I have created some .desktop files for some AppImages and they have all ran great up until I installed the Hyper Terminal. Now I get the following error:

Plasma

KDEInit could not launch 'Hyper':
Could not open library 'libkdeinit5_Hyper'.
Cannot load library libkdeinit5_Hyper: (libkdeinit5_Hyper: cannot open shared object file: No such file or directory)

I would like to fix this so that I can keep Hyper. I am using Kubuntu 18.04 with the latest updates. Will someone please help? Here is an example of the one I have for Minecraft:

[Desktop Entry]
Type=Application
Name=Minecraft
Comment=Minecraft
Icon=/home/AlphaGenius/Pictures/minecraft.png
Exec=/home/AlphaGenius/Minecraft/minecraft-launcher.sh
Terminal=true
Categories=Minecraft;Games
Name[en_US]=Minecraft.desktop

Here is another that I have for Cura:

[Desktop Entry]
Type=Application
Name=Cura
Comment=Cura
Icon=/home/AlphaGenius/Pictures/cura.png
Exec=/home/AlphaGenius/cura.AppImage
Terminal=true
Categories=Cura;Design
Name[en_US]=Cura.desktop

There may be better ways but I am just learning.

  • You mean you mention the terminal in the Exec line of the desktop file? Is that necessary? Please post an example. – cipricus Jan 12 at 19:07

    I have updated my question with a couple of examples. – Jason Amerson Jan 12 at 19:39
  • So, you do not use Hyper in the Exec lines, yet Hyper is started when you run the desktop files. That is odd. What happens when you execute other desktop files, like those in usr/share/applications? – cipricus Jan 12 at 19:43
  • btw: the Minecraft desktop file doesn't execute an AppImage file, does it? – cipricus Jan 12 at 19:51
  • I figure out what I was doing wrong. I have added an answer to my own question. Thanks for your help! – Jason Amerson Jan 12 at 19:56

The problem was the line Terminal=true.


I got it to work now. I added %U to the end of the exec line and then changed the terminal to false. Now it works like it should. Thank you @cipricus for helping me and leading me in the right direction. The modified script is as follows:

[Desktop Entry]
Type=Application
Name=Cura
Comment=Cura
Icon=/home/AlphaGenius/Pictures/cura.png
Exec="/home/AlphaGenius/cura.AppImage" %U
Terminal=false
Categories=Cura;Design
Name[en_US]=Cura.desktop
  • What does the %U mean? And did you fix the Minecraft launcher the same way? – wjandrea Jan 12 at 20:00

    I haven't noticed the Terminal=true line. That is the cause, you can simply remove the Terminal line altogether, and I think %U is not needed if all you want is execute the program. It would be needed (%f, %F, %u or %U) if you want to open files with it by selecting them. But then you need the Mimetype line. – cipricus Jan 12 at 20:04
  • @wjandrea - askubuntu.com/q/30210/47206, but I guess such arguments are not necessarily needed, unless you use the application in order to launch multiple selected files. – cipricus Jan 12 at 20:05
  • @cipricus - I think you are right about the Terminal line. – Jason Amerson Jan 12 at 20:09
  • note that in case you want to start/open/run/play files in an AppImage program (and associate file types to that program) you will need a Mimetype= line in your .desktop file. – cipricus Jan 13 at 13:03
