Hi Fred!

Sergii has written a great patch that will tremendously improve support for

there before without XRandR. So if you have a multi monitor setup and your 
system won’t support XRandR we would like to hear from you and try to find a 
solution that is acceptable for all sides. I hope that there is nobody in this 
specific situation but it seems easier to ask in advance than to fix it later.

Sounds great.

First question - this refers only to X11, right? Multi-Monitor support (or lack of) under windows are unaffected?

Second question - what was there "before" which would stop working, so which multi-monitor support is "left out" ? A setup to test it.

Currently I use GNUstep and multi-monitor only in a setup with a Laptop + external screen, which means usually a relatively recent OS. Randr 1.2 has been around almost 10 years. If we don't require more modern features, I probably won't hit these limits. A laptop without xrandr is hard to sue, since only with it the external monitor can be dynamically added/removed.

My more "esoteric" machines are single-monitor setups. Solaris 7 with two Monitors would be a setup? I don't have setups like that.
