Lenovo Hybrid USB-C dock stopped working

[petakii]

After using Monitorian for a few months, it stopped working recently. I've been using it with 2 HP e242 monitors connected to a Lenovo Hybrid USB-C dock via HDMI and DisplayPort.

Previously it worked fine, now only shows my laptops built-in screen since the last restart. Updating to the latest version didn't help.

Could you read Contributing Guidelines and post probe.log and operation.log? How to produce these logs is explained in Reporting in readme.

operation.log can't be produced, it says "Wait for more information", Make a log is ticked, tried unplugging the monitors, rescanning, turning them on and off, nothing produces a log.

Probe.log contains the following:

probe.log

It seems like the app recognizes the screens, but can't control them.

Thank you for the probe.log. As for the operation.log, it literally means that you need to wait for this app to accumulate more information for meaningful result.

The probe.log shows that no external monitor which can be the target of DDC/CI is found. Perhaps your USB hub causes this issue. I guess something related to your hub changed.

Sadly for this app, an alternative app is working properly, the problem is not in the dock. Updated the dock firmware, still don't work. Operation.log still not produced anything.

Closing the issue, as it's resolved for me.
