If your connector has the Thunderbolt logo, then it’s Thunderbolt, if it has the DP logo then it’s not. Even then, the Thunderbolt component only controls enable/disable permissions and bandwidth partitioning. The graphics chip and DRM code does the rest of the work, and it sounds like the problems here are with those components. T495 has AMD Ryzen silicon, and AMD never associated Thunderbolt with its Ryzen platforms. The dock connector is just a USB-C. On dock removal, the devd events (system DRM, type HOTPLUG) are correctly generated and received by libudev-devd, but then for some reason UD_ACTION_HOTPLUG is not causing the X server to re-scan drm connectors and to re-configure them. Will dig further into the issue as I feel it should be easy to solve. > > Scott > AliReceived on Wed Dec 02 2020 - 06:00:15 UTC
