Hello,

I am receiving the following error when I try and open a structure running chimera with Mesa 7.0 on Debian 5.

X Error of failed request: GLXBadRenderRequest

Major opcode of failed request: 148 (GLX)

Minor opcode of failed request: 1 (X_GLXRender)

Serial number of failed request: 5334

Current serial number in output stream: 5336

I am assuming that this is related to running an older version of the Mesa driver, but I do not have root on the system and the administrators are hesitant of upgrading the Mesa package in /usr/lib to anything beyond the stable release. The servers do not have access to any hardware based video so doing an updated hardware based driver install won't help either. I am limited to what I can do and only have access to my home directory. Would it be possible for me to compile a newer version of the Mesa driver in my home directory and then compile chimera to use that version of the driver instead of the default in /usr/lib?

Thanks!

If the Debian 5 system is a server, I would remote mount my home directory on my workstation with the hardware graphics driver, and run chimera locally. Or you might be able to copy libGL.so from your workstation to a directory in your home directory on the server and set the LD_LIBRARY_PATH environment variable to that directory. If the Debian 5 system is supposed to be a workstation, I would be very tempted to reboot it with a Ubuntu Live CD and when done, reboot it back to Debian 5, or maybe the administrators would be willing to make it a dual-boot system. Your idea, of compiling a software-only version of Mesa, should work if you set the LD_LIBRARY_PATH environment variable appropriately. In the LD_LIBRARY_PATH cases above you would need to start chimera from the command line after setting up the environment or start chimera after editing the CHIMERA/bin/chimera shell script. Hope this helps, Greg
