Linux Mint 17.3: Rosa

Linux Mint e una distribuzione Linux basata su Ubuntu che ha come obbiettivo di fornire una esperienza subito pronta all’uso dato che include plugin per browser, codec audio/video, supporto ai DVD e Java di default. Fornisce dei programmi custom per la gestione e installazione della distribuzione.

Versione 17.3: Rosa

Questa versione contiene (in Inglese):

MATE 1.12

In preparation for Linux Mint 17.3, a lot of work went into MATE 1.12. Most of the papercut issues identified in Linux Mint 17.2 were fixed and some of the new features implemented in Cinnamon were ported to MATE.

The team focused on many little yet important issues which are key for a comfortable user experience.

MATE is now using the same “presence” interface as GNOME and Cinnamon. This means it now supports a very wide range of applications. You no longer need to move your mouse or to use the inhibition applet when watching a movie. MATE is now fully compatible with Totem, VLC and many other players. The screensaver won’t start while they’re playing a video.

Touchpad support was significantly improved:

• If your touchpad supports it, you can now tap or click with 2 or even 3 fingers to perform right and middle clicks.
• You can now also activate “natural scrolling” to reverse the direction of scrolling and make it feel more natural.
• And a new global option also lets you disable the touchpad (which is convenient if you never use it).

Multi-monitor support has been improved. Display settings now show output names and you’re now able to define which of your monitors should be considered “primary”.

Many multi-monitor related issues were also fixed, in particular to make sure applications and windows were launched on the active monitor (i.e. where you mouse pointer is located).

The power applet now displays model and vendor information so you can distinguish between multiple battery powered devices.

The MATE system monitor now detects Linux Mint more accurately and it’s one of the first MATE components which was ported to GTK3 in Linux Mint 17.3.

Cinnamon 2.8

Linux Mint 17.3 features Cinnamon 2.8.

Better applets

Sound applet

The sound applet was given a fresh new layout. The track information and media controls are now part of a new overlay which sits on top of the cover art.

For multimedia players which support seeking (Banshee for instance), a flat progress bar is also displayed underneath. This bar shows how far you are in the song, and you can of course interact with it to go to a different position.

Input controls, applications and output devices were moved to the right-click context menu.

Output devices now show both their name and their origin, making it easier to distinguish between them when multiple audio devices are connected.

Power applet

The power applet received many bug fixes and the way it detects and handles multiple batteries was significantly improved.

Connected devices and batteries are now displayed using the data provided by their manufacturer. In the screenshot above for instance, what was generically described as a “Wireless Mouse” in Cinnamon 2.6 is now described more accurately as a “Logitech M325”.

Workspace switcher

The workspace switcher applet is now able to show a visual representation of your workspaces, with little rectangles corresponding to each window inside of them.

System tray

In addition to traditional status icons, the Cinnamon system tray now also supports indicators.

If you don’t like indicators, you can turn this off in “System Settings” -> “General” -> “Enable support for indicators”. This results in forcing all applications which use indicators to fallback to using status icons.

Here are a few tips to recognize status icons and indicators:

• Status icons are rendered by their application, often using GTK menus and widgets.
• Indicators are rendered by Cinnamon, with a Clutter menu which looks similar to the panel itself.
• Status icons can have tooltips and a context menu, indicators cannot.
• In the Logs section of “Looking glass” (Alt+F2+lg), you can see what status icons (“systray”) and what indicators (“indicator”) are loaded by Cinnamon.

The screenshot above shows the Steam indicator. Notice how its menu is using Clutter widgets and following the Cinnamon theme. If you disable the support for indicators, Steam will use a traditional status icon instead.

Support for status icons in the system tray also received a lot of bug fixes, in particular for applications such as Pidgin, Shutter, Filezilla and Thunderbird.

Window list

The window list is now able to show window thumbnails.

This is configurable and it can be disabled in the applet preferences if you would rather just see tooltips.

Visual improvements

The traditional animation effect for minimizing windows was fixed and it is now working with multiple panels.

