Yet ANother Baloo Problem - Baloo File Indexing has been disabled QStandardPaths: wrong ownership on

English Applications
#1

Hello,
I don’t get it: how can baloo eat 100% of my CPU, a classic problem, if it is not even enabled (and cannot be) ? And what’s with the “QStandardPaths: wrong ownership on runtime directory /run/user/0, -2 instead of 0” error?

Please check the /run/user/ directory; I’ve checked a freshly booted Leap 42.1 system and found the following:


drwxr-xr-x  5 root root   100 22. Apr 10:31 ./
drwxr-xr-x 34 root root  1080 22. Apr 10:32 ../
drwx------  3 root root    60 22. Apr 10:29 0/
drwx------  6 ...  users  180 22. Apr 10:31 1000/
drwx------  3 sddm sddm    60 22. Apr 10:28 389/

[HR][/HR]Please note that, a 13.2 system is different:


drwxr-xr-x  3 root root    60 22. Apr 10:30 ./
drwxr-xr-x 33 root root  1040 22. Apr 08:26 ../
drwx------  8 ...  users  160 22. Apr 08:45 1000/

[HR][/HR]As an aside: I suspect that, it’s not a good idea to run baloo from the ‘root’ user. On the other hand there may be good reasons to do so; who knows …

#3

@fakemoth: A question: which desktop environment are you running?
[HR][/HR]From the ‘top’ output you seem to be running some KDE Plasma components.
[HR][/HR]Also, please check the /tmp/ and /var/tmp/ directories; with KDE Plasma 5 there should be neither ‘kde-root’ nor ‘kdecache-root’ directories present.

#4

Yes, I am using plasma 5, on Leap, everything updated. I have both directories the first in /tmp the second in /var/temp. I didn’t create them, nor do I intend to run baloo as root (I was having the impression it scans only /home? and in top you can clearly see that it runs as my user?) - can I safely delete those? Why did I get them, why aren’t necessary etc, can anyone provide some more info?

In /run/user I have only a 1000 directory. Thanks!

#5

AFAIK Leap 42.1 systems running KDE Plasma 5 Desktops do not need the ‘/tmp/kde-root/’ and ‘/var/tmp/kdecache-root/’ directories; they can be safely removed.

Hmmm … AFAIK with Leap 42.1 /run/user/ should contain directories for the ‘root’ and ‘sddm’ (system) users.
[HR][/HR]

  • Check that any baloo instances running for the user ‘root’ are stopped and disabled.
  • The directory /root/.local/share/baloo/
    should be empty. - The file /root/.config/baloofilerc
    should only contain a [General] section containing “exclude filters” definitions.
