I’ve been playing around with various version of XFree86 today, and  
I’ve verified that the remote VidMode extension is indeed broken on  
the XFree86 3.3.6 server. It hangs in the following call:  
XF86VidModeGetModeLine()

This works fine in XFree86 4.0, but XFree86 4.0 isn’t binary compatible  
with previous X servers. I’m working on a temporary workaround, but I  
would stay away from XFree86 4.0 for a while.

See ya,

Yes. Clients built with the pre-4.0 version of the VidMode library will  
not work with 4.0 X servers and vice-versa.

Xlib is fine (I hope! 🙂

## I got a chance to run CivCTP and HeroesIII on X4 with a G200 card, and both worked just fine. They just wouldn’t go fullscreen …-------------------------------------------------------------- Christian Zander \*\* N?ckersberg 76 \*\* 45257 Essen \*\* Germany email: mbox at [minion.de](http://minion.de) \*\* www: [www.minion.de](http://www.minion.de) \*\* icq#: 5322926
