Save last used state after disconnecting monitor about gswitch

[schlomo]

How about adding a mode that monitors the dependencies and switches back to internal only if there are no dependencies for some time, like 30 seconds? That way you don't have to monitor for specific events but solve the generic case of returning to the internal only mode after a forced switch to dynamic switching.

How about, it sounds like you can detect when the monitor is plugged in, and know which device it is? So:

• if gSwitch was set to 'integrated' when display plugged in, then note this down, note down the display device, and switch to dynamic/gpu
• when the display device is disconnected, check against the previous notes, and notice that at the time the display device was connected, gSwitch was set to 'integrated only', and so switch back to integrated only.
  • of course there is an edge-case here for people who were in integrated only, then attach a display, then start somethign that does need gpu, and then disconnect the monitor
  • such people could simply switch to dynamic mode first though, or not disconnect the monitor. (or you could set the new behavior as an option perhaps)

The initial comment was really just a mental note for myself but I appreciate your responses! I forgot about this issue, but I encountered it the other day and it annoyed me so I'll fix it lol.

@hughperkins Yep that's pretty much exactly how I'll do it. Thanks for doing all the thinking for me ;)
