NVIDIA detected no signal ASUS GU502L

Hi there!

I am posting my problem as I do not manage to solve it, trying to search for solutions

I have adquired a ASUS GU502L with NVIDIA RXT2060 and installed linux 20.04. Laptop screen works great but as soon as I wanted to connect a second HDMI screen, the screen is detected but not displaying anything

xrandr drops the following results

and the nvidia bug report is the following
nvidia-bug-report.log.gz (349.2 KB)

I have tried so many things that came up to need to reinstall ubuntu as no screen was working

Can anyone help me?

I would really appreciate

Does the monitor work in nvidia/performance mode?
sudo prime-select nvidia
and reboot.

No, it does not

Does it work when using nouveau?
Did you check the monitor and cable?

Monitor and cable working fine with macbook pro late 2011 Y

I asume nouveau is the natural mode of nvidia, the one before changing to performance. It was also not working. If this is not the case, how can I change to nouveau?

You can switch to it using Software&Updates application.

I have switched back to nouveau and it is still the same

nouveau 1998848 2
ttm 102400 1 nouveau
drm_kms_helper 217088 2 i915,nouveau
mxm_wmi 16384 1 nouveau

wmi 32768 5 intel_wmi_thunderbolt,asus_wmi,wmi_bmof,mxm_wmi,nouveau

Just for you to confirm nouveau is now on again

I have followed this instructions
