Comment 19 for bug 1615734

After doing a bit more investigation, I found that the older Lenovo W541's dock has a similar MST chip inside (it populates DFP-1.1 and DFP-1.2, as opposed to our DFP-3.1 and DFP-3.2). However, it doesn't have the same issues that we have with the P50. One of my co-workers has a similar set-up as me with a W541, so if there's any information from there that would be useful for comparison, I can try to provide it.

I've also tried XFCE as others have said before, and it was able to use all monitors fine, with the one weird quirk that it seemed like it detected the new monitors several times when I docked while logged in. It's just a bit too minimal for me, and I've gotten used to the nicities that GNOME or Unity provide.
