Sleep mode in Linux?
 

Vista and OSX both support sleep mode for very fast wake up. Do any Linux distros support this?

Yes, it is known as suspend-to-ram.

Yes it is covered by ACPI options in the kernel, so it depends if you have those built.

Usually you do something like 'echo -n mem > /sys/power/state' for suspend to ram, and
'echo -n disk > /sys/power/state' to hibernate.

To find out if your kernel supports this you can do 'cat /sys/power/state' and look for standby mem disk.

Well i uncommented the ACPI_HIBERNATE=true line in /etc/default/acpi-support and the option to suspend now appears but the system won't actually enter sleep mode. Any ideas how i can troubleshoot this issue?

Using Ubuntu dapper on an Acer Aspire 1313 notebook.

I'm quite new to Linux so be gentle.

Cheers.
