The code uses OpenGL so your X server will need that option. The exact details will vary between Linux distributions. By way of encouragement, I was recently able to do it using Kubuntu 10.04 on a laptop with Intel and Nvidia cards.

This is not an Octave issue per se so I am closing this report.

There are notebooks with dual graphics card, typically Intel (low energy consumption) and Nvidia or ATI (high performance). I have compiled Octave on a notebook with switchable Nvidia card. Octave runs well with Nvidia on, but if I restart notebook with Intel on and Nvidia off, then Octave crashes after trying to plot with fltk:

Trying to get info about OpenGL:

What to do with Octave+fltk in this case? Does fltk work only on OpenGL hardware?
