I can get two monitors to work with display port additionally to the laptop.

However, I'm experiencing random system freezes. Randomly, the whole system just stops, I can't see if there is any relation with what I'm doing. The only way to get the system back is a hard shutdown.

Any ideas on how to diagnose this?

For me, I would see the DisplayLink connected screens freeze and then I would unplug via usb and plug back in again, and then I'd have to run an alias which I've created from ARandR to fix my screen layout.

What I've found is that this always happend earlier in the day and it was happening when the network was very busy (backups being uploaded to the NAS). Since I've switched to plugging in the network cable directly into my machine that has resolved this issue for me. I don't particularly use the USB ports on my device, but I suspect heavy USB port usage could also have a similar impact.
