3 monitors not working with mint 19 on xps #238

Hi,

I've looked through the troubleshooting guide/post install guide and had no luck. I'm running linux mint 19 on a XPS 9575-735 which I believe has a Radeon RX Vega M graphics card.

At first, the setup was working after a few reboots and I was able to use all three montiors.

I've tried flipping displays on and off using the display application in mint but no dice. One monitor works fine but the one that is not plugged into the "4K HDMI" port will show a distorted display. It shows horziontal bars of the desktop background. If I screenshot it, the display will look fine.

Here is my debug output..

I should also mention, the affected monitor is listed as DVI for some reason in display. Both are plugged into HDMI ports from HDMI ports.

What would happen if you did what I suggested here: https://github.com/AdnanHodzic/displaylink-debian/issues/228#issuecomment-467889348

Just had some luck. I think my linux kernel or headers or something were out of date.

I updated my linux-headers packages with ukuu to the latest, reinstalled and now all three monitors are working fine.

Some minor cursor flickering but I can deal with that.
