Bug dual screen KDE - GTX1050

Good evening friends,

First of all sorry for my english ^^

I wanted some help with running my pc under KDE.
Since last update … unable to dual screen computer.
Here are the GPUs:
OpenGL renderer string: Mesa Intel® UHD Graphics 630 (CFL GT2)
OpenGL renderer string: GeForce GTX 1050/PCIe/SSE2

I have the impression that the rendering goes through the intel and not the nvdia.
How to solve the problem ?

Thanks for your help

Please post the output of inxi -Gazy and xrandr --listproviders.

thank you for your quick help
here is the info

The second display is not currently connected. But I can do it when needed

And uname -r?


Please post the output of head -n999 /usr/share/xorg.conf.d/* and mhwd -li as well.

I don’t have xorg.conf.d folder

i don’t know if it can help

This issue seems to be exactly the same as this one. The simplest workaround to use the 5.9 kernel until the newer NVIDIA drivers reach the stable repositories.

Can you post the output of pacman -Qs nvidia?

The update removed me precisely 5.9.16 for incompatibility … And I retested on 5.4.85 but without success

Can you boot into Linux 5.4, and post the output of inxi -Gazy and xrandr --listproviders from there as well?

I made a typo, the fixed command: head -n999 /usr/share/X11/xorg.conf.d/*. Please post its output as well as the output of head -n999 /etc/X11/xorg.conf.d/*.

Good news, it works fine in 5.4 :).
I just reset nvdia-prime.

I go back to 5.10, to place your order and test your order again

If you want 5.10 kernel,need to wait for the next stable release with the new kernel 5.10.7 and the nvidia driver 460,both version fix the dual screen issue.

Well, then you need to wait until the next NVIDIA update and you can continue using Linux 5.10.

As long as the pc is functional.
No problem.
thank you
