CrossOver Support - Community Forums

I'm trying to figure out how to start Crossover's wine using a different Xserver. The reason for this is to narrow down a possible input bug in the latest server build. Quake2 has smooth mouse motion using CrossoverGames 7.2, but using wine-1.1.16 and xorg-server-1.4.2-apple37, the mouse motion is choppy. I want to use CrossoverGames-7.2's wine with my Xserver. I tried the following:

Programs->Run Command->Open Shell

This opened Terminal.app and had DISPLAY set to CrossoverGames' Xserver. I ran:

cd Games/Quake2
/Applications/CrossOver\ Games.app/Contents/SharedSupport/CrossOverGames/bin/wine quake2.exe

Quake2 ran in CrossoverGames' Xserver. I quit it and did:
DISPLAY=:0 # which corresponds to my server. I then attempted the same command but got the following error:

$ /Applications/CrossOver\ Games.app/Contents/SharedSupport/CrossOverGames/bin/wine quake2.exe
Application tried to create a window, but no driver could be loaded.
Make sure that your X server is running and that $DISPLAY is set correctly.

recursive shutdown

Running 'xterm' reveals that DISPLAY is indeed set correctly.

Additionally, running xterm with DISPLAY=:3, it fails to connect to CrossoverGames' Xserver... so I'm guessing there's something "special" going on there... any help would be appreciated.

I replied to Jeremy through other channels, but wanted to post this here for general consumption:

We ship our own X11 libraries to go with the X server inside of CrossOver Games.app. We have set the dependencies of several of the Wine libraries (glu32.dll.so, opengl32.dll.so, and winex11.drv.so in Contents/SharedSupport/CrossOver/lib/wine) to reference the X11 libraries inside our bundle via @executable_path-relative paths (where Contents/SharedSupport/CrossOver/bin/wineloader is the executable). As a safeguard, we also set DYLD_FALLBACK_LIBRARY_PATH to include the path to CrossOver Games.app/Contents/SharedSupport/X11/lib for any processes which CrossOver spawns.

In order to avoid conflicts with normal X11, our server and libraries don't use the normal location for the Unix-domain socket. Instead of /tmp/.X11-unix, we use /tmp/.CrossOver. Therefore, by design, our libraries are incompatible with the generic X server and the generic libraries are incompatible with our X server.

So, if you want to use CrossOver's Wine with another X server, you have to make sure it finds the normal X11 libraries, too. Because of the use of @executable_path-relative dependencies in our libraries, this takes some brute force. You can set DYLD_LIBRARY_PATH (no "FALLBACK" in there) to force the dynamic loader to look in /usr/X11/lib preferentially. Or, you can move Contents/SharedSupport/CrossOver out of our application bundle, thus breaking the @executable_path-relative lookups, and use DYLD_FALLBACK_LIBRARY_PATH to resolve the failures that now result.
