[chimera-dev] Xlib: extension "NV-GLX" missing on display ":0".

[Thomas Evangelidis]

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

  Minor opcode of failed request:  5 (X_GLXMakeCurrent)
  Serial number of failed request:  1376
  Current serial number in output stream:  1376

Or with optirun:

$ optirun --debug ./bin/chimera

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
