Hello everyone,
I run Manjaro on my work laptop. My desktop environment is xfce and the laptop has dual GPU (Intel/Nvidia). Here is the output of inxi:

I always use an external monitor which is connected to the laptop via HDMI. Since this morning, the monitor is not recognized anymore. I have tried several HDMI cables and monitors, but to no effect: screens can’t pick up any signal from my laptop.
I started by checking the latest updates I ran with pacman, suspecting that something might have been changed after reboot. But the latest update was several days (and reboots) ago, involving no kernel or graphic driver.
I also checked that the HDMI port was indeed detected with xrandr:

After reading a few topics on the forum, I am starting to think that my dual graphics installation might be problematic. Notably, you can see in inxi that the Nvidia card says it has no driver (only an alternate). I am not sure if this is normal.
Any idea what might be the problem? I would appreciate any guidance 
Thanks for your time!
