being able to disable their primary displays properly when running external monitors).

nope, that doesn't turn off the backlight, or disable the monitor, it only changes the gamma

Add me to the list. I'd like to turn off the notebook screen while watching movies through the VGA; I could run higher res if os x recognized the internal screen as completely off without closing the lid so the graphics could be redirected to only the external screen. I do this under Win7 and it works fine.

SwitchResX works, but it's $20 though... ;o(

So it is possible. Just have to find the right command and automate it.
