So yes, something outside of Chimera is messed up. Assuming you're running Chimera on the same computer you've installed the graphics driver on, then you can confirm that driver is installed correctly by examining the output of the glxinfo program and confirming that the OpenGL renderer is a NVIDIA one. If that doesn't work, then it might be as simple as forgetting to reboot the computer after installing the driver. If glxinfo fails, then make sure to read the NVIDIA release notes and try installing the driver again. If you are running Chimera remotely, then it might or might not work depending on which graphics drivers are installed on the remote server and the local client. According to this recent Linux OpenGL meeting (23 Sep 2012), <http://www.phoronix.com/scan.php?page=news_item&px=MTE5MTY>, it sounds like that if both ends have NVIDIA drivers, it might work, otherwise cross your fingers and hope for the best. -- Greg On Sun, 7 Oct 2012, Thomas Evangelidis wrote:

After installing the proprietary NVIDIA drivers I am getting the following error message on start up:
Error initializing OpenGL: X server is missing OpenGL GLX extension Couldn't configure togl widget
Does this say anything different from the one I reported before?

This a graphics driver problem. Chimera fails to start because it can't initialize the OpenGL 3d graphics. Googling nv-glx extension fedora 17 suggests it is a problem with how the nvidia driver is installed. Maybe Chimera is partially getting the software Mesa driver and partially the Nvidia driver. The nv-glx missing warning may not be the actual problem causing Chimera to not start but is probably an indicator of the underlying graphics driver installation problem.

Greetings,
I am running Fedora 17 64-bit with bumblebee and akmod-nvidia on my laptop (the original nvidia drivers could not be installed). My GPU (not sure if this is helpful to know) is GeForce GT 650M and after doing that workaround with the open source drivers, in order to use the GPU I launch each program using "optirun" command (i.e. to launch pymol "optirun pymol", otherwise I get a black screen and the laptop automatically logs out). I have chimera production version 1.6.2 (build 36855) 2012-07-06 17:55:00 UTC, and whenever I run ./bin/chimera, with or without optirun, I see the small start up window "UCSF Chimera, an Extensible Molecular Modeling System" but after a couple of seconds chimera terminates with the following message:
$ ./bin/chimera Xlib: extension "NV-GLX" missing on display ":0". Xlib: extension "NV-GLX" missing on display ":0". X Error of failed request: GLXBadCurrentWindow Major opcode of failed request: 153 (GLX) Minor opcode of failed request: 5 (X_GLXMakeCurrent) Serial number of failed request: 1376 Current serial number in output stream: 1376
Or with optirun:

It is worth mentioning that the small start-up window disappears after saying "initializing OpenGL". Do you have any idea what I can do to fix it?
Thanks in advance, Thomas
