When I unplug and replug it, sometimes the screen will freeze and I have to force reboot. log shows: i915 0000:00:02.0: [drm] *ERROR* mstb 00000000c152fe9e port 1: DPCD read on addr 0x4b0 for 1 bytes NAKed i915 0000:00:02.0: [drm] *ERROR* mstb 00000000c152fe9e port 2: DPCD read on addr 0x4b0 for 1 bytes NAKed The machine also dies when resuming from suspend with the adapter plugged i= n, but I could not get any log, just guessing it might be the same issue. my setup: HP Envy 13 ad110tu (i5-8250U, UHD 620) Archlinux with kernel 5.16.13-arch1-1 x86_64, KDE Plasma 5.24.3 on Wayland --=20 You may reply to this email to add a comment.
