Drivers stop working after a kernel upgrade, need reinstall

No, it's not working, that's why I wanted to make you guys aware to see if this can be corrected in future versions.

It's very easy to test it by installing simply installing an old kernel version, installing the driver and then trying to upgrade the kernel and then trying to use the dock. Actually, the dock works (USB connections and networking) but displays won't even turn on unless you reinstall the driver again.

More information on this matter:

I have 2 different devices, one at home and one at the office, both of them use DisplayLink. I did a kernel upgrade last night and of course, it made my device at home to not work so I had to uninstall the driver, reboot, reinstall the driver and reboot again to make it work.

Then I came to office Today and when I plugged to my USB dock it didn't work, so I had to once again: uninstall, reboot, install, reboot. Not only is annoying but this means that it even affects devices! So, you basically will have to uninstall and reinstall per each device you have.

Very weird and annoying, I hope this can get fixed in any way.

Basically every time I update the kernel, I have to
* displaylink-installer uninstall
* reboot
* ./displaylink-driver-5.2.14.run

I'm on Ubuntu 18.04.2 LTS. I hadn't noticed a problem with the 4.4 driver.

I just upgraded to the 5.2 driver; I'll keep an eye out for issues.

After the update to kernel 4.15.0-58, I had to uninstall, reboot then install again.

After installing last version, now when I update Kernel, on the next reboot it takes around 3 - 4 minutes for the dock to recognize the external screens and work. It will work without installation but not immediately.

It will work normally afterwards on the very next reboots though.

I'm happy to be able to write that I haven't had to do that any more for a while now after kernel updates.
