I'm using Ubuntu 20.04.2 LTS Laptop DELL G3 3500 Graphics card: NVIDIA Corporation / GeForce GTX 1650 Ti/PCIe/SSE2 (from system settings)
I've used to connect my second monitor using type-c displayport, but it seems not to detect it anymore.
Tried to install and reinstall NVIDIA drivers versions 390, 435, 440, 450, 460, 465. Updated and reinstalled displaylink driver. Secure boot is disabled in BIOS. Tried different prime profiles for NVIDIA.

DP-1-1 disconnected (normal left inverted right x axis y axis)
HDMI-1-1 disconnected (normal left inverted right x axis y axis)
DP-1-1 seems to be like there should be connected via type-c monitor. Type C cable is working, monitor too, tested on another laptops.
When I connect another monitor to my laptop using HDMI - it works, when I connect it using type-c=>type-c (displayport) cable - it does not work.
Laptop like does not react any way on type-c monitor connected. Type-c in laptop is working, when I connect a type-c hub with connected ethernet cable, headphones, keyboard, mouse and monitor - everything works except a monitor wich is connected via HDMI to the hub.
Tried also all another found solutions from different threads - it doesn't help :(
Previously some time ago I used to connect the same monitor to the same laptop using type-c and it used to work nice.
