Yes. Don't use nouveau. The error above is generated because your application is trying to use the OpenGL 4 context creation function (glXCreateContextAttribsARB()) but your installed version of libGL does not have that function. Per the VGL User's Guide, you should always download and install the vendor drivers for your 3D graphics card, not use the drivers that ship with Linux. Nouveau and other "open source alternative" drivers typically have more limited 3D acceleration support, or none at all. ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
