I pur hased a i-tec Universal 6x 4K/60Hz Display Docking Station + Power Delivery 140W without clue about what Linux compatibility means. Apparently it works with displayLink to get it working with displays.
As suggested under Need Help with DisplayLink I added evdi to kernelModules but I still have no singal. Any ideas?
I am using Gnome and Wayland so no Xserver.
Seems evdi does not exist. If I add it to boot.kernelModules the build fails with
modprobe: FATAL: Module evdi not found in directory /nix/store/b1g1sllmva5y8l2gm341916plmxmpjyx-linux-6.12.21-modules/lib/modules/6.12.21
I then installed displayLink driver but the issue stays the same: No display output
Here my current config:
boot = {
kernelPackages = pkgs.linuxPackages_6_12;
initrd = {
availableKernelModules = [
"xhci_pci"
"thunderbolt"
"nvme"
"usb_storage"
"usbhid"
"sd_mod"
];
kernelModules = [
"evdi"
];
....
extraModulePackages = [
# Add other modules here if you have any
config.boot.kernelPackages.evdi
];
};
# host-specific packages
environment.systemPackages = with pkgs; [
displaylink # DisplayLink DL-7xxx, DL-6xxx, DL-5xxx, DL-41xx and DL-3x00 Driver for Linux
];
I see the module is loaded
lsmod | grep evdi
evdi 135168 0
But I also see errors on boot
