I bought a new laptop and use external ssd to run manjaro. Default OS on the laptop is Windows and its works fine with my two monitors.
Same manjaro on the same ssd also worked fine on my old laptop with the same two monitors.

Hi @bibiba,

This is probably why. Please provide the output of:

OK,

According to your inxi output, you have an AMD and Nvidia card:

Yet, the hybrid driver isn’t installed:

But luckily it’s available:

So install that one:

sudo mhwd --install pci video-hybrid-amd-nvidia-prime

Reboot, and see if it worked.

Hope it helps!

Thank you.

I tried sudo mhwd --install pci video-hybrid-amd-nvidia-prime, but it failed:

error: target not found: linux65-nvidia
Error: pacman failed!
Error: script failed!

Then I update my kernel from 6.5 to 6.8 in the Manjaro Settings Manager and reboot.
Now everything works

Hi @bibiba and welcome to the Manjaro community.

Kernel 6.5 has been EOL for some time. This should have been attended to much earlier to avoid issues like this. Nonetheless, I’m glad you resolved it/

As a new user, please take some time to familiarise yourself with Forum requirements; in particular, the many ways to use the forum to your benefit. To that end, some or all these links will be invaluable:

And last, but not least, the Stable Update Announcements, which you should check frequently for important update related information. Occasionally an issue might be directly related to a particular update; it’s always best to check those announcements.

Cheers.
