HD6950 MST Support on Pop OS 20.10 (Ubuntu-based) Linux
I am trying to get multistream transport (MST) working on my linux computer. Unfortunately, my video card is pretty old (HD 6950) but it generally works well and I haven't had any reason to replace it. I found that I need to add
radeon.mst=1
to my kernel parameters. That seems to work (all displays are detected properly and work intermittently) but the computer display configuration is unstable -- X doesn't load automatically (it did once but it seems like that was a fluke), and the displayport screens don't come on at all. Because of the age of my GPU I can only use the 'radeon' driver not the newer 'amdgpu' driver. Are there other kernel parameters that I should try? I looked around but I haven't found a good reference for all of the options. Any help is greatly appreciated. Thanks!
