[FreeBSD 13] : KDE5/Plasma suddenly slows down ...

[didier]

Hi everybody,

I've installed a fresh FreeBSD 13 few days ago with KDE5.

kf5-kdeclarative-5.82.0
kf5-kded-5.82.0
kf5-kdelibs4support-5.82.0
kf5-kdesignerplugin-5.82.0
kf5-kdesu-5.82.0
kf5-kdewebkit-5.82.0
mkdesktop-5.0
plasma5-kde-cli-tools-5.22.4
plasma5-kde-gtk-config-5.22.4
plasma5-kdecoration-5.22.4
plasma5-kdeplasma-addons-5.22.4
plasma5-polkit-kde-agent-1-5.22.4

I was building a cross gcc in a chrooted environment with a nullfs mount of gcc src when the system became unresponsive unless moves of the pointer.
The system didn't seem to be hung considering HD operations.
This happens all the times.

Pressing the on/off button doesn't trigger instinction immediately but one or two minutes after.

I wonder if someone has encountered this kind of trouble.

I would like to investigate further. But I don't know how. Is there a log file for KDE5/Plasma ? I didn't see anything in /var/log.

No error in Xorg.0.log, just few warnings :

[I]        (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
[    22.268] (WW) `fonts.dir' not found (or not valid) in "/usr/local/share/fonts/misc/".

Never seen that on 12.2.

Very strange, isn't it ?

… all the times.

Not all the time.

I don't imagine an issue with KDE Plasma.

Can you describe your hardware?

Share the result of a probe, if you like. The first of these two commands is a one-off:

1. pkg install -y sysutils/hw-probe sysutils/lsblk sysutils/pciutils sysutils/usbutils
2. kldload fusefs && hw-probe -all -upload

Thank you, grahamperrin and sorry for disturbing.
It was a fresh fbsd 13 installation, so I've preferred to go back to freebsd 12.2.
And the trouble has disappeared.

I confirm this trouble does not occur in text mode. I've observed it with KDE on stage.

I observe the same behaviour with fbsd 12.2/KDE plasma 5.22.

I guess baloo could be the cause because the default didn't exist on my previous fbsd 12.2 while baloo had been disabled.
My guess a mounted nullfs device and baloo_file can't live together; I don't exclude it could occur a race condition.
