Description of problem:
Program doesn't start, reports an error related to my graphics card.  Fresh install of Fedora 10, default video driver.



Version-Release number of selected component (if applicable):
$ rpm -q avogadro
avogadro-0.8.1-6.fc10.i386

$ uname -a
Linux xx.xx.xx.xx 2.6.27.12-170.2.5.fc10.i686 #1 SMP Wed Jan 21 02:09:37 EST 2009 i686 i686 i386 GNU/Linux



How reproducible:
very


What I expect:
an error message or report.  Incompatible drivers?  Improper 3D support for OpenGL? 

  

Actual results:

-from menu:
Applications > Education > Avogadro  (no response, no error)

-from terminal
$ avogadro

==>  It seems related to OpenGL but I am ignorant about which graphics driver is being used by default.  (please give instructions)  In case it is helpful for the package developer, I will wait before following instructions at fedorafaq.org for installing ATI's flgrx.  For Avogadro to be included as a stable package, I think it should work with the default drivers or at least provide a warning error.

If there is no response by about 1 week, I will install fglrx and come back here with a comment.
