一些文件管理器在 kubuntu、bullseye 11 上打开速度非常慢。我在 UDisks2VolumeMonitor 上遇到了问题，因此解决了这个问题，运行所需的时间减少了一半。 （ps. UDisks2VolumeMonitor --> mraid2 上的问题未修复）
通过应用其中一些来修复：
sudo apt-get install appmenu-gtk2-module
chmod +x /usr/libexec/gvfs-gphoto2-volume-monitor
sudo apt install --reinstall glib2 -y
sudo apt install --reinstall gsettings-desktop-schemas
fixing XDG_DATA_DIRS paths

Do you have overlay scrollbars activated? If yes, take a look at this bug report:
https://bugs.launchpad.net/ubuntu/+source/xfce4-settings/+bug/1239014
https://gitlab.gnome.org/GNOME/gvfs/-/issues/541
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=950174
所以我测量了这些文件管理器在我的系统上运行所需的时间：Dolphin 和 Krusader 不到 10 秒。其他超过 30 秒。
注意：我在自供电 USB 集线器上安装了 8 个 USB 硬盘。
所以我想追查原因，例如。 Nautilus 需要 1 while 分钟才能运行！我怎样才能做到这一点？
您是否推荐任何其他更快的文件管理器（不基于终端）？
