Hi,

I have a fresh install of Fedora 38, I’m using a Lenovo ThinkPad X14s Gen 4, and I’m using a ThinkPad Universal Thunderbolt 4 docking station. I have three external monitors, two 1440p, and one 1080p. They are detected by Fedora, and I can change their placement and resolution sizes from the settings in Fedora. I got one of the screens to work when I changed the resolution to very low. I haven’t installed any extra drivers, but I’ve seen mentioned the DisplayLink driver, but just for Ubuntu. Has anyone got any ideas?

More info needed to see what may be occurring.

  1. Please post the output of inxi -Fzxx so we may see the hardware config and driver info.
  2. Please post the output of lspci -nnk (only the portions showing the graphics and docking station)
  3. There have been several issues with multiple monitors attached to a docking station. We need to work through all the details to identify the cause.
    Most often it seems the docking station may be blocking the PC receiving the edid data from the monitors so they never get properly configured.

I got the same problem with x395, But the same dock and monitors works fine with a Thinkpad T14, both with updated Fedora 38.
