Turns out it was MATLAB causing the problem, and you need to disable the MATLAB Server service from running (Why the hell was it running by default anyway). Details here.

It used to work, but recently when I attempted anything that wanted to use OpenGL it would report “can’t create gl rendering context”.

I tried uninstalling my video drivers, and updating them from HP’s website but that didn’t fix the problem. My graphics card is a NVIDIA GeForce4 420 Go 32M, so I went to NVIDIA’s website, but it appears they basically leave it up to the OEM to supply the drivers.

Anyway, long story shorter, this usenet post (which I found by searching Google Groups for “NVIDIA GeForce4 420 Go opengl“) pointed me to Omega Drivers who describe themselves (himself) thusly:

The purpose of the Omega Drivers is to provide gamers with an alternate set of drivers, ones that have more options and features than the original sets. The drivers contain optimizations, extra features (like OC capabilities), more resolutions and internal tweaks that can give them the edge in a gaming environment over the normal drivers, which are often tailored for synthetic benchmarks.

They have custom drivers for ATI Radeon, NVidia GeForce, and 3DFX video cards in most windows flavours, so if you are having trouble with an OEM supplied driver like I did, you may get better results giving them a go.

UPDATE: Unfortunately the Omega NVidia drivers didn’t support screen rotation, which is more important to me than being able to use OpenGL, so I have moved back to the crappy HP-supplied drivers.

UPDATE II: Turns out it was MATLAB’s fault.
