I'm having trouble getting opengl working with nvidia-drivers. The info in my log file is as follows
Code:
[455206.327] (II) LoadModule: "glx"
[455206.327] (II) Loading /usr/lib32/xorg/modules/extensions/libglx.so
[455206.327] (EE) Failed to load /usr/lib32/xorg/modules/extensions/libglx.so: /usr/lib32/xorg/modules/extensions/libglx.so: cannot open shared object file: No such file or direc$

[455206.327] (II) Loading /usr/lib64/xorg/modules/drivers/nvidia_drv.so
[455206.328] (II) Module nvidia: vendor="NVIDIA Corporation"
[455206.328]    compiled for 4.0.2, module version = 1.0.0
[455206.328]    Module class: X.Org Video Driver
[455206.328] (II) NVIDIA dlloader X Driver  340.76  Thu Jan 22 11:03:05 PST 2015
[455206.328] (II) NVIDIA Unified Driver for all Supported NVIDIA GPUs
[455206.328] (++) using VT number 7


but the file it points to (/usr/lib32/xorg/modules/extensions/libglx.so) is actually a soft link to an ATI driver!
Code:
fred@gentoo ~ $ cd /usr/lib32/xorg/modules/extensions/
fred@gentoo /usr/lib32/xorg/modules/extensions $ ls
libglx.so
fred@gentoo /usr/lib32/xorg/modules/extensions $ ls -l
total 0
lrwxrwxrwx 1 root root 40 Mar 14  2013 libglx.so -> ../../../opengl/ati/extensions/libglx.so
fred@gentoo /usr/lib32/xorg/modules/extensions $


I don't really understand why it points here, where should it point to though? I've selected opengl correctly
Code:
fred@gentoo /var/log $ eselect opengl list
Available OpenGL implementations:
  [1]   nvidia *
  [2]   xorg-x11
fred@gentoo /var/log $

and I have this in my make.conf
Code:
VIDEO_CARDS="nvidia"

so why is it not working? I've seen references to a bug along these lines but not quite found a solution.
My graphics card is as follows
Code:
03:00.0 VGA compatible controller: NVIDIA Corporation G96GL [Quadro FX 580] (rev a1)
and I'm using nvidia-drivers-340.76 with kernel linux-4.1.1-gentoo-r1

Ok, fixed it by just deleting the soft link

/usr/lib32/xorg/modules/extensions/libglx.so

and working now. I used to have an ATI card once but don't know why it has only just become a problem as it was several years ago!
