Curiously my intel 845-G has had gl applications (freecad and wine based windows games) STARTED working correctly with this update. I see in a latter email that you have a) found a path issue for users vs root, and b) you are using nvidia. This reminded me of an issue I was having with some GL code I use (jogamp based) and nvidia drivers a little over a month ago, this might be something else you want to be aware of. Nvidia is in the process of making a Vendor-Neutral GL[0], which I think is probably a good thing, but they have found that "several applications relied on behaviors or attributes of the NVIDIA OpenGL driver that fall outside of the Linux OpenGL ABI"[1]. Once I figured out it was kmod-nvidia related, this[2] post helped me figure out the mapping to the other links. for now I have had to stick our nvidia machines at 352.79 until either we get our app working with the GLVND API, or elrepo packages a non-GLVND config[1].

This is related to OpenGL/mesa and can be demonstrated with glxgears: $ glxgears libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 154 (GLX) Minor opcode of failed request: 3 (X_GLXCreateContext) Value in failed request: 0x0 Serial number of failed request: 33 Current serial number in output stream: 35 $ This appears to be a common problem, but I found no solutions that apply here since I believe everything is installed and set up correctly. It all worked with CentOS 6.x, x<8. https://www.centos.org/forums/viewtopic.php?t=56273 https://ask.fedoraproject.org/en/question/38116/issues-with-libgl-on-fedora-20-unable-to-load-driver-swrast/
