I have a dell Inspiron 600m laptop that I just got.
I just upgraded from the default 2.4.* kernel to the latest 2.6.12.5 kernel.
What I noticed is that when I press the small "switch" by the lid of the lcd, the lcd screen won't shut off. The 2.4.* kernel doesn't have this problem. I
know it has to be a kernel option, but I just can't seem to find it.
Any suggestions?
*EDIT*
This fix can be found here, follow these instruction, only if you have a radeon card:
Thanks for the quick reply, unfortunately, I couldn't find anything related to "panel button support", nothing came close to those words under the ACPI or Power Management section.
While my laptop is not the same brand as yours, the lid switch on mine is actually BIOS controlled. It sends the lid_closed/open signal to the OS, but whether or not the backlight on the LCD turns off is handled by the BIOS.
Incidentally, that's all that happens. The LCD does not turn off, and if you shine a flashlight at the screen you can still see your characters.
Are you just trying to blank the screen or are you trying to suspend to ram? I don't know if the default acpi scripts will do the trick. I have acpi/suspend to ram working fine on my dell 700m but I had to write a custom acpi event script. Also, if you changed the acpi options to modules, are those modules loaded -- i.e. button, lid, etc.?
I think -- but not sure -- that you need to do a little configuring of your acpi scripts to get it working.

I just want the screen to be "blanked or off" when I press the little "switch"...Like when you close the lcd lid of the laptop and it seems that the lcd has turned off...
I haven't figured it out yet...I'm still picking some kernel options and searching on google
To check what event is invoked, press your "little switch" and then check bottom of /var/log/messages. If it sent some event, it should be easy to handle it in /etc/acpi/acpi_handler.sh script.

No event popped up, as if I didn't press it at all
Originally posted by Jackson1995 Are the lid, button, etc modules loaded? Also, did you restart acpid?
I'm not really sure, I thought that the modules would load automatically? I don't know the names of the modules of the lid, button.... I checked rc.modules, and I couldn't find anything about acpi
"lsmod" will list the modules that have been loaded. Since you compiled them as modules, you should see lid, button etc. listed. If not, you need to modprobe them.
