Default Dell XPS 15 not usable when switching off the lid display

Hi,

My setup is the following:

One displayLink docking station, with thow screen hooked in DVI/HDMI.
My laptop is an old Dell XPS 9550, running only on the intel card.

When I do:

xrandr --output eDP-1 --primary --mode 3840x2160 --pos 1920x0 --rotate normal --output DP-1 --off --output HDMI-1 --off --output DP-2 --off --output HDMI-2 --off --output DVI-I-2-2 --off --output DVI-I-1-1 --mode 1920x1200 --pos 0x0 --rotate normal

It's working good, but What I really want is when I connect my docking, I want to stop the lid screen, (eDP-1) and start my two external screen. I'm doing test only with one screen for now, so when running this:

xrandr --output eDP-1 --off --output DP-1 --off --output HDMI-1 --off --output DP-2 --off --output HDMI-2 --off --output DVI-I-2-2 --off --output DVI-I-1-1 --primary --mode 1920x1200 --pos 0x0 --rotate normal

To stop the internal laptop screen, then everything start to be lagging as hell, but there is not spike of CPU or RAM, but for example when I type at the keyboard, I get like on caracter each 2-3 seconds. When running again the first command, everything goes back to normal. Thats crazy...

Latest driver displaylink and latest EVDI driver as well. Kernel is: 5.5.13-arch1-1 #1 SMP IOMMU is on
