Lumina Desktop Walkthrough with Ken Moore

Brought to you by: System76

PC-BSD Is Developing Its Own Desktop Environment

The PC-BSD project is developing its own desktop environment from scratch! The ultimate plan is for Lumina to become a full-featured, open-source desktop environment that may ultimately replace KDE as its default desktop environment.

Lumina Desktop · GitHub

Lumina-DE is a lightweight, BSD licensed desktop environment designed specifically for use on FreeBSD (although it should be easily portable to other Unix-like OS’s as well).

PC-BSD 10.0.3 Preview: Lumina Desktop

Lumina/10.1 – PC-BSD Wiki

The Lumina Desktop Environment (Lumina for short) is a lightweight, XDG-compliant, BSD-licensed desktop environment that focuses specifically on streamlining the ability to get work done while minimizing system overhead. It is specifically designed for PC-BSD® and FreeBSD, but has also been ported to many other BSD and Linux operating systems. It is based on the Qt graphical toolkit and the Fluxbox window manager, and uses a small number of X utilities for various tasks, such as numlockx and xscreensaver.
Lumina’s features include:

Very little system overhead.
Intelligent “favorites” system for creating quick shortcuts to applications, files, and directories.
ZFS file restore functionality through the “Insight” file manager.
Desktop system is plugin-based, which is similar to Android or other modern operating systems.
Simple access to operating system-specific functionality such as screen brightness, audio volume, and battery status.

System Dashboard

The “System Dashboard” button is located at the far right of the panel.

This button provides quick access to hardware-specific information or operations, as supported by your operating system. The possible menu entries are:

A slider for changing the audio volume for the system from 0% to 100%. If the operating system provides a mixer utility, an icon will also appear. Click the icon to launch that mixer utility for advanced control of the audio system.
A slider for changing the screen brightness from 0% to 100%.
The current status of the battery, if your system has one, and the estimated time remaining if that battery is discharging.
A listing of the number of virtual workspaces that are in use, with buttons to switch between the different workspaces.
The log out button for ending the desktop session. When the log out button is clicked, a window of choices will be displayed in the middle of the screen. The choices include: Log Out, Restart (if the user has permission), Shutdown (if the user has permission), Cancel (to exit the choice menu), and Lock Screen.
Lumina/10.1 – PC-BSD Wiki

Right-Click Menu

If the user right-clicks on the desktop, a menu of quick shortcuts will appear for instant access and the title of the menu will indicate the name of the workspace. While this menu can be customized, here is a quick summary of the default items on the menu.

Terminal: used to launch a system terminal. The default is xterm, but this can be customized.
Browse System: launches the file manager. The default file manager, Insight, recommended, but this can be customized.
Applications: provides a drop-down menu of all the applications registered on the system, organized by category and name. Click an application to launch it. There are also a few shortcuts at the top of the application menu: one for opening the user’s home directory, one for launching the control panel, if the operating system provides one, and one for launching the graphical application installer, if the operating system provides one.
Desktop Settings: contains shortcuts to configuration utilities for the Lumina desktop environment, such as the control panel, if provided by the operating system, the screensaver configuration utility, the desktop configuration utility (lumina-config), and the Qt configuration utility (if installed).
Unlock/Lock Desktop: used to lock or unlock the desktop plugins. When unlocked, desktop plugins become “active” and can be moved, resized, or removed from the desktop. It is recommended to leave the desktop locked during normal operations.
Snap Plugins to Grid: this option only appears when the desktop is unlocked. Used to align and resize all the desktop plugins on an invisible 32×32 pixel grid, with special adjustments to align on the bottom and right screen edges if necesssary, in order to provide a uniform appearance.
Log Out: opens the system log out window, with options to shutdown/restart the system (if the user has permission), log out of the desktop session, lock the system, or cancel the log out window.

Lumina Configuration Utility

The Lumina Configuration utility allows the user to configure every aspect of the desktop and is the recommended way to make changes. To launch this utility right-click the desktop and select “Desktop Settings” → “Desktop” or type lumina-config from an xterm.

Insight File Manager

The Insight file manager allows the user to easily browse and modify files on the local system on a per-directory basis. To open Insight, right-click the desktop and select “Browse System” or type lumina-fm from an xterm.

