Re: [gpm] ACPI S1 - Standby

["kapetr" <kapetr mizera cz>]

Hello Richard,

first just a Note:

If someone ask in Forum a question: "How to do something", then the
Answer, which absolutely do NOT want hear is such containing only:
"Why do you want to do that ?".

But even if it should be clear - I will answer:

Why not!   - just a joke :-)

Why it is useful - it is NOT good idea to switch off computer for
e.g. just 20 - 40 minutes. Electronic and mechanic components are
very stressed by on/off (cold down - warm up, great current peaks,
...).

This is the reason why clever authors of APM, ACPI use not just
S3/4, but even S1 state! 
BTW: on some PCs do not work S3 properly - so S1 is only
alternative.

So it is bat thing, that GNOME (its power manager) do not let this
possibility  (S1) and moreover do not let such elementary thing like
suspending monitors!

---------------- original question:
Hello,

is there any possibility to put Ubuntu 10.10 into ACPI S1 mod ?

With gnome-power-manager or some other utility ?

PM-UTILS also do not support something like pm-standby.

And what about sysfs/procfs ? I just don't know haw to use it.

See also please my thread :
http://ubuntuforums.org/showthread.php?t=1679036 and
http://ubuntuforums.org/showthread.php?t=1681648
(I thing that GNOME prevents to sleep monitors manually with xset
dpms force off)

What would make me happy also is:

gnome-pm lets me select as action for :
Standby (S1)
Suspend to RAM (S3)
Suspend to disc (S4)
menu to decide manually ("interactive" ***)
user command to call

but ... unfortunately it lets me select only STR/STD :-( Why ?!

*** if I select "interactive" in
/apps/gnome-power-manager/buttons/suspend with gconf editor, then
this is set back if I run /system/settings/gnome-pm :-(

I hope someone will help - thank You
