I have had problems using the stereo capabilites of chimera using stereo glasses. I have two computers:

* Mac G5 Quadro PPC + Nvidia FX 4000 with the latest drivers + Chimera X11 version 1.2304 * Fedora Enterprise 2 x Intel Xeon + Nvidia FX 3500 with the latest drivers + Chimera Linux 32-bit version 1.2349

The stereo hardware is correctly installed. I have other applications (X11 pymol) that display stereo nicely in both systems.

On the mac, I have been able to display things in stereo but it crashes or displays weird stuff on the screen. On linux, I haven't been able to display things in stereo.

Any suggestions?

Not sure what's different about chimera, the stereo code is generic quad-buffered stereo OpenGL code. We don't have a stereo Mac (yet), so I can't test it directly, but the Linux version works fine, so I would expect the Mac version to be the same. You might try running chimera with the --nomultisample option to see if that helps. There were multisampling bugs on the Mac, but I thought they were fixed. Please file separate bugs with chimera's Report a Bug dialog (in the help menu) and attach the output of the /usr/X11R6/bin/glxinfo command (on both Linux and the Mac) and, for Linux, the contents of /etc/X11/xorg.conf and any __GL* environment variables you have set, and, for the Mac, the output of "defaults read com.apple.x11". And I will try to figure it out. Greg Couch UCSF Computer Graphics Lab P.S. Are you starting up chimera with the --stereo option or are you switching into "sequential stereo" with the Camera tool? It shouldn't matter, but if only one works, it would be a clue.
