I just installed blender on my dual screen system running Linux FC2. How do I get blender to use both screens. It seems that the interface is expanded to both screens but all I see is one.
why did you post it twice?: https://blenderartists.org/forum/viewtopic.php?t=33324
what is your dual display setup?
is X running twice?
does X see a massive framebuffer, spanning both displays?
if the window is stretched across both screens, but only one actually shows something, it is probably an issue with your config in that opengl acceleration is only supported on one display the way you have things setup
iirc opengl will work on both displays if you use a single large framebuffer, but it can depend on your graphics card and drivers.
