Comment 77 for bug 855124

I checked the patch from comment 15 against 3.1.1. While xrandr is faster switching my screen it still takes a long time (3.8 seconds) to read out the current information.
What is worse during switching or asking the information X is blocking! meaning not even the mouse is moving. This also happens when other applications ask for display information (e.g. wine seems to do that a lot).

I reported a separate issue for this bug 47059
