 (Btw., Johnny, your signatures haven't verified in months. Don't know if the list server is the problem or our corp mail server).

Curiously, it works as root. I checked all files owned by mesa* and couldn't find anything wrong with permissions. Ah, I think I found it): library search path is different for root. That is an artifact of our work environment.

$ ldd `which glxinfo` |grep nvidia
$ 

# ldd `which glxinfo` |grep nvidia
	libGL.so.1 => /usr/lib64/nvidia/libGL.so.1 (0x00007f6de0558000)
	libnvidia-tls.so.346.35 => /usr/lib64/nvidia/tls/libnvidia-tls.so.346.35 (0x00007f6de0352000)
	libnvidia-glcore.so.346.35 => /usr/lib64/nvidia/libnvidia-glcore.so.346.35 (0x00007f6ddd67a000)

Yet, it is strange that it all worked under 6.7 and before.
