Laptop LCD monitor turn off"

siggiae · 04-21-2005, 05:45 AM

Hello, on my Dell inspire 8600 laptop is a small button that should turn off the monitor when I "close" the book, and in windows it works, but not in slackware. How can I enable this feature?

Do some searching for the "suspend" feature.

Maybe you can get more info from here: http://ta.twi.tudelft.nl/DV/Staff/Le...tude_d500.html
I think you're basically missing ACPI support (if you chose bare.i instead of bareacpi.i as the installed kernel you'll be missing it.)

Hum... I choose bare.i, but I compiled my own 2.6.10 kernel.... and it don't work... what features do I have to choose in menuconfig?

Goto Power Management Options (ACPI, APM) ---> select Power Management Support and there select all (well almost all, suit it to your needs) inside ACPI (Advanced Configuration and Power Interface) Support. I would recommend you to choose those features to be "built-in" ([*]) instead of modules ([M]) so you don't need to modprobe them after. You may also want to check CPU Frequency Scaling which is used by laptops to consume less battery, however I've never tried this because I don't own one.

Ok, thank you, I will try this when I get kernel 2.6.12, but...can I use my old config file(2.6.10 config file) with kernel 2.6.12 when released?

Yes, just copy your .config file to where you've your new kernel source.
