[ome-devel] Scripts / Environment Variables / OpenGL...

[Jerome Avondo]

Cheers Josh,

FYI as another work around I just set the environment variables in the script...

from os import environ
import numpy

        envarg = environ.copy()
        envarg["DISPLAY"] = ":0.0"
        cmd = 'glxinfo'
        run = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, env=envarg)

Thanks,

J.