It is possible to open up additional directories through the tab system (use “Ctrl-T” or click “File” → “New Tab”), allowing the user to easily manage multiple locations on the system. Insight also features the ability to “bookmark” locations on the system for instant access via the “star” button. Once a location has been bookmarked, it will be available via the “Bookmarks” menu at the top of the window. Any removable devices that are available on the system will show up in the “External Devices” menu, if supported by the operating system. When an item is selected, the options on the left side of the screen will show the possible actions that may be taken with regards to that item. Possible actions include: open, open with (will prompt for the application to use), add to favorites, rename, cut, copy, paste, and delete. By default, the actions buttons are visible. They can be made invisible by clicking “View” → “Show Action Buttons”.

A few additional options may be available at the bottom of the window, depending on the directory being viewed and the types of files that are in it:

New Dir: the ability to create a new directory will become available if the user has permission to modify the contents of the current directory.
Slideshow: if there are image files in the directory, there is an option to view those image files as a slideshow.
Play: will appear if there are supported multimedia files in the directory. The types of files that are supported depends on what multimedia plugins are installed on the system. If a particular file is not recognized as a multimedia file, install the associated multimedia codec using the operating system’s application management software and restart the file manager.
Backups: if the system is formatted with ZFS and snapshots of the current directory are available, this button will appear. Snapshots are organized from oldest to newest, with the most recent snapshot selected by default, and the contents of the directory at the time of that snapshot are displayed. To restore a file or multiple files, select them from the list and click the “Restore Selection” button. If those files still exist and you want to overwrite them, make sure the “Overwrite Existing Files” option is checked first. Otherwise, if a file with that name exists, the restore will append a number to the end of the filename. For example, the first restored version of testfile.txt will become testfile-1.txt.

Canonical Confirms Involvement in Ubuntu Linux Tablet

According to emails from Andrew Bernstein, who has emerged as the public face of the UT One tablet project, Canonical “certainly will be involved” in the production of the tablet, which will feature an Intel x86 processor.

Ubuntu Linux Tablet is Real, Pre-Orders Start Before the end of This Year
Operating System U by Andrew Bernstein — Kickstarter
The UT One runs Ubuntu Touch on a quad-core, Intel Atom Z3735D system-on-chip of the tablet-focused, 22nm Bay Trail-T generation, according to the Phoronix-reproduced UT One spec sheet.
The tablet’s SoC is said to run at 1.33GHz to 1.5GHz, and it’s accompanied by 2GB of DDR3L RAM, 16GB of storage, and a microSD slot.
The UT One’s 10.1-inch, IPS touchscreen is said to feature 1280 x 800-pixel resolution and a 16:10 aspect ratio. The screen has 10-point capacitive touch with automatic calibration.
The 254 x 170 x 10mm, 636-gram tablet is further equipped with front- and rear-mounted 2-megapixel cameras, 802.11n WiFi, Bluetooth 4.0 LE, and support for EVDO/WCDMA 3G cellular via a USB dongle, says Phoronix.
The tablet also offers a mini-HDMI port, a “USB 2.1″ port, a pair of speakers, and an audio jack. The 7900mAh battery is said to last up to eight hours and can be recharged via a DC port.

Major Performance Breakthrough Discovered For Intel’s Mesa Driver

The issue comes down to a difference in how hardware samplers were working compared to Intel’s Windows driver. LunarG passed along their findings to Intel’s Linux crew who with the help of their hardware engineers found a bit needed to make the hardware run faster.

Joey Hess Resigns From Debian, Unhappy With How It’s Changed

Joey Hess is now distancing himself from the Debian project as he resigns from his roles after being involved with Debian since 1996. In his parting remarks, Joey says his biggest regret over the past eighteen years is not speaking out against the Debian constitution.

Joey Hess played critical roles in the development of the Debian Installer, Alien, debhelper, and many other widely-used Debian components.

Re: piece of mind (Re: Moderated posts?)

Not that it would be easy to ditch systemd. But there’s a lot of FUD
going around here about sysvinit support rotting because systemd is the
default, while the fact is that Debian fFreeBSD doesn’t have systemd at
all, and all the init scripts will be kept working for that reason if
nothing else. Also, the tech committe decision was that Debian continues
to support multiple inits to the best of our ability[2]. And, the init
scripts are a relatively miniscule portion of the code in Debian, and
don’t tend to bit rot much anyway[4].

So most of our concern about being locked into systemd is that desktop
environments are coming to require it, and that systemd-shim may be hard
to keep working in the long term. But desktop environments like Gnome
were already requiring systemd before Debian switched to it; Debian
cannot hold back the tide.

ownCloud Client 1.7.0 – A big update

ownCloud Client 1.7.0 is a big release. First and foremost, it supports
new features of ownCloud 7, for example the new sharing. ownCloud Client
1.7.0 now comes with overlay icons in the most popular file managers on
the supported platforms. The icons visualize the sync- and sharing state
of synced files on the desktop.

