View audio CDs
Support for audio CDs is provided by the kio extension.
Dolphin and other KDE applications use
kcmshell5 componentchooser and select Terminal Emulator > Use a different terminal program.
Some users will not have the module installed. Instead, the default terminal can be changed by modifying the kdeglobals configuration
~/.config/kdeglobals, and adding
TerminalApplication=terminalname under the
[General] tab. Note, it is likely that this method will not make the internal Dolphin terminal window (opened with
F4) use the terminal specified in the kdeglobals configuration.
Dolphin uses KIO slaves for network access, trash and other functionality, unlike GTK file managers which use GVFS. Available protocols are shown in the location bar (editable mode) . To quickly bookmark them, right-click in the workspace, and select "Add to Places".
You can install KIO slaves manually. For example, to browse your Google Drive in Dolphin, install.
Device names shown as "X GiB Harddrive"
Create a filesystem label, or a partition label, and Dolphin will show this label in the device list instead of the size. See Persistent block device naming#by-label.
Moving files into trash takes long on external drives
For moving files into the Trash, it's required that the user has exclusive access rights to the Trash. The rationale being that you don't want that others can see what you deleted. For that, a folder such as .Trash-1000 is created on the external drive, with permission mode
If the correct access permissions can't be set, dolphin will (unlike GNOME) move the files to the trash in the home directory, which takes time.
To mount USB-Sticks / external HDDs, Dolphin uses Udisks. FAT32 / EXFAT / NTFS don't support UNIX file permission, udisk mounts them by default with mode 755.
To configure udisks to mount these drives with mode 700, have a look at the file
/etc/udisks2/mount_options.conf.example. Copy the file (the name should end with .conf), uncomment the relevant part and add for the three filesystems to the lines with xyz_defaults the options
Fonts in selection frames may become transparent when using the GTK Qt style. Native Qt styles such as Cleanlooks and Oxygen are unaffected.
Icons not showing
If icons are not displaying on Dolphin, and an error similar to "Pixmap is a null Pixmap" appears on the console, try putting this line in your
[ "$XDG_CURRENT_DESKTOP" = "KDE" ] || [ "$XDG_CURRENT_DESKTOP" = "GNOME" ] || export QT_QPA_PLATFORMTHEME="qt5ct"
If icons are still not able display, and same error "Pixmap is a null Pixmap", run
qt5ct, looking at "icon theme" tab. Choose one icon theme and apply.
Icons are too big
If icons are too big on Dolphin in not KDE environment, start it with:
XDG_CURRENT_DESKTOP=KDE KDE_SESSION_VERSION=5 QT_AUTO_SCREEN_SCALE_FACTOR=0 dolphin
Mismatched folder view background colors
When running Dolphin under something other than Plasma, it is possible the background color in the folder view pane will not match the system Qt theme. This is because Dolphin reads the folder view's background color from the
[Colors:View] section in
~/.config/kdeglobals. Change the following line to the R,G,B values you prefer:
... [Colors:View] BackgroundNormal=23,24,24 ...
