Hi,
I've installed Archlinux on a Dell Precision 7540
I've encountered two errors one are several errors during boot that I can't make sense out of it:
Mär 13 08:04:27 whites-nb5 kernel: i915 0000:00:02.0: [drm] *ERROR* Failed to probe lspcon

Mär 13 08:04:27 whites-nb5 kernel: i915 0000:00:02.0: [drm] *ERROR* LSPCON init failed on port DAnd the second problem is that the Laptop is working smooth but when I start a new application the mouse cursor is stuttering for a few seconds.
I'm using KDE Plasma as Desktop environment.
