I've a Thinkpad running on Slackware.

Anyone managed to use IBM ACPI to turn off thinkpad's monitor on
Slackware via Fn-F3? What are the commands to turn off the thinkpad's
lcd screen? I've looked through /proc/acpi directories and managed to
dish out fan info, temperature info, battery info. I've success on
Fn-F12 to hibernate.

Any pointers appreciated.

If I've posted this in the wrong group, please redirect me. My
apologies.

Regards,
Steven.

If you have DPMS enabled in xorg.conf, 'xset dpms force off' will
turn off the screen (yes, including backlight). Then you should be able
to use your window manager to bind that to some key combination. Not
exactly the answer you were looking for, I know, but it does work.

Hi,

Thanks for the reply.

I've alreaedy set Option "DPMS" in xorg.conf. But "xset dpms force off"
doesn't do anything (to my system). It behaves as though the cmd was
executed but nothing happened.

A few suggestions:
Try running 'xset +dpms' first and make sure it says DPMS is enabled.
Also, try running 'sleep 1; xset dpms force off', because sometimes the
screen doesn't seem to blank properly without the sleep.
There may also have been something in the BIOS...sorry, I can't
remember; it's been about a year since I messed with this.
Oh, and look at /usr/src/linux/Documentation/ibm-acpi if you haven't
already.
