Hi,
I receive the following message when I connect my monitor.
"Your device does not support DP Alt mode, please install the latest driver and try again."
My OS is Kubuntu 18.04 , kernel 5.0 (but first I tried with 4.15 had the same result, upgraded kernel and then uninstall and installed the DisplayLink driver)
I will attach the zip exported by the DLSupportTool in the hope that someone can help me with this !
Thank you in advance !
Later update : I've tested the configuration (same laptop & monitor) with windows 10 and it works OK after installing DisplayLink Driver.
I can only conclude that it is a problem of the linux driver implementation...
