I use Budgie DM on Ubuntu 19.10 (firstly noticed on 19.04).

I've installed kmplayer using 

sudo apt install kmplayer

When I run kmplayer from terminal: $ kmplayer, it runs successfully throwing only:

 Invalid Context= "Mimetypes" line for icon theme:  "/usr/share/icons/Faba/symbolic/mimetypes/"
 Icon theme "elementary" not found.

I can drag and drop videos into it and it plays them.

But when I try to open kmplayer using desktop menu, its icon appears on dock panel and disappears after 15 seconds without main window opening.

Also, when I try to open a video using Context menu -> Open with -> Kmplayer it behaves the same wrong way.

Gnome MPV, VLC, Parole Media Player open videos without issues.

KMPlayer version: 0.12.0b (c) 2002-2016, Koos Vriezen

Why could it be opened by terminal command and could not be opened by Menu item clicking or by opening video using Open with context menu clicking?

  • as for the KDE icon theme it is something related to this https://askubuntu.com/questions/1007563/kde-application-icon-not-displayed-in-ubuntu – JoKeR Dec 09 '19 at 20:55
  • If you simply need a video player just go with SMPlayer it saves you lots of pain. – JoKeR Dec 09 '19 at 21:01
  • Ok. Thank you for explanation! But I'm curious about it. Why it could be launched with correct icon displayed when started from terminal and could not be launched through GUI? – Gryu Dec 09 '19 at 21:19
  • that is because you are launching KDE application on Gnome desktop environment, you might be missing KDE icon themes or plugins required by kmplayer. – JoKeR Dec 09 '19 at 21:38
  • I'm sorry for asking, but why does it work correctly when I run it using terminal command: `kmplayer`? – Gryu Dec 09 '19 at 23:35

It can't start by clicking the menu item because KDE launches it with additional options.

To fix that:

  1. Open KDE Menu Editor.
  2. Find the KMPlayer item.
  3. Change the Command entry with kmplayer without any options.

That works for me.
