    [xubuntu] Thunar File Manager running EXTREMELY slowly and crashing

    Hello everyone.

    Can anyone give me some troubleshooting advice?

    I've used Xubuntu for years and love it. A few weeks ago, my filemanager Thunar (1.8.14) is lagging and crashing.

    For example, it can take 30 seconds to open a folder, and sometime when I try to close the folder, I get the message:

    Warning

    This window might be busy and is not responding. Do you want to terminate the application?

    <folder name> - File Manager
    I had the idea of trying to re-install Thunar. So I went into SOFTWARE, and found Thunar and INSTALLED, But when I click remove and then "ok", nothing further happens.

    Any advice?

    ps -

    I tried sudo apt remove thunar followed by sudo apt install thunar, but the problems persist.

    Can you check if this also happens in other file managers, e.g. PCManFM or Dolphin?
    Xubuntu 22.04, ArchLinux ♦ System76 hardware, virt-manager/KVM, VirtualBox

    Thunar has no separate configuration files, it's settings and options are stored in xfconf and you can access them graphically with xfce4-settings-editor. You might want to take a look whether there's something wrong in there.

    The last time Thunar was misbehaving on my system the actual culprit was not Thunar at all, it was the thumbnailing service tumbler which was called by Thunar and tried to make thumbnail images for some rather big video files ... A few changes to /etc/xdg/tumbler/tumbler.rc ended that problem.
