Re: [Solved] Suspend/Hibernate under Debian

To suspend to Ram under Debian, the best doc is the included one, ie,
The online version is at
Suspend to RAM
Please read it through carefully before continuing.
My machine is not in the whitelist, ie, it is a "unknown machine", so I
have to find workarounds.
What doesn't work:
s2ram -f -a 2
s2ram -f -a 1
tested under both the text console mode and X.
The numeric argument for option -a is from 1 to 3, specifying s3_bios,
s3_mode or both (1=s3_bios, 2=s3_mode, 3=both).
So my workaround would be:
* passing acpi_sleep=s3_bios to the kernel
* Since kernel 2.6.16, the acpi_sleep parameter can be set during runtime
(no reboot needed) in /proc/sys/kernel/acpi_video_flags, with "1" for
s3_bios, "2" for s3_mode and "3" for both.
Better to test under the text console. When it doesn't work for
me, I get a blank screen upon resuming. I can hear the hard disk
spinning, and I can see the the wireless LED come on when
resuming. CapsLock gets proper responds as well. This means
everything works fine except screen display. I just press up key
and correct the prevous command blindly, until that I found
's2ram -f -a 1' works, then tried it under X.
