Created attachment 498534 [details, diff] xinerama-use.desc.patch Remove the misleading "…is mandatory if you work in multiple monitors setup", which hasn't been true since a while. Modern X systems do not require Xinerama for mulithead any more. Therefore add a hint that it is a legacy extension. Pull request: https://github.com/gentoo/gentoo/pull/5926
x11@gentoo.org, can you confirm that?
Apps still use the xinerama api to query monitor dimensions, and that functionality is enabled via the xinerama use flag in several apps. It's a way that apps even today query the dimensions of monitors running in a single X screen so they, for example, fullscreen to the size of the current monitor rather than the entire X screen that spans multiple monitors. Even if the xinerama extension isn't enabled in X, other components can implement the xinerama interface so that apps can behave correctly when 1 X screen has multiple monitors (e.g. nvidia's twinview in the proprietary drivers being the obvious and widely used example).

Comment #2 is the correct one, so the description is still not good.

This flag instead toggles support for the API which applications use to query the screen geometry on multi-monitor systems. Update the description to match the current behaviour.
