Ubuntu how to get "instant on" from suspend

Postby bigs » Thu Aug 25, 2011 22:03

For those that use ubuntu lucid or higher, I found that resuming from suspend, although really quick, was not quite instant on and use as one has to wait for the input password dialogue to appear and type that in, and then there is a 1 second pause, then you are ready to go.

The solution is to remove this resume password login screen, by installing "ubuntu tweak" and then in power management settings, untick "lock screen on suspend". Now everytime you resume from suspend, you can use your UX where you last left off in literally 2 seconds! This is fast enough to put your UX into the PDA/tablet category where instant on is a major feature in these devices.

Another option to change to make the suspend turn off equally seemless is to go into "power management preferences" and in "general" tab select "when power button is pressed" to "suspend".

Now you can literally use your UX like a PDA, powering it on, and off very close to instant, which saves batteries in the long run, since you are more likely to power off your UX more frequently, if you know you can get on again near instantly.
