Bug Description

[Impact]

 * Users of hybrid Nvidia/Intel graphics on KDE Plasma are experiencing performance issues when notebook computers are connected to external displays.

 * In many cases, these users are not warned and/or do not know why their computer is having difficulty rendering. The simple fix is to run in Nvidia (Performance) mode when using external monitors, but users sometimes aren't aware of this when they decide to use the more power-efficient hybrid mode.

 * This has been observed in every model of Kubuntu Focus M1 and M2 computers (all five generations of M-series computers use Intel/Nvidia graphics)

 * The uploaded fix has a simple warning that appears when switching to Hybrid Graphics (on-demand mode): "Not Recommended if Using External Monitors" to act as a deterrent.

 * Granted, this warning may not apply to all users of hybrid graphics, but this is known to be a fairly common issue when using external monitors on hybrid graphics on KDE Plasma.

[Test Plan]

 * Set graphics to hybrid mode (notice no warning)

 * Plug into external montior

 * Notice performance issues

[Where problems could occur]

 * Users can ignore this warning to their own potential detriment.

 * This may not be an issue at all for some users, in which case this warning doesn't apply to them.

I can confirm that this has been tested on several systems at Kubuntu Focus's testing bench and is working very well.
