Support for not suspending when certain things running

[mithro]

Hello,

Certain programs which accesses the hardware directly do not suspend well. (These programs include VMware and similar or things which use libusb.) Suspend should not be attempted while these programs are running.

The attached file when put into /etc/acpi/suspend.d will prevent suspend when certain processes are running.

No, those programs should be fixed.

This is not the only case. You also may want to not suspend for other reasons.

For example, you might not want to suspend while scp transfers are occuring. Or you may not want to suspend while the rsync backup is running.

There are plenty of uses for this useful feature that does not conflict or effect people who do not want to use it in anyway.

On another note some programs cannot be "fixed" (because of the way they interact with the hardware). The only way to suspend is to terminate the program. Terminating random applications (which is the only other option) just because the user accidently suspends (or something thinks it should automatically suspend) is not friendly.

Thanks for your report. Your idea might get more attention and have
the possibility of being implemented if you would submit a
specification for this.

You should first check whether it already exists at the Ubuntu specs
page (https://launchpad.net/distros/ubuntu/+specs) in Launchpad. If
that is the case, feel free to contact the drafter of that spec about
your comments/suggestions. Otherwise you can start writing a spec
following the steps described in
        https://wiki.ubuntu.com/FeatureSpecifications.
