I run dual Nvidia dedicated Nvidia GPUs. I finally got Plasma 6.3 working after the update to 6.3.1, but I now see an odd entry in Info Centre for a third GPU running llvmpipe (which I assume is nouveau).
I have
GPU1- Nvidia discrete
GPU2- Nvidia discrete
GPU3- LLVMPIPE
What is the GPU3? I do not have an IGPU on the CPU, only the two discrete graphics cards. I do not think there is anything else on the system that might be confused for a graphics processor. So far it seems to be benign.
Hi - can you post the full details from that Info Center screen? Is it possible that you have an integrated GPU on your CPU - even if you aren’t using it - and that it’s perhaps missing some drivers that would be necessary if it were in use?
Just for example, I’m on a desktop with an NVIDIA card, nothing hooked up to the motherboard’s graphics ports, but there’s still an entry for the built-in graphics capabilities of my CPU:
Operating System: Fedora Linux 41
KDE Plasma Version: 6.3.1
KDE Frameworks Version: 6.11.0
Qt Version: 6.8.2
Kernel Version: 6.12.15-200.fc41.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 16 Ă— AMD Ryzen 7 7800X3D 8-Core Processor
Memory: 30.4 GiB of RAM
Graphics Processor 1: NVIDIA GeForce RTX 4070 SUPER
Graphics Processor 2: AMD Radeon Graphics
Manufacturer: Micro-Star International Co., Ltd.
Product Name: MS-7D78
System Version: 1.0
I forgot to mention this is in X11, not Wayland. It does not appear to be the same issue as this bug. GLX info shows everything working as expected. It is not showing the software renderer. Vulkan is working correctly and not crashing like in the bug.
After digging into this a bit, by all appearances this seems to be limited to Info Center. Neither hardinfo2 nor neofetch show the issue (but curiously neofetch crashed plasmashell).
I have seen the lvvmpipe entry in Wayland, but assumed it was related to the x11 to wayland bridge which would be entirely unnecessary in X11. I am guessing my assumption may be wrong.
I do not have an iGPU (Ryzen X) though my mobo does support one. My output is pretty much identical to yours with the exception that GP2 is Nvidia not AMD, and there is now a GP3 for lvvmpipe. Graphics Procesor 1 and 2 show “- discrete” in the tag as well. This is a desktop PC, not a laptop if that makes any difference.
Thanks - yeah, as @ninjalj mentioned, even if there is no actual “integrated GPU” in your CPU, software rendering using the CPU is always a possibility for outputting graphics (as painful as it would be!) - which sounds like it would fall back to LLVMpipe in this case.
Maybe “processor” is too literal of a word to be used here? I don’t know if “device” would be any better in that respect, but I think the intent there is basically to list out the ways that graphics can be rendered and presented to your screen?
That seems likely. It may have always been “present” in the background but is now showing up in info center, which, reading over the change log, it seems adding more detail within info center was one of the things mentioned.
