In Settings/displays is “Join” or “Mirror” selected? “Mirror” will remove the picture of the second display (since both displays show the same thing). Also, under Wayland with Nvidia video, you’d need the 565 Nvidia driver from the graphics-drivers PPA to get “Join” to work right.

Hello @bashn,

Question for you that I’m curious.
Where you using HDMI, DisplayPort, or Type-C and did you re-plug it to see it fixes an issues, if that fails, try relaunch that settings to see problem solved.

For Type-C display, my Acer Nitro 5 used to support Type-C as a display and back in last year’s December (December 2024), it’s no longer capable of being used as a display for certain monitors with Type-C display. If it has HDMI or DisplayPort, try one of them to see that solve issues for you.

I hope this solve issues for you, plus, ZenBook shouldn’t have Type-C slot available but it should have HDMI. I’m not making you have to do it, if you want to test that, that’s your choice (Especially for my curiosity). So that way I’m not wasting your time, stay tuned.

Your device is probably called ASUS Zenbook S 16 OLED UM5606WA which it has a maximum resolution around 3K resolution (2880x1800) at 120Hz of Framerate, and I can see yours is only at 60Hz rather than 120Hz maximum which I’m not sure why.

I have both cables USB to c-type or c-type to c-type given while getting the screen. It worked for previous installation, works perfectly for windows with same port.

The error message in the screen is :
Your device does not support DP Alt mode. Please install the latest driver and try again.

Well, that’s a shame.

Did you update an AMD Graphics driver?
If so, then reboot Ubuntu to see if that solved issues.

If that fails, try this command on a terminal.

sudo ubuntu-drivers autoinstall
