| Many laptops released in 2008/9/10 have two GPUs with a multiplexer | |
| to switch between them. This adds support for dynamic switching when | |
| X isn't running and delayed switching until the next logoff. This | |
| feature is called hybrid graphics, ATI PowerXpress, and Nvidia | |
| HybridPower. |
