Hi,
A once speedy pc has now become sluggish and I don’t know where to start: boot takes more time than usual, Plasma loads but then makes me wait a lot for panels and the desktop to appear, the UX is at times responsive and at times is not. I’m looking for some advice on what to use or look for to troubleshoot the matter.
Specifics:
- Operating System: Fedora Linux 43
- KDE Plasma Version: 6.5.3
- KDE Frameworks Version: 6.20.0
- Qt Version: 6.10.1
- Kernel Version: 6.17.10-300.fc43.x86_64 (64-bit)
- Graphics Platform: Wayland
- Processors: 4 × Intel® Core™ i5-2400 CPU @ 3.10GHz
- Memory: 16 GiB of RAM (15.4 GiB usable)
- Graphics Processor: llvmpipe
- Manufacturer: LENOVO
- Product Name: 7052A9G
- System Version: ThinkCentre M91p
Notably, I struggled on installing Linux on this hardware for a long time: after installation distros won’t boot properly. I found that the something may be very old and I needed to use MBR as partition table instead of GPT. But it has always been like this, and before the system was very snappy.
Something I did recently (but I think still before this performance degradation) was reinstalling MariaDB for Akonady, as I tried replacing it with MySQL for some reasons and than reverted back when I saw that Akonadi wasn’t working.
The situation becomes a little better after some time from the boot, but the only startup application is Nextcloud. Even then, System Monitor generally shows this situation, where only background jobs and Firefox consume memory:
Something interesting: the userspace now loads in a lot of time!
samuele@192:~$ systemd-analyze
Startup finished in 734ms (kernel) + 2.311s (initrd) + 3min 43.066s (userspace) = 3min 46.112s
graphical.target reached after 25.253s in userspace.
