Power is the correct way to awaken the system. If you have a "sleep" |
| 7 |
key, edit /etc/acpi/default.sh to account for the power-button press |
| 8 |
that shuts down the system. Something like: |
| 9 |
|
| 10 |
case "$group" in |
| 11 |
button) |
| 12 |
case "$action" in |
| 13 |
sleep) |
| 14 |
touch /etc/.acpi_ignore_power |
| 15 |
echo mem >/sys/power/state |
| 16 |
;; |
| 17 |
power) |
| 18 |
if test -f /etc/.acpi_ignore_power; then |
| 19 |
rm -f /etc/.acpi_ignore_power |
| 20 |
>/dev/null 2>&1 |
| 21 |
else |
| 22 |
/sbin/shutdown -h now |
| 23 |
fi |
| 24 |
;; |
| 25 |
... |
| 26 |
|

If you don't have a sleep key, put the above commands in a script and |
| 28 |
call that instead. |
| 29 |
|
| 30 |
Also, you could emerge sys-fs/hibernate, and edit |
| 31 |
/etc/hibernate/hibernate.conf to use /sys/power/state. Hibernate can |
| 32 |
also take care of switching to a text console, hacking video modes if |
| 33 |
necessary, locking the console or X desktop, and so on. |
| 34 |
|
| 35 |
I actually use hibernate with two different configurations, |
| 36 |
hibernate.conf and standby.conf, depending upon whether I press the |
| 37 |
sleep or power buttons. |

Some video drivers do not restore correctly. Use hibernate, or text |
| 44 |
console, or google 'vbetool'. |

Which video card and driver? Are you using opensource drivers (which |
| 51 |
usually work fine with power management) or proprietary ones? |
