Add a second GPU to working 15.2, ksplashqml crashes

English Install/Boot/Login

System is 15.2 running a Ryzen3700x on an Asus x570 MB with a MSI Nvidia 1660 super GPU in pci-e slot one. Boots/runs perfectly.

I added a second GPU, MSI Nvidia 1050 Ti to pci-e slot two with nothing connected to it. ksplash crashes with the following:

Will also say that there was no kde desktop just a bash and browser window that were open when I shut down to install the card. I was able to use bash to “sudo shutdown now” to turn the pc off.

I shut down and removed the second card and 15.2 boots up again fine. I suspect I need to add something to Grub?

Any thoughts?

Have you disabled the GPU on the CPU???

Two NVIDA should work but throw an AMD into the mix and all bets are off.

Hi
Could be a BIOS setting to select a specific card…?

Intel (primary)+2 x Nvidia for offload, Leap 15.3;

No issues on my Tumbleweed system when add an additional Nvidia gpu primary is AMD, offload Nvidia 1030, but did have a GT710 in it as well.

Neither systems have a nvidia xorg file created or present.

OP’s CPU has no builtin graphics: https://www.amd.com/en/products/cpu/amd-ryzen-7-3700x

Boot into command prompt and reinstall Nvidia drivers.

You don’t mention if you’re using Wayland or X.Org.

Leap 15.3 –

 > plasmashell --version
plasmashell 5.18.6
 >

Therefore, Wayland and any Leap, forget it.

  • Meaning forget about anything to do with multiple GPUs – for the moment …
