Random display failures

[dan_linder]

So, I'm probably tempting fate here but I might have stumbled across a fix documented at the Arch Linux wiki page for DisplayLink.

https://wiki.archlinux.org/index.php/DisplayLink

Scroll down to this section of that page "USB 3.0 DL-6xxx, DL-5xxx, DL-41xx, DL-3xxx Devices" and add the

/usr/share/X11/xorg.conf.d/20-evdidevice.conf

file and add these lines:

Section "OutputClass"
	Identifier "DisplayLink"
	MatchDriver "evdi"
	Driver "modesetting"
	Option  "AccelMethod" "none"
EndSection

So far, my Spectre x360 with a Dell D6000 dock has been stable in a multi-screen setup overnight whereas it would "forget" the displays in less than 15 minutes.

I'll continue testing - I hope this helps others.
