USB screen (ASUS MB168B+) no longer detected after latest Ubuntu update

Hello,

It seems that the command line used for disabling the secure boot mode was the following:
sudo mokutil --disable-validation
-asked for a password
- restart and during BIOS step ask to type any key for modification
- choose change secure boot state
- enter some characters of the password

On my machine it was sufficient to deactivate secure boot and nothing was necessary inside the BIOS parameters but it seems to be the case for others machines.

Moreover, if you do not want to deactivate the secure boot it should be possible to manually sign the display link drivers and add the signing key in the secure boot keys. Here are some hints on how it is possible:
