+ Disable when running with X server that supports reporting
+ changed regions via ioctl, as this method is simpler,
+ more stable, and higher performance.

- is disabled by default because fbcon will aggressively consume
- the first framebuffer it finds, which isn't usually what the

+console Allow fbcon to attach to udlfb provided framebuffers.
+ Can be disabled if fbcon and other clients

+ the USB bus in device memory. If any pixels are unchanged,
+ do not transmit. Spends host memory to save USB transfers.
+ Enabled by default. Only disable on very low memory systems.
