External monitor not working with ubuntu in Asus tuf f15


In my laptop [Asus tuf F15), which is equipped with a RTX3050, when I try to use an external monitor using the HDMI output, it is not recognized. Apparently, Ubuntu is using v510 drivers, and I’m pretty sure the secure boot is disabled. In Windows 10, the second monitor works perfectly.

I have changed the Grub linux command to pci=realloc
Still not working
Any ideas about how to solve it.

Many thanks

from dmesg output
So disable it ;-)

As a side note: Do not use the .run file installer. Especially don’t mix distro package installation and .run file installation.
