No displayport over USBC with lenovo ideapad gaming 3 (15IHU6)

Displayport over USBC on linux not recognized I am using archlinux on the Lenovo Ideapad Gaming 3 15IHU6, I cannot get a display to react to the usbc port connection. USBC-USBC is recognized as a "USB billboard device" USBC-DP(mini) is recognized as a "Displayport Alt mode" Neither display any image, neither in X or outside. (My previous laptop - a Tuxedo Computers one) displayed console on all screens attached at boot time). --- **drivers in use:** nvidia_drm 126976 2 nvidia_uvm 6717440 0 nvidia_modeset 1650688 1 nvidia_drm nvidia 72564736 2 nvidia_uvm,nvidia_modeset video 81920 4 ideapad_laptop,xe,i915,nvidia_modeset ideapad_laptop 69632 0 platform_profile 12288 1 ideapad_laptop rfkill 40960 5 iwlmvm,bluetooth,ideapad_laptop,cfg80211 sparse_keymap 12288 2 intel_hid,ideapad_laptop video 81920 4 ideapad_laptop,xe,i915,nvidia_modeset i8042 57344 1 ideapad_laptop wmi 32768 3 video,wmi_bmof,ideapad_laptop $ pacman -Ss nvidia | grep -i installed -A1 extra/egl-wayland 4:1.1.16-1 [installed] EGLStream-based Wayland external platform -- extra/libvdpau 1.5-3 [installed] Nvidia VDPAU library extra/libxnvctrl 560.35.03-1 [installed] NVIDIA NV-CONTROL X extension -- extra/nvidia 560.35.03-3 [installed] NVIDIA drivers for linux -- extra/nvidia-settings 560.35.03-1 [installed] Tool for configuring the NVIDIA graphics driver extra/nvidia-utils 560.35.03-2 [installed] NVIDIA drivers utilities -- extra/vulkan-nouveau 1:24.2.2-1 [installed] Open-source Vulkan driver for Nvidia GPUs extra/xf86-video-nouveau 1.0.17-3 (xorg-drivers) [installed] Open Source 3D acceleration driver for nVidia cards mkinitio.conf: HOOKS=(base udev autodetect microcode modconf keyboard keymap consolefont block filesystems fsck) MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm) **devices:** $ sudo lshw -C display *-display description: VGA compatible controller product: TigerLake-LP GT2 [Iris Xe Graphics] vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 logical name: /dev/fb0 version: 03 width: 64 bits clock: 33MHz capabilities: pciexpress msi pm vga_controller bus_master cap_list rom fb configuration: depth=32 driver=i915 latency=0 mode=1920x1080 resolution=1920,1080 visual=truecolor xres=1920 yres=1080 resources: iomemory:610-60f iomemory:400-3ff irq:183 memory:6104000000-6104ffffff memory:4000000000-400fffffff ioport:5000(size=64) memory:c0000-dffff memory:4010000000-4016ffffff memory:4020000000-40ffffffff *-display description: 3D controller product: GA107M [GeForce RTX 3050 Mobile] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list rom configuration: driver=nvidia latency=0 resources: iomemory:600-5ff iomemory:610-60f irq:184 memory:54000000-54ffffff memory:6000000000-60ffffffff memory:6100000000-6101ffffff ioport:4000(size=128) **X setup:** $ xrandr [...] DP-1 disconnected (normal left inverted right x axis y axis) HDMI-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 196mm 3840x2160 60.00 50.00 59.94 30.00 25.00 24.00 29.97 23.98 30.00 1920x1080 60.00 60.00 50.00 59.94 30.00 25.00 24.00 29.97 23.98* 1400x1050 59.95 1280x1024 60.02 1440x900 59.90 1280x960 60.00 1280x720 60.00 50.00 30.00 25.00 59.94 29.97 24.00 23.98 1024x768 60.00 800x600 60.32 720x480 60.00 59.94 640x480 60.00 59.94 DP-2 disconnected (normal left inverted right x axis y axis) DP-3 disconnected (normal left inverted right x axis y axis) $ cat /etc/X11/xorg.conf Section "Device" Identifier "Device0" Driver "modesetting" VendorName "Intel Corporation" BusID "PCI:0:2:0" EndSection Section "Device" Identifier "Device1" Driver "nvidia" VendorName "NVIDIA Corporation" BusID "PCI:1:0:0" EndSection
