Hi, I pulled my test system out of storage this past weekend, and after working out how to get it to update KDE Linux, the system booted up, and my graphics driver had changed from Intel to llvmpipe.
The laptop:
Operating System: KDE Linux 2026-05-03
KDE Plasma Version: 6.6.80
KDE Frameworks Version: 6.27.0
Qt Version: 6.11.0
Kernel Version: 7.0.3-zen1-1-zen (64-bit)
Graphics Platform: Wayland
Processors: 4 × Intel® Core™ i3-2370M CPU @ 2.40GHz
Memory: 8 GiB of RAM (7.6 GiB usable)
Graphics Processor: llvmpipe
Manufacturer: Dell Inc.
Product Name: Inspiron 3520
From the beginning:
I had left this machine off for about 3 months or so, and when I went to update the system, I was getting the input/output known issue even after waiting an hour or two. (All of the Flatpaks updated without issue).
I did try at least one reboot here.
Following the solution from here: KDE Linux not pulling down the latest updates. Verbose output of updatectl update posted I was able to get the system manually updated using the commandline options from the KDE Linux docs: Keep the System Up to Date - KDE Community .
Upon a reboot, I found out that my machine was no longer using the Intel graphics driver, but rather llvmpipe.
I don’t think this is supposed to happen.
Let me know what logs might be needed to figure out what’s going on.
Interesting problem. That’s quite an old Intel CPU (Sandy Bridge? 15 years old?); I wonder if an update to the kernel or Mesa accidentally or intentionally dropped or reduced support for it.
Or, oh! Here’s an idea! We actually use Vulkan for the code to detect GPUs in Info Center (not 100% sure why, it’s pretty complex), so maybe that old CPU generation is no longer supported for Vulkan. This seems more likely, now that I think about it.
@sitter may know more.
What’s the output of
/usr/lib/kinfocenter-vulkan-helper
and
/usr/lib/kinfocenter-opengl-helper
And for the 3rd or 4th time this bug is back again… (maybe)
I checked it against my current version, and the version I upgraded from.

Let me know if you need anything else here.
