also solves the problem
You can see in the git links where the original issues were reported and fixed:
https://gitlab.freedesktop.org/drm/intel/-/issues/3166
https://gitlab.freedesktop.org/drm/intel/-/issues/2801
Before these patches were added, it would take about 5-10 attempts to get multi-monitor working (replugging over and over again). Even after connected, 2-4 hours later the displays will randomly disconnect and I have to go through the cycle mentioned earlier. Sometimes the system overall would freeze and required a hard reboot, but that was more rare.
I'd say the workaround of moving your mouse to wake your display before unplugging your dock is a better workaround than overall breaking thunderbolt for most users by reverting the patches mentioned above.
Are there any other thunderbolt users with any feedback or opinions on this topic?
