Ubuntu 20.04 Remove items from application list

Question

Environment

Ubuntu 20.04

Problem

I am trying to remove these links without luck. I have tried to find them as .desktop files.

Case 1: Duplicated link.

Case 2: Unneeded link. "Additional drivers"

Answer 1

Its a bit difficult task to know the .desktop files of the applications that are shown in overview..

But once you know the application file names.. Its easy to hide them.. for example, I have struggled to get the Additional Drivers... file. Once I came to know that this is the file /usr/share/applications/software-properties-drivers.desktop have edited like below.. added this line NoDisplay=true

[Desktop Entry]
Keywords=Drivers;
Exec=/usr/bin/software-properties-gtk --open-tab=4
Icon=jockey
Terminal=false
Type=Application
NotShowIn=KDE;
Categories=X-XFCE;GTK;Settings;HardwareSettings
X-AppStream-Ignore=true
Name=Additional Drivers
Comment=Configure third-party and proprietary drivers
X-AppStream-Ignore=true
X-Ubuntu-Gettext-Domain=software-properties

NoDisplay=true

so in the similar way you can achieve for "Kolourpaint" also. a basic way to search is ls /usr/share/applications/ | grep Kolour or change the word Kolour with paint etc..

for snap install you may need to check in this directory

/var/lib/snapd/desktop/applications
