Setting up PRIME or fixing the things I broke trying to set up PRIME
I have a thinkpad T430s, which was one of the earlier models to implement NVIDIA Optimus. I was attempting to set up PRIME so I could use the discrete GPU for more graphically intensive applications (FreeCAD, Blender, games, etc.). I installed the appropriate driver for the discrete GPU (nvidia-390xx-dkms, from the AUR, it's a Fermi series card) and nvidia-prime. prime-run was throwing errors after I did that, so I decided to reboot and see if it helped. After I rebooted, I tried again. glxgears fails with the message "Error: couldn't get an RGB, Double-buffered visual", blender segfaults, and minecraft (as an example of a game) gives the error message "GLX extension not found". FreeCAD still works for some reason I don't understand. I read the relevant pages on the wiki and searched both the forum and google, but was unable to find useful information. If anyone can help me either figure out PRIME or else revert my system to a point where the integrated graphics could run software that relies on OpenGL (assuming setting up PRIME on my hardware is prohibitively difficult) without having to just do a hard reset, it would be greatly appreciated.

NVIDIA driver since version 435.17 supports this method. xf86-video-modesetting, xf86-video-amdgpu (450.57), and xf86-video-intel (455.38) are officially supported as iGPU drivers.
