I have a problem with external display connected to my laptop. It displays "no-signal" warning.
I use DELL G15 5520-6600 laptop with Dell P2419H display. I use XFCE.
Below is my GPU info
Code:
jan@jan:~$ lspci | grep VGA
0000:00:02.0 VGA compatible controller: Intel Corporation Alder Lake-P Integrated Graphics Controller (rev 0c)
0000:01:00.0 VGA compatible controller: NVIDIA Corporation GA107BM [GeForce RTX 3050 Mobile] (rev a1)
nvidia-detect has suggested me to install nvidia-driver, but I got problems (after installation)
Code:
jan@jan:~$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running
I think my GPU supports optimus, but I'm not entirely sure. I have a problem with this site:
https://www.nvidia.com/en-us/geforce...upported-gpus/
I tried to install bumblebee like that.
Code:
sudo apt install bumblebee-nvidia primus-nvidia primus-vk-nvidia
Also below is my xrandr ouput:

I don't know how to read it... Is my external display detected or not?
Thanks for your help in advance!
