Morning Kommunity,

Since the beginning I'm using KaOS, I've got the following trouble : When I connect my laptop to my télévision, the main screen (my laptop) freeze. I also can take a window and move it to the TV's screen, but when I move the mouse on the main screen nothing appeared (it's not black, just a freeze of the desktop, like screenshot - if I can say that) but I notice that where I'm clicking on something, something is done.
So, I only use the "synchronize output".
My poor english language doesn't help me to do a better explaination. I apologize.

To summarize :
- Laptop doesn't freeze, only the main screen
- On the freeze screen I can do everything without seen what I make
- Second screen works well

I don't where I can add specific information.

Thank you for reading,

Best note what graphics is in use plus get the Xorg log:

inxi -G

Xorg log:

Ok thanks, here is :

Inxi -G

Xorg.O.log is HERE

Do you need something else ?

The external monitor, does it connect to the Nvidia (discrete) card?
Start with installing nouveau:

sudo pacman -Syu
sudo pacman -S xf86-video-nouveau

Also check the PRIME section, see if that helps for this setup:

In this one the external monitor is connected to the only hdmi port. I don't know if it's connected to Nvidia card.

Thank you for the link, I'll check it ASAP (time to sleep in France :-) ).
