# KDE 6's Dolphin on MATE

## Preamble

Judge me, I prefer Dolphin to the absolutely joke that Caja is. Now, you may want to curse me because «WeLl, IT's aN OpEN soUrCe ProJeCT, ConTRiBuTe YOuRsElf»-kind of argument and be absolutely right. But I lack the time and energy, so I just use Dolphin instead and complain online about Caja. 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. In order to un-fuck it, I had to research a bit. And since I'm 100% going to forget what I did, we have this present article to remind me on how I fixed it — _NO! Documenting? I know, right?_ 

## 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.
