Hi everyone!

I'm trying to troubleshoot why Dolphin takes such a long time (about 6 seconds) to start on my brand new laptop. The issue is not related to hardware performance (starts Gimp in less than 4 seconds). Tons off googling has not helped me out.

I've tried the following:
- Clearing the cache.
- Ensured that no network drives are mounted at start.
- Stopping dropbox service.
- Reinstalling dolphin.
- Removed /.config/dolphinrc
- Ensured that I do not have much data in my home directory.
- Checked that speed does not increase when i start dolphin in a different directory.

Command line output:

Code: Select all

org.kde.dolphin: Ignore KIO url: QUrl("timeline:/yesterday")

kf5.kio.core: KSambaShare: Could not find smb.conf!
inotify_add_watch("/home/mattias/.dropbox/aggregation.dbx") failed: "No such file or directory"

It pauses after the first line and right before "kf5.kio.core: KSambaShare: Could not find smb.conf!".

I'm running Kubuntu 18.04 with Plasma 5.12.07 and Dolphin 17.12.3.

Any suggestions on what I could try next?

It obviously expects a working Samba installation, which can't be found. Check your samba installation first.

Thank you! I installed samba, the smb.conf error is gone but it still takes 6 seconds to start dolphin. The rest of the output looks the same.

Any other ideas?

Shameless bump.

Any logfiles, tools i can use to troubleshoot this?

Sorry, totally overlooked this. Since you installed samba, I guess something has change in the output you get when you start it from the command line, care to show it?

Sorry, missed your reply. It's the same as above without the samba line:

The 'ignore' lines seems ok and disabling the dropbox service does not help.

Is this a standard installation of Kubuntu or did you remove or add some components? FWIW an upgrade might be a good idea...

I have one suspect. It is kio-gdrive (google drive integration for dolphin).
But I have uninstalled it, it is not visible in the Services list or in Networks.

I'm running Kubuntu 18.04 and all packages are up to date.
I have also run apt autoremove and it is clean.

There seems not to be any verbose option.
Any log file or setting i could check?

You could check the lines under

Code: Select all

[Open-with settings]

in the file .config/dolphinrc which is in your home directory (the .config/ path is hidden, you can activate this view in Dolphin with the combination Alt+.)

AFAIK Kubuntu 18.04 ships a much older Plasma, and therefore also Dolphin. My current one here is 19.04.3

I removed .config/dolphinrc multiple times and it is currently:

Still slow to start.

I upgraded to 19.04 and that resolved the issue.

Thank you for your replies!
