EVDI service version: /sys/devices/evdi/version not found

[jotapikie]

Hey! I already tried multiple ways to install the evdi kernel but none of them worked. I kindly ask for your support to help me with this problem. I attached the installation output and --debug output for easy reading. There is an error on line 86 of the installation output. I am also attaching the /var/lib/dkms/evdi/1.13.1/build/make.log. Any additional information just ask. Thanks in advance. debug.txt installation_output.txt make.log

Same issue on my part, I posted an issue right before you (issue #825, yours is #826).

This is probably due to an error when building evdi, see #821 I think this should be closed as duplicate

I got the same issue on kernel 6.3.0-kali1-amd64. I managed to narrow it down to a missing i915 kernel module.

I waited for a bit and now thanks to the addition of this module to the rolling distro, I was able to sudo apt install evdi-dkms, reinstall displaylink-debian and change /etc/X11/xorg.conf.d/20-displaylink.conf like mentioned here.

Carefull tho, I had an instance where I got a kernel panic not syncing vfs after a bad update by installing evdi-dkms myself. I had to load in recovery to uninstall displaylink-driver, sudo apt clean, sudo update-initramfs -u -k 6.3.0-kali1-amd64 and reboot.
