Ubuntu 21.04: could not insert 'evdi': Exec format error

[max1]

Hello,

I am having a similar issue with my Dell D6000 that uses DisplayLink on Pop OS 21.4....
I get the 5.4 driver for ubuntu instaled just fine and I can get 2 monitors through the dock to work up until I change one of their orientations then the system crashes.. or sometimes they do not connect at all and the system crashes right away.

Any headway with your issue?

Thank You!

I installed "DisplayLink USB Graphics Software for Ubuntu5.4-EXE.zip"
It seems the evdi module is not loaded by the kernel.

I see the following errors in syslog:

Some details about my configuration:

uname -a

If you need more details, I'll be happy to provide them.

I've now created an issue in the evdi project:
see https://github.com/DisplayLink/evdi/issues/301

Problem is fixed. Kernel 5.11.0-31-generic is now available and works as expected.
