Why I'm not surprised ? :-)

Okay!.. A couple of checks here:

1- Does glxinfo command exist on your system ?
> How do you know that? Well just run this:

Code: (Select All)

which glxinfo

If it's installed you'll have the path of its binary.

> + If answer is yes > go to 2.
 + If answer is NO! > then install the mesa-utils package (for debian-based systems):

Code: (Select All)

sudo apt-get install mesa-utils

2- I hope you're not trying this on VPS-9!.. because it doesn't have a display unless you've explicitly created one with xvfb for example. In which point I don't see the point of looking for the GPU!.

> + If answer is yes : you have to give more details on what are you trying to do.
 + If answer is no and you're doing this on a GPU-backed system with its display and all that, then go to 3.

3- If you get to point 3 and still can't figure out your problem then you're on your own!..

Good luck!

• Yes i have VPS-9 ... 
  
• mesa-utils are installed 
  
• path of glxinfo is  " /usr/bin/glxinfo "
  
• with all these two commands "glxinfo | grep "OpenGL version" & [font=Monaco, Consolas, Courier, monospace]glxinfo | grep "OpenGL" ""  Got " Error: unable to open display" [/font]
