e2display.py not running

[Christian Bortolini]

Hello,

I have this version of EMAN2:

EMAN 2.0.6 (CVS 2012/08/13 15:17:21)
Your EMAN2 is running on:  Ubuntu 12.04.1 LTS 3.2.0-35-generic x86_64
Your Python version is:  2.7.2

e2speedtest.py works, but e2display.py is not running. The output is:

christian@Edoardo:~$ e2display.py
Traceback (most recent call last):

My desktop pc is brand new, but it has no graphic card. I have tried to install further libraries, but it did not solve the problem. I have also tried these instructions (http://blake.bcm.edu/emanwiki/EMAN2/FAQ/Ubuntu_8.10_error_running_e2.py).
Can anyone help me?
Thank you in advance!

Christian

did you follow the webpage to install pyopengl?
in which step you get problems.

EMAN2 uses OpenGL extensively. You really should have an Nvidia or ATI card in your machine if at all possible. Integrated Intel graphics may be ok as well now, but in any of the 3 cases you need to install the correct OpenGL drivers. If you have a generic graphics card not supporting acceleration, you will need to have Mesa installed (software rendering).

Hello,

I had installed pyOpenGL by following the website instructions, but it wasn't working. I have just installed the Mesa package " libgl1-mesa-swx11-dev " and now it is finally working!

Thank you very much for your help and suggestions!
