enable hibernate or sleep in laptop running Slack9.1

I'm going to need to move my Toshiba laptop, and rather than going through the trouble of shutting it down and rebooting, how can I either sleep, standby, or hibernate with it?

If you have enabled APM or ACPI power management in Linux, you should just be able to shut your laptop lid and it will go into a lower power state. Use ACPI if possible, it is more recent.

I don't own a Toshiba, but some laptops allow you to specify whether shutting the lid is hibernate or just standby. Probably you can set this in the BIOS (you may have to use a configuration utility for your laptop.) I've never tried hibernating in Linux, but standby works fine on my ol' Thinkpad.

There are some cool power management and laptop howtos out there - just google for them.

Hope that helps a little

I have googled and this is the 10th page on the list. GRRRRRR. All the results right now point to results pointing to google. Gross. I wish people would post actual links instead of shouting "Google". That, or don't post at all.

This worked for me on Slackware 10.1 and a Fujitsu Siemens Stylistic 4110 Tablet PC

Basically, if you have acpi compiled in,

echo -n mem > /sys/power/state

will suspend your pc. but the screen will be blank when resuming...
Off to write a little script you go...

Quote:

!/bin/sh

# discover video card's ID
ID=`lspci | grep VGA | awk '{ print $1 }' | sed -e 's@0000:@@' -e 's@:@/@'`

# securely create a temporary file
TMP_FILE=`mktemp /var/tmp/video_state.XXXXXX`
trap 'rm -f $TMP_FILE' 0 1 15

# switch to virtual terminal 1 to avoid graphics
# corruption in X
chvt 1

# write all unwritten data (just in case)
sync

# dump current data from the video card to the
# temporary file
cat /proc/bus/pci/$ID > $TMP_FILE

# suspend
echo -n mem > /sys/power/state

# restore video card data from the temporary file
# on resume
cat $TMP_FILE > /proc/bus/pci/$ID

# switch back to virtual terminal 7 (running X)
chvt 7

# remove temporary file
rm -f $TMP_FILE

As for X
