Details:
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:
> backend fltk
> plot(1:10)
Xlib: extension "GLX" missing on display ":0.0".
Insufficient GL support
Xlib: extension "GLX" missing on display ":0.0".
Insufficient GL support
panic: Segmentation fault -- stopping myself...
Neoprávněný přístup do paměti (SIGSEGV)
Trying to get info about OpenGL:
$ glxgears
Xlib: extension "GLX" missing on display ":0.0".
glxgears: Error: couldn't get an RGB, Double-buffered visual.
$ glxinfo
name of display: :0.0
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Error: couldn't find RGB GLX visual
...
What to do with Octave+fltk in this case? Does fltk work only on OpenGL
hardware?
