DisplayLink Forum - View Single Post - Displaylink not working in linux-5.4.26 (Realtime kernel)

I just tried to install the DisplayLink drivers on a Ubuntu 18.04 pc that uses a realtime kernel (5.4.26-rt17) to control a robot. After 20 minutes, however, the installation still is at the `Building EVDI kernel module with DKMS` step. I think this is caused because the display drivers are incompatible with the realtime kernel patch. I could, however, not find anything about the DisplayLink drivers and realtime/low latency kernels in the documentation (https://support.displaylink.com/know...rticles/684649). My question is, therefore, is it possible to use the DisplayLink and consequently a second monitor when using a realtime/low latency kernel?

Thanks a lot in advance
