I have Fujitsu Port Replicator PR08 that I like to use with my Zorin Laptop. But both connected screens are black.
What driver do I need?
Zorin 17.3, will update to 18 soon
Hi and welcome. Zorin 17 is a fork of Ubuntu 22.04, so:
" The issue of both screens connected to the Fujitsu Port Replicator PR08 appearing black on Ubuntu 22.04 may stem from several potential causes, including driver compatibility, kernel support, or configuration issues. While the PR08 is designed to support multiple users with saved desktop configurations, the display output functionality depends on proper hardware and software integration.
First, ensure that the DisplayLink driver is correctly installed and compatible with Ubuntu 22.04. The DisplayLink driver is required for most USB-C docking stations to enable video output, and outdated or improperly installed drivers can result in blank screens. Verify that the DisplayLink device is recognized on the USB bus using the lsusb -d 17e9: command, as all DisplayLink devices have a vendor ID of 17e9. If no device appears, check the USB cable, port, and power supply, and try connecting the dock to another computer to rule out hardware failure.
Kernel-level support for USB-C alternate modes, such as DisplayPort over USB-C (DP Alt Mode), is essential. The typec_displayport kernel module must be loaded, and the TYPEC_DP_ALTMODE configuration should be enabled in the kernel. If the system does not detect the display ports, check the output of tail /sys/bus/typec/devices/*/displayport/configuration to confirm whether the display mode is properly configured. If no such file exists, the USB-C port may not be negotiating DP Alt Mode correctly.
Additionally, some users have reported that connecting the port replicator to a USB 3.1 port can introduce instability due to immature drivers, so ensure that the USB host controller drivers are up to date. If the issue persists, consider testing with a different USB port or cable, and verify that the monitors are properly powered and set to the correct input source.
Finally, while the Fujitsu PR09 is explicitly mentioned in some forums as working with Linux when properly configured, the PR08 may have similar requirements. If the PR08 is not recognized as a DisplayLink device, it may not support video output under Linux, or the necessary drivers may not be available. In such cases, the lack of official Linux support from Fujitsu may limit troubleshooting options.

Welcome to the Forum!
So, when I understand that right, this Device is some kind of Docking Station. Do the Screens without this work correctly? I ask to make sure that it isn't a Screen Issue. Do the Cables sitting right and connected to the right Ports? Did You tried other Cables?
The screens and everything works with a windows laptop via usb
I will try to test the AI tips above
