I have openSUSE 11.4 KDE (upgraded to Tumbleweed but that’s not relevant here). The computer is a Dell Optiplex. My sleep (suspend to ram) and wake (restore from ram) work very well. The box can multiboot to windows 7 as well as to Linux.
In Linux, the restore process is triggered by pressing the power button on the front of the case. No other action will bring it awake.
In windows, the restore process is triggered by the power button but also by moving the mouse or touching the Escape key, spacebar etc.
Here’s the question: how do I get the computer to wake in Linux by activating a key (or mouse, whatever) instead of just the power button (which is under the desk and hard to get to)?
I’m having the same difficulty in 11.4, trying to find a way to enable waking from S3 with mouse and keyboard. I’ve tried the links above (and several other forum threads and tutorials) but to no avail. I’ve set all the usb devices in /proc/acpi/wakeup to enabled, but none of them wake the PC from sleep.
I do not thing bios configuration is causing my situation, as it works fine in windows for this PC. I suspect there’s something the links above took for granted as common knowledge which seems rather esoteric to me…
It goes away when I reboot though and when I tried the wake.sh script linked above my system failed to boot to run level 5 until I deleted it. Even with these in place my system does not wake from sleep with any USB device.
