Dear Arch users,
I have latest Arch installed on my desktop at work. In recent two weeks, the system randomly "suspends" at night (I call it "randomly" because it didn't happen every night. And it seems to happen after a random period idle time) when I am off. I can't wake it up in the next morning thru mouse or keyboard.
I tried to disable suspension and hibernation by editing /usr/share/polkit-1/actions/org.freedesktop.upower.policy to change from <allow_active>yes</allow_active> to <allow_active>no</allow_active>
But it doesn't work.
While I call it "suspend", I am not sure it suspend to RAM or hibernate to disk, because I find the CPU fan and power fan still spin normally. RAM light is also on. So it might be a video driver / setting related issue. For your information, I am using nvidia-302.17-2-x86_64 and have dual monitor set up with nvidia-utils-302.17-1-x86_64
This really bothers me a lot. Any help is appreciated. Thanks!
Another question, probably not related to this. What about SMP? Do you have a multi core CPU? And do you also have instabilities, probably including kernel panics, if you run tasks which use both cores under heavy load like compiling the kernel from ABS or converting videos e.g. ripping a DVD with HandBrake or something like that, particularly when X is running at the same time?
