Well I'm assuming that the German is the same as my English version! :-) The only difference i have is that I am running kernel 5.4.0-29.generic...maybe try enabling the focal-proposed repository?

I hope so! :D Okay I will give it a try. Thanks

You could also try "sudo apt -f install" to fix any missing dependencies before re-running the installation...

Jeins 05-04-2020 01:34 PM

Tried that before. Don't help. And also with new kernel, I get the same error

Interesting...

I've done a "apt search libdrm" on my system for comparison. Output is as follows:

Working with new 20.04 DisplayLink driver
 
Only thing extra I had to do even though on Intel graphics I
had to make /usr/share/X11/xorg.conf.d/20-displaylink.conf
contain:
Section "Device"
Identifier "DisplayLink"
Driver "modesetting"
Option "PageFlip" "false"
EndSection

not this:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
EndSection

I needed this with the 5.2 driver, but not for the 5.3 one, which works with both X and Wayland...I'm using Intel HD 4600 graphics (builtin).

Now I have the same output, but that don't change anything.

Have you removed any previous installations, such as the displaylink-debian one, before trying the new installation? I removed all previous displaylink drivers and re-booted before trying the latest one...

Jeins 05-04-2020 03:24 PM

Yes. I used the displaylink uinstaller
