Default DL stopped working after Ubuntu 17.10 upgrade

DisplayLink was working just fine with Ubuntu 16.04, D3100, and two monitors (in addition to the laptop display). I upgraded to the latest DL a few months ago, but I forget what version that was. Last evening, I upgraded to Ubuntu 17.10 and experienced the "Ubuntu login loop." I uninstalled DL, and was then able to log in via lightdm. Next, I downloaded and installed DL 4.1.9, but my two monitors are always black.

I've tried unplugging monitors and docking station and plugging them back in. I tried unplugging docking station, rebooting Ubuntu, logging in, waiting a minute or so, and plugging docking station back in. None of this worked. Any idea how to get it working again?

UPDATE: I guess I haven't restarted my PC since I installed the latest DL when I first posted this two days ago. I just restarted it, and it turns out that I get the "Ubuntu login loop" with the new one, too. This is what happens: I no longer have the two external monitors plugged into the D3100. Instead, I have just one of them plugged into the (lone) HDMI port on my laptop. Has been working okay like that. I restarted, get the Ubuntu login screen, I enter my password, the screen goes blank, then I get the login screen again. This is different than the bad-password screen. The fix is to uninstall DL. I miss that third monitor.

Paul

Similar problem here. Working fine on zesty then did upgrade to 17.10 and after upgrading it first started flickering white in the corners on the login screen and if I tried to log in, it just kicked me back out. Then I upgraded the driver to the latest version and the displaylink monitor is black. Something shows up as DVI-I-1-1 with a max resolution of 720x576, but if I try to enable it, I get kicked out of the desktop. I've got it connected to a USB 2.0 KVM and it works fine on my windows boxes when I switch over.

I tried the intel workaround fixes and they were no help, but I'm running with a Radeon HD 4290 onboard.

I'm running kubutu 17.10 with plasma on a server with 64 bit AMD Phenom II with 4.13.0-32 kernel and Plasma 5.10.5, Kde frameworks 5.38.0 Qt 5.9.1 - all the latest base distibution for kubuntu.
