2) Budgie

Solus 4 ships with the latest release of Budgie, which is accompanied by a great new GTK theme (Noir) named Plata.



Application Menu

The application menu had received small refinements that fix some of the older issues of repetition (when a search made), and the ‘Sundry’ category got deleted and appended to the ‘Others’ category.

Caffeine Mode

The new version of Budgie comes with a ‘Caffeine Mode,’ which does not allow the system to suspend or lock when you’ve had it enabled. Some features of this new applet are:

Icon Tasklist

New Budgie gives the Icon Tasklist a significant update with improved detection and grouping of the programs and a new pop-over menu.

The new menu enables users to:

  • Close all windows of a program
  • Control windows easily with tasks like maximizing, minimizing, etc. and quickly move them to different workspaces
  • Quickly favorite/unfavorite programs
  • Quickly launch a new instance of a program
  • Minimize or focus on an application by scrolling down or up (respectively) on the program’s Tasklist button
  • Toggle minimize or un-minimize between various programs

Additionally, and importantly, it enables users to execute tasks specific to an application right from the Tasklist. For example, the TaskList button of Firefox gives an option to open a new private window without even opening it.

The widget and notification center of Budgie receives many performance improvements.


Week numbers on the Calendar come in handy.

The notifications will group according to the program’s category. Notifications can now be cleared all at a time, all of one program at a time, or one program at a time.

Notification summaries and descriptions are now efficiently displayed in the pop-up notifications. No notifications for power such as suspend and printers get presented.



The sound widget has received significant improvements.

  • The sound widget now is split into input and output
  • The option for 150% volume is now possible
  • Controlling the volume from the application is possible and not only for graphical, but also for CLI based music players
  • Easy switching between different input and output devices

The new release of Budgie features new settings and configuration options for the Budgie Desktop Settings application. Let us go through some of them:


The new configuration for this category enables automatic blacklisting of the themes and icons packs that don’t bode well with Budgie. It may seem a bit irrelevant, but this can save your system from a terrible crash, and you from a terrible experience.

A new option to control the location of notification pop-ups is a new feature. The developers have expressed that instead of working more on their “internal” themes, they are trying to provide better support for third-party GTK themes.

This new major release sure brings a lot of improvements and much-needed new features to Solus. Budgie being a comparatively new DE, it is growing, and growing well.

  1. Now the Kernel has been upgraded to 5.0.5-113.current Can you help me with playing HD videos in Prime Video. Few users of Solus say they are able to play HD videos, but i am not. Did you try the Solus 4 and were you able to play?

  2. I left Solus as i was not able to play HD videos in Prime plus had screen tearing. (bad configuration from my side). Switched to Windows and when Linux gets HD support i will jump back

  3. Hi Jason,
    I can’t understand what you mean by “HD videos”. It appears that the same quality is available both in windows 10 and Solus, both in Chrome: “maximum quality” of stream is available in both, and visually they appear the same.
