Discrete-until-done mode

[steveschow]

Another mode I would like to introduce is a discrete-until-done mode, whereby the machine will be temporarily placed into dynamic switching mode. After it has switched to discrete mode once under dynamic mode, it will monitor for when it switches back to integrated, and at that time will automatically switch back to integrated-only again.

The reason for this will be so that a user that needs to run an app that requires discrete graphics can switch to this mode and run that app. When that app exits, then the machine can automatically go back to integrated-only mode.
