Apple yesterday released “X11 Update 2006” which addresses several issues in the X11 for Mac OS X package, enabling it to better handle:
• GLX stereo visuals
• offscreen rendering to GLX Pbuffers and Pixmaps
To tell X11 to take advantage of stereo visuals, enter:
$ defaults write com.apple.x11 enable_stereo -bool true
X11 for Mac OS X offers UNIX users the ability to run thousands of X11 applications concurrently with other Mac OS X applications.
• Mac OS X 10.4.8 or later
• X11 1.1 or 1.1.1