Some polish and slight visual improvements were applied to both the classic and preview Alt-Tab application switchers.

Box pointers (the little arrows joining applet menus to the panel) received some attention and now look much better than before when close to the edge of the screen.

The Alt-F2 run dialog received bug fixes and better auto-completion.

Better settings

Display settings

The display settings now show both the name of your monitors and the name of the output plug they’re connected to. These are known as “output names”.

In the screenshot above we see for instance two identical Dell monitors, one connected via the DP-1 Display Port, and one connected on HDMI-0, the first HDMI port.

These are the same output names you can see when using xrandr and in the “Login Window” preferences to tell MDM which monitor to use to show the login screen.

Other improvements

In “Account Details” and “Users and Groups”, a strength indicator was added to the dialog window which lets you change passwords.

Applets now reload themselves automatically when updated.

Better window management

Support for multiple monitors was significantly improved. The mapping of new windows, dialogs, OSD info (such as the workspace names) was reviewed to make sure everything appeared in the right place and on the appropriate monitor.

Improvements related to frame synchronization which were implemented in Mutter (the GNOME Shell window manager) in cooperation with NVIDIA were ported to Muffin (the Cinnamon window manager). These changes should fix rendering issues with NVIDIA cards but could also have a positive impacts on ATI and Intel chipsets.

Dialog windows are now attached to their parent window by default. This setting was already present in Cinnamon (in “System Settings”->”Windows”->”Behavior”->”Attach dialog windows to the parent window”), but it was improved in version 2.8; Dialog windows are now attached to the center of their parent window rather than their titlebar, and the shading of the parent window was made a little more obvious than it was before.

Better backend

Settings daemon

Cinnamon now supports microphone mute buttons.

HiDPI detection was improved, in particular for TV screens over HDMI.

XRANDR support was significantly improved, many bug fixes were ported from Gnome Shell.

The Cinnamon Settings Daemon is more robust than before and shouldn’t crash anymore when one or some of its modules fail to load.

Session manager

The Cinnamon logout sequence was reviewed and some changes were introduced to make it faster and to make it look smoother. The timeout for the session “EXIT” phase was reduced to 1 second, and the settings daemon and the window manager, which are respectively responsible for painting applications with the right GTK theme and for rendering window titlebars are now the last programs to die.

Cinnamon 2.8 also features:

• Better support for QT5 applications, which now look more native and use the GTK theme.
• Better XSMP support.
• Better logs (You can enable logs to ~/.xsession-errors via the “org.cinnamon.SessionManager debug” gsettings key. Logs now also include time delta information to help identify cases where an application makes the login or logout sequence lag).
• A fully configurable auto-start blacklist (The key is in “org.cinnamon.SessionManager autostart-blacklist”. This was only partly configurable in previous versions.).

Performance improvements

The calendar applet used to wake up the CPU every second even if seconds weren’t shown. This was fixed and further reduces idle CPU usage.

The absence of disk cache was identified as the reason why the first Cinnamon session after a shutdown/reboot was significantly slower to load than any subsequent session. To tackle this issue, Cinnamon 2.6 introduced “preloading”, which goal was to initialize parts of Cinnamon in the background, while you were busy typing your password at the login screen. Thanks to your feedback and testing done on a wider variety of hardware, “preloading” was reviewed in Cinnamon 2.8. Although it helped in reducing the most costly steps involved in the initialization of a Cinnamon session, the gains were unfortunately marginal. Preloading also proved to slow down the startup sequence, and in particular the loading of the login screen. It was therefore removed from Cinnamon 2.8.

Nemo improvements

“Quick-Rename” landed in Nemo. This feature, which is probably most appreciated by Windows users, consists in renaming files and directories by clicking them, waiting a bit and clicking them again. Quick-Rename is disabled by default. To enable it in Nemo, click on “Edit”->”Preferences”->”Behavior”->”Click twice with a pause in between to rename items”.

Nemo now automatically detects issues related to thumbnails and allows you to quickly fix them (you’re prompted with a password dialog when this requires administration privileges).
