I am running an HP Zbook 15 G5 at work and am working on transitioning from using the new Macbooks with Touchbar to this with Ubuntu 18.04.3 with HWE packages installed. When connecting this machine to an Apple Cinema Display (27") using the Apple-Thunderbolt-2-to-USB-C adapter sold by them, it seems the monitor only works on waking from sleep, with an incorrect resolution. Otherwise, when I hotplug it while the laptop is on, or keep it plugged in while powering on, it does not work.
Things I have tried:
- Disable Thunderbolt Preboot ACL in BIOS settings and enable
- Native mode + low-power for Thunderbolt in BIOS
- Legacy mode for Thunderbolt in BIOS
- reset BIOS to factory defaults, then re-enable legacy boot as our install requires
Here is the output from journalctl --follow when unplugging and replugging the display:
