I've already tried Error: couldn't find RGB GLX visual or fbconfig ubuntu 12.04 and a few others, but they haven't helped me.
TL;DR I'm running Ubuntu 16.04 but have installed lubuntu-desktop in order for the display to work with NVidia Drivers installed. OpenGL GLX is not working
Longer version:
I'm on a Dell Inspiron laptop with a NVidia GTX 960M discrete GPU and an Intel HD integrated one, running Ubuntu 16.04.1. After trying a few different drivers that led to a blackscreen or a login loop and still not getting anything when trying cuda samples, I installed the 370.28 driver.
That lead to a black screen again which I solved by adding nomodeset to GRUB_CMDLINE_LINUX_DEFAULT in my /etc/default/grub.
Next I got to a login loop which I couldn't solve by using the default Unity or using GNOME, so I installed lubuntu-desktop which is using LXDE as a display manager. I can successfully login
The problem:
I can't run stuff that's using OpenGL GLX. When running a program that needs the GLX extension, I'm getting freeglut (./application): OpenGL GLX extension not supported by display ':0'
The output of glxinfo is
name of display: :0
Error: couldn't find RGB GLX visual or fbconfig
