no longer working in clamshell mode after sleep

[pfeffer]

tl;dr: DisplayLink worked fine with clamshell mode until last update, help!

Details
My setup is thus:

1 Mac Mini M1
1 MacBook Air M1

Both of the above are connected to an MT-VIKI 8K60Hz bidirectional USB-C switch, which is itself connected to a WAVLINK Dual Display Docking Station. The hub has my two BenQ monitors connected via HDMI cables.

This has previously worked great for switching between computers seamlessly even with the Air closed, both computers on and in sleep mode. I select my computer with the switch, DisplayLink puts the login screen up, and I'm ready to work.

From the time I updated to the latest version of DisplayLink, however, it's not working like this anymore. For the Mini, nothing has changed, but for the Air, I have to open the computer up, login, open DisplayLink (even though it's set to open at log in), wait for it to recognise both of the monitors, and when I close the Air, I must again log in before I can proceed to work.

This is all mildly annoying and probably specific to my setup and likely Mac-related, but I wondered if anyone had some suggestion for getting DisplayLink to work in clamshell mode even while the computer is asleep?

Thanks mjaroch. I'm still having this issue and had not gotten around to following your instructions, as there's quite a few steps there. I did download and install and run the app to collect data, but unfortunately the link in "Send the debug file to DisplayLink support" does not work, and I'm not sure how to send the file. How do I contact support?

Meanwhile, looking at the thread you linked, it appears that this is a known bug, but oddly I did not experience it until recently despite using this since September 2024.
