# KDE 6's Dolphin on MATE

## Preamble

Since Caja has it's issues, I tend to prefer Dolphin. And KDE 5's Dolphin used to work **very well** on MATE. Then I gave the order: told comrade `apt` to upgrade my ancient Debian Bookworm to Debian Trixie. Of course, Dolphin is now broken — or rather it's compatibility towards MATE. 

I should imagine KDE devs. won't exactly jump at the chance of making it work with it's «competing» DE, so I'm still trying to fix it with little success. This article is certainly a testament to my failure. 

## Fuckerie Number I: Dolphin no longer uses the icon theme selected on MATE

Yeah, I don't know how to fix that one, I guess I'll just have to accept the Windows 7 icons I used to use on Plasma. 

## Fuckerie Number II: File associations are broken

You click any file, it opens a file dialog asking what program to use, and lists no program. You have to type the command manually. It seems to be related to broken XDG stuff, [according to Reddit](https://www.reddit.com/r/kde/comments/1bd313p/dolphin_not_recognizing_file_associations/), letting `kbuilsycoca6` daemon run seems to have solved the problem. 

## Fuckerie Number III: Telegram icon vanishes from the systray

While this isn't technically Dolphin's fault, I'm gonna put it into it's tab because Dolphin can't do shit without launching `kded6`. Then, `kded6` proceeds to register KNotification interface on DBus, which Telegram seems eager to bind to and will immediately send the systray icon there. And, since I'm using MATE (GTK-stuff), that crap just vanishes from the systray. 

Killing `kded6` makes the icon reappear, but once you do as little as opening a file on Dolphin, it will relaunch `kded6`.
