Manually signing DL driver in UEFI

Thank you. I must confess that I am unable to make heads or tails of the "Ask Ubuntu" article posted under "Option 3: Sign evdi kernel module manually," hence I would appreciate if you could offer some guidance vis-a-vis the manual signing of the driver.

Perhaps a bit late and you have probably fixed it, but you can reinstall the evdi-dkms using:

sudo apt-get reinstall evdi-dkms

I hope that helps. It did for me! But it is actu1ally a reset of option 1 in https://support.displaylink.com/know...-with-uefi-sec
