optdepends in the Dolphin PKGBUILD should be expanded on, report this on the bugtracker. -- Alad (talk) 20:42, 31 December 2014 (UTC)

Out of the box, Dolphin renders no icons. There's a Troubleshooting entry, but perhaps this should be moved up to installation? I can't imagine many people actually want dolphin with no icons. Or is this perhaps a missing dependency and qt5ct needs to be added as a dependency? WhyNotHugo (talk) 20:34, 5 August 2022 (UTC)

The Qt 5 configuration tool isn't what makes it work, it's using it to set an icon theme. That tool shouldn't be a necessary; it sounds like there is a deeper cause of this invalid initial state. If nobody else finds out, I will probably look into it while I work on Qt because this issue should be affecting other applications. -- CodingKoopa (talk) 19:38, 7 August 2022 (UTC)

It seems that when no icon is explicitly defined, Dolphin renders with no icons, rather than just use _any_ icon theme. I mentioned this in #kde and it was suggested that I report this kind of issue upstream, so I have at https://bugs.kde.org/show_bug.cgi?id=457581 My familiarity with Qt/KDE is limited, so any additional knowledge is welcome.

Great! They appreciate it when people file bug reports. I didn't know this pertains to non-KDE setups, that makes more sense. -- CodingKoopa (talk) 20:14, 10 August 2022 (UTC)

Dolphin emits transfer progress / complete notifications properly when running under Plasma with the Plasma dock and the "Application Progress" notification turned on.

In any other environment, it just renders a kdialog box with no notifications, even with a custom notification server like Dunst running and connected to session D-Bus.

Is this some configuration error or is the above intended behaviour? If it is intended, are there any workarounds for wm users?

I tried using progress to capture system-wide coreutils' status and then emit notifications myself, but Dolphin-initiated moves and copies don't even show up! Beningodfrey4 (talk) 19:52, 22 February 2024 (UTC)

The last troubleshooting section instructs people to run kbuildsycoca6 with the environment "XDG_MENU_PREFIX=arch-" every time. Wouldn't it make sense to instead instruct to add the environment variable to the user's relevant session config so that it wouldn't interfere when running the actual Plasma session (will rebuild on startup) and also let KDE apps run the tool by themselves without emptying the database? Keep Yourself Safe (talk) 11:29, 1 December 2025 (UTC)

I sadly dont know what parts of the desktop rely on XDG_MENU_PREFIX and what could break by setting XDG_MENU_PREFIX=arch- generally. Thats why I did not recommend doing this. If you know more about it pls tell.

(I am not sure if I understood you correctly)

This environment variable sets the prefix for menu entries (like `enlightenment-`). If there's none, it guesses by the current session name. That doesn't exist in all DEs and exists in pretty much no window manager. Setting it to "arch-" makes it read the arch- entries in particular, not "hyprland-" (doesn't exist).

Also, this is not exclusive to Dolphin (kmail also suffers from this for example), and other apps might potentially be unhappy by invalid XDG menu entries. Maybe just move it out of this article altogether and keep a little "see #thing" here? Keep Yourself Safe (talk) 12:56, 20 December 2025 (UTC)

In that case, setting it more permanently (eg. in the hyprland-conf) might a good idea. But do you see any actual behavior changes between setting it/not setting it? I (with a bit of messing around) did not see any. Dolphin does not seem to trigger the cache updates automatically even if XDG_MENU_PREFIX=arch- is set.

I am also not sure if changing this might interfere with some few compositors that use it.

I would not know which page to better put this info on. I think this might be KDE specific, but as the KDE page is kinda a page for KDE Plasma, I dont think it fits there. (and I find it pretty ok on the dolphin page)

install hooks that change menu stuff now also clear the cache it seems

Oh, it will. But it's not destructive, it's just gonna reorder the menus and stuff. I don't see how it's any worse than swapping in a different window manager to a DE on X11, or putting mpvpaper on top off whatever wallpaper provider you already have: it's just another option.

> the KDE page is kinda a page for KDE Plasma

Well, I agree but it does include stuff useful on other environments, like KDE Connect. I guess the Xdg menu page is also a good candidate. Keep Yourself Safe (talk) 20:02, 24 December 2025 (UTC)
