[Chimera-users] libGL.so

[Isaac Amela Abellan]

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.
