- Are you using the latest driver?
yes - Are you using the latest EVDI version?
yes, 1.14.4 by install synaptics-repository-keyring.deb, using dkms to build evdi.ko - If you are using a DisplayLink device, have you checked 'troubleshooting'
on DisplayLink's website?
Yes, and my device is HP B005DS, it works well on x86 PC - Is this issue related to evdi/kernel?
Not sure, no error when modprobe evdi - Linux distribution and its version
debian GNU/linux 11 (bullseye) aarch64 - Linux kernel version
5.10.107 - Xorg version (if used)
xserver-xorg-core 2:1.20.11-1 arm64 - Desktop environment in use
xfce4
after cp evdi into /lib/modules/... then plugin USB cable, kernel log as follows:

There is a /dev/dri/card2 node file created, and under /var/log/dispalylink/, there is .edid files for the monitor, and log files, no readable part however.
I also tried selecting udl in drivers/gpu/drm/, but still no working.
And on another kernel 5.10.160 of rockchip, "modprobe evdi" always causes kernel NULL pointer issue, still no screen show, log as follows:
