Got an application, but you want to make it in-visible from start menu, app grid, app launcher search result, and dock launcher?
It’s easy to do the trick by adding rule NoDisplay=true or Hidden=true into the ‘.desktop’ file for that application. And, here’s how to do it step by step.
Hide Shortcut Icon for native Deb/RPM & Snap apps
For applications installed as the native .deb (or .rpm for RPM based systems), and Snap packages, the ‘.desktop’ files are usually stored in /usr/share/applications directory.
1. First, open terminal either from start menu or by pressing Ctrl+Alt+T on keyboard in Ubuntu. When it opens, run command to navigate to that folder:
2. Then, find out the .desktop file by either listing all of them via ls command. Or, filter via:
ls | grep 'keyword_here'
3. Once you find out the .desktop file for your applications, edit it via command:
sudo gedit your_application.desktop
Replace gedit with your system text editor, or use nano command line editor that works in most Linux.
4. Finally, add (or change value if the key already exist) the line below:
Finally, save the file. For nano text editor, press Ctrl+X, type y and hit Enter.
In next time you logging into the system, the app shortcut will no longer exist in start menu, app grid, the left/bottom dock, and ‘Activities’ overview search result.
Hide Shortcut Icon for Flatpak Apps
For the universal Flatpak applications, the ‘.desktop’ files are located in ‘/var/lib/flatpak/exports/share/applications/‘ directory.
1. So, first open terminal and run command to navigate to that folder:
2. Use ls or ls |grep 'keyword' to find out the file.
3. Finally, edit it either via Gedit or other text editor:
sudo gedit your_application.desktop
Add the NoDisplay=true line and save the file. Also, log out and back in to see result.
Copy & paste the .desktop file into local folder
The previous change may be overridden after updating the software package. As a workaround, you may copy & paste the .desktop file into local folder and then do the change. Your system will always take use of the local one.
For native package and Snap, open terminal and run command to copy the file:
Got some ePub and/or MOBI books in your PC? Debian / Ubuntu has recently includes a package in their repository for generating thumbnails for these files.
As you may know, Linux Mint 21 was released recently with a thumbnail generators for AppImage, ePub, MP3 and RAW files. Debian/Ubuntu now has similar tool called gnome-epub-thumbnailer, though it’s only for ePub and MOBI books.
With the package installed, the default file manager will no longer display the universal “e” image with green background for all ePub files. Instead, it shows thumbnail book covers.
Don’t know if Ubuntu 22.10 will come with it out-of-the-box, since it’s not released yet. But, user may manually install the package by running the apt command below in terminal.
Open terminal (Ctrl+Alt+T) and run command to install gnome-epub-thumbnailer in Ubuntu 22.10 or Debian Unstable:
For users of Krita digital painting software, there’s a bad news that the Krita Lime PPA is abandoned. The repository page is even removed!
Krita Lime PPA was the ‘official’ (definitely not, but maintained by volunteer) package source in Krita’s website until the app switching to AppImage. It maintained the most recent packages for Ubuntu users who are sticking to the native .deb package.
The PPA recently announced the deprecation note: “The Krita Lime PPA has been deprecated. Please use official AppImage packages from the official Krita site instead“, and completely removed the PPA page.
How to Remove Krita Lime PPA:
If you still have the PPA in your system, you may remove it either by using “Software & Updates” utility under “Other Software” tab.
