Ubuntu 21.04: could not insert 'evdi': Exec format error
Hi all,
I'm not able to use my monitor via DisplayLink on Ubuntu 21.04. 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: Code:
Aug 4 18:48:25 mZBOX systemd[1]: displaylink-driver.service: Scheduled restart job, restart counter is at 357. Aug 4 18:48:25 mZBOX systemd[1]: Stopped DisplayLink Driver Service.

Please run the installer with uninstall param, this will get rid of the evdi you had installer previously:

Thanks for this hint. I tried this already several times, but it does not solve the problem.

ok, so if you still have another evdi loaded, can you make sure you do not have `evdi-dkms` installed and then repeat uninstall + install procedure?

This was one of my tests when I had the problem with DisplayLink: I installed evdi-dkms, but this also failed when I tried "modprobe evdi".
I removed evdi-dkms, but the problem with DisplayLink remains. Package status is not "installiert": Code:
mmehl@mZBOX:~$ apt list evdi-dkms Auflistung… Fertig evdi-dkms/hirsute,hirsute 1.9.1-1ubuntu1 all |

I know it is not helping but decided to post this anyway.
I have checked the same kernel you have installed and I can reproduce the same issue you have posted. So I'd say this is a bug that needs to be reported. |

Similar Issue
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! Quote:
