[Enhancement] Add virtual monitor workaround to documentation #1057

Closed Interpause closed 1 year ago

Interpause commented 1 year ago

I recently found a Reddit post (https://www.reddit.com/r/VFIO/comments/wj6zhz/gpu_passthrough_looking_glass_no_external/). Following it, I am able to use Looking Glass without needing a dummy display adapter, which wouldn't have worked for my laptop anyways as I do not have any HDMI or DP ports. I think it would save some trouble to mention the possibility of such virtual monitors in the Requirements page in the documentation. It would also allow users who wouldn't have been able to fulfil the requirement of a dummy display to use Looking Glass.

The IDD the Reddit comment is referring to is a sample driver. We do not recommend it here as it truly is a sample driver and a pretty janky one (basically a poor proof of concept code). If we would include it in the formal documentation as recommendation, we will have to support such a setup which is unacceptable. The good news is that the LG project has recently received funding to develop an IDD that will be integrated into LG. This will be an officially supported solution and will eliminate the need to use dummy plugs and secondary monitor connections.

I see, thank you.

Are there news about a virtual display driver? Is there already a working version that can be tested?

gnif commented 1 year ago

It will be announced when there is a version ready for general usage.
