MATE-Desktop or Cinnamon-Desktop

MATE is one of the most popular Linux desktop environments, alongside the Cinnamon desktop environment. The MATE desktop is based on the Gnome Shell. Linux Mint is one of the many distributions that include the MATE desktop and Cinnamon desktop.

MATE Desktop Environment

The history of MATE is quite exciting. It’s actually the sequel to GNOME 2. GNOME is the most widely used desktop environment. But the big change came with the release of v3. It was a completely different design than that of the classic GNOME 2. It caused a huge uproar in the community, which loved and nurtured the classic look.

This is where MATE began its journey as a fork of GNOME 2 with numerous improvements and new features. Still, it remains true to the original GNOME 2.

Linux Mint is one of the most popular Linux distributions, many choose the Linux Mint Cinnamon Edition to install as operating system. Linux Mint is also involved in the development of MATE, a classic desktop environment that is the sequel to GNOME 2, the default desktop of Linux Mint between 2006 and 2011. Although some features are missing and its development is slower than Cinnamon’s, MATE runs faster, consumes fewer resources and is more stable than Cinnamon.

Install MATE-Desktop

If you want to switch to the MATE desktop environment at a later time after installing Linux Mint Cinnamon Edition, there is the possibility to add a second graphical desktop environment as an alternative to the already installed desktop environment, with the following command from Gnome Terminal Shell.

$ sudo apt install mint-meta-mate

Install Cinnamon-Desktop

If it is the other way around, if you have the Linux Mint MATE Edition installed on the system, the Cinnamon desktop environment can be added.

$ sudo apt install mint-meta-cinnamon

Now you have to log out, the login screen now shows an icon next to the user name, via the icon “Select Desktop environment” the graphical desktop environment is selected.

Figure: Select Linux Mint desktop environment.

Kopano WebApp circle rotates endlessly in Firefox

In this Tutorial we show you how to solve the issue with the Kopano WebApp Login using the Mozilla Firefox Browser under Windows.

Symptom

If you try to Login via the Kopano WebApp 3.5.2 from Mozilla Firefox 95 under Windows, an animation with rotating circle appears after entering user and password, the circle continues to rotate non-stop, the page stops and it doesn’t go any further, after pressing the F5key or Ctrl+R (Refresh) authentication resume successfully.

Cause

The browser performs a Javascript function that sends a fingerprint (special ID) to the server (at the login request) and later when logging in, the server checks the fingerprint for compliance. Mozilla Firefox (version 94.0.2 / 95.02 64bit) distinguishes the second fingerprint from the first. With Firefox on Linux, the behavior was not detected and does not seem to be known.

Solution

The workaround/solution is to remove the Arial Narrow font from Javascript, so that the fingerprint does not change. To do this, edit the Java file fingerprint.js.

$ nano /usr/share/kopano-webapp/client/fingerprint.js

Delete the text Arial Narrow; (marked in red) (Arial Black; Bodoni MT).

After removing “Arial Narrow” from Javascript, the session fingerprint is no longer changed, the login passed successful.

Try now Kopano WebApp Login

This app contains the Kopano WebApp, which users can use to conveniently carry out their everyday communication and organizational tasks, from e-mail and calendar entries to file management and video calls. The WebApp can be expanded with plugins and used with various themes that can also be customized.

To install Kopano WebApp, the Kopano Core App must already be installed on at least one server. The Kopano WebApp does not necessarily have to be installed on the same machine. It can also be installed on several servers at the same time for load balancing or for optimized data communication. This app is also required if the Kopano DeskApp is to be used.
