I have been doing a lot of work with LibDRM, including Multi-Monitor work on Intel and VMWare. Do you guy’s know if there is an easy way to tell VMWare to add more virtual display’s for testing? LibDRM reports something like 8 different connectors, and several CRTCs, so I know it at least supports Multi-Monitor, I’m just not sure how to tell the hypervisor to enable more than one for testing.
I’m sure this is a question for a better list, but I figured I cannot be the only one interested in working with LibDRM on VMWare.
Thanks in advance, - Rian

Sorry for the late reply. There's an ioctl you may use to set the GUI layout: DRM_IOCTL_VMW_UPDATE_LAYOUT (which would in real hardware correspond to plugging in a set of monitors and arranging them). That ioctl is currently reserved for the master and the Xorg driver is using it if you need a code example. I haven't tested for a while, but it should be possible to have up to eight different virtual "displays" in a single VMware GUI window.
One caveat is that you might need to manually set the number of displays and their max sizes from the VMware GUI to make sure you get enough VRAM to back the displays.

Thanks a ton, I plan to try this out right away.
