With the help of thinkwiki, s2mem cost a little time to work fine. If your computer resume immediately after s2mem, you should try:
modprobe -r uhci_hcd
modprobe -r ehci_hcd
This remove the modules which would awake the computer aumatically. Surely, after your computer resume, you must load these modules for your USB devices.
S2mem is easy and S2disk is not.
First, I got a error “write error: no such device” and i didn’t understand it . Which device is needed? Once I reboot the computer and found a message “Unable find swap signature”. Oh , I havn’t allocate swap space.
Such a stupid error. So
mkswap /dev/sda7
swapon -v /dev/sda7
OK, let me try
echo disk > /sys/power/state
Now, my computer can suspend. But when I press the power button to resume, it boot as like it never suspend. Why？”Unable find swap signature” reminds me. I should modify /etc/initramfs-tools/conf.d/resume. It should be like this: RESUME=/dev/sda7. Then
update-initramfs -u
OK, after these, my computer suspend and resume fine.
