FYI, To suspend to Ram under Debian, the best doc is the included one, ie, /usr/share/doc/uswsusp/README.s2ram-whitelist.gz The online version is at Suspend to RAM http://en.opensuse.org/S2ram 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 s2ram -f -a 2 What works: 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. [TIP] 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.
