Experimental Virtual Graphics Port Support For Linux 74
With his first accepted submission, billakay writes "A recently open-sourced experimental Linux infrastructure created by Bell Labs researchers allows 3D rendering to be performed on a GPU and displayed on other devices, including DisplayLink dongles. The system accomplishes this by essentially creating 'Virtual CRTCs', or virtual display output controllers, and allowing arbitrary devices to appear as extra ports on a graphics card."
The code and instructions are at GitHub. This may also be the beginning of good news for people with MUX-less dual-GPU laptops that are currently unsupported.

Indeed -- not new, at all.
Similar tricks were used a dozen or so years ago by Mesa 3D to get standalone 3dfx Voodoo cards to output accelerated OpenGL in a window on the X desktop. The 3D stuff rendered on a dedicated 3D card, and its output framebuffer was eventually displayed by a second, 2D-oriented card that actually had the monitor connected.
