Hello, I'm using Linux and when I had tried to execute chimera this message appeared:

"OpenGL misconfiguration detected. /usr/lib/libGL.so.1 differs from /usr/X11R6/lib/libGL.so.1. Please read installation instructions."

I said it several times to my system administrator and he solved it using your instructions (see below):

"If Chimera terminates with the error OpenGL misconfiguration detected, that means that you have two different versions of libGL.so installed -- one in /usr/lib (installed by your graphics card drivers) and one in /usr/X11R6/lib (possibly installed by Mesa, which if so would mean no hardware graphics acceleration if this version were used). Reinstalling your graphics card drivers should remove the /usr/X11R6/lib version. Alternatively, you could rename or remove the /usr/X11R6/lib version yourself. With the latter approach you might want to verify that all OpenGL applications that you use continue to work before permanently removing the library. On startup, you may see the warning Xlib: extension "Xfre86-DRI" missing on display "0.0". That means that there was no graphics driver found for your card that uses the DRI, direct rendering interface, technology for fast 3D graphics. The solution is to either ignore the warning or to upgrade your hardware and software (see Mesa/OpenGL issues below)."

The problem is that when I reboot my computer the problem still appears and we should do the same procedure explained above. We can't configure the system conservating the libraries of my card drivers (/usr/lib) without removing the Mesa ones (/usr/X11R6/lib). How can we solve the problem?

We will be waiting for your response.
