("framebuffer" perhaps is bad terminology) o No-one except SGI seems to know how to load images into the video memory using DMA. Thus the shadowfb approach used to construct the IMPACT X11 driver, isn't possible for VPro. If someone could figure the latter problem out... we could have full VPro support, including OpenGL, which would be sweet. But apparently this has been less than trivial to achieve. Certainly well beyond my limited skills. ;-) Regards, --=20 Stuart Longland (aka Redhatter) .'''.