The second great new feature of ownCloud Client 1.7.0 is selective sync.
Within a sync folder, subtrees can be excluded from sync to the client.
That makes syncing of huge data sets easier to customize.

Apart from these two lighthouse improvements this version also brings a
significant amount of bigger and smaller improvements that make syncing
with ownCloud faster, more reliable and more enjoyable.

The Reports of Compiz’s death have been greatly exaggerated, 0.9.12.0 released

Mailing List Post

This is the first release of the Compiz 0.9.12 series. It consists of mostly smaller bugfixes, as befits a mature and stable project, but also some work to port the gtk-window-decorator to GTK+-3 to benefit some of the newer DEs. We have some wonderful and dedicated community contributors to thank for keeping this project going.

Portscout ported to OpenBSD

Portscout is a popular utility used in the FreeBSD ports infrastructure
It lets port maintainers know when there’s a new version of the upstream software available by automatically checking the distfile mirror
Now OpenBSD porters can enjoy the same convenience, as it’s been ported over
You can view the status online to see how it works and who maintains what
The author is working to get all the current features working on OpenBSD, and added a few new features as well
He decided to fork and rename it a few days later

Sysadmins and systemd refugees flocking to BSD

With all the drama in Linux land about the rapid changes to their init system, a lot of people are looking at BSD alternatives
This “you got your Windows in my Linux” article (and accompanying comments) give a nice glimpse into the minds of some of those switchers
Both server administrators and regular everyday users are switching away from Linux, as more and more distros give them no choice but to use systemd
Fortunately, the BSD communities are usually very welcoming of switchers – it’s pretty nice on this side!

OpenBSD’s versioning schemes

Ted Unangst explains the various versioning systems within OpenBSD, from the base to libraries to other included software
In contrast to FreeBSD’s release cycle, OpenBSD isn’t as concerned with breaking backwards compatibility (but only if it’s needed to make progress)
This allows them to innovate and introduce new features a lot more easily, and get those features in a stable release that everyone uses
He also details the difference between branches, their errata system and lack of “patch levels” for security
Some other things in OpenBSD don’t have version numbers at all, like tmux
“Every release adds some new features, fixes some old bugs, probably adds a new bug or two, and, if I have anything to say about it, removes some old features.”

VAXstation 4000 Model 90 booting NetBSD

We found a video of NetBSD booting on a 22 year old VAX workstation, circa 1992
This system has a monstrous 71 MHz CPU and 128MB of ECC RAM
It continues in part two, where we learn that it would’ve cost around $25,000 when it was released!
The uploader talks about his experiences getting NetBSD on it, what does and doesn’t work, etc
It’s interesting to see that such old hardware isn’t necessarily obsolete just because newer things have come out since then

News Roundup

Suricata for IDS on pfSense

While most people are familiar with Snort as an intrusion detection system, Suricata is another choice
This guide goes through the steps of installing and configuring it on a public-facing pfSense box
Part two details some of the configuration steps
One other cool thing about Suricata – it’s compatible with Snort rules, so you can use the same updates
There’s also another recent post about snort as well, if that’s more your style
If you run pfSense (or any BSD) as an edge router for a lot of users, this might be worth looking into

OpenBSD’s systemd API emulation project

This story was pretty popular in the mainstream news this week
For the Google Summer of Code, a student is writing emulation wrappers for some of systemd’s functions
There was consideration from some Linux users to port over the finished emulation back to Linux, so they wouldn’t have to run the full systemd (lol)
One particularly interesting Slashdot comment snippet: “We are currently migrating a large number (much larger than planned after initial results) of systems from RHEL to BSD – a decision taken due to general unhappiness with RHEL6, but SystemD pushed us towards BSD rather than another Linux distro – and in some cases are seeing throughput gains of greater than 10% on what should be equivalent Linux and BSD server builds. The re-learning curve wasn’t as steep as we expected, general system stability seems to be better too, and BSD’s security reputation goes without saying.”
It will NOT be in the base system – only in ports, and only installed as a dependency for things like newer GNOME that require such APIs
In the long run, BSD will still be safe from systemd’s reign of terror, but will hopefully still be compatible with some third party packages like GNOME that insist on using it

GhostBSD 4 preview

The GhostBSD project is moving along, slowly getting closer to the 4 release
This article shows some of the progress made, and includes lots of screenshots and interesting graphical frontends
If you’re not too familiar with GhostBSD, we interviewed the lead developer a little while back

NetBSD on the Banana Pi

The Banana Pi is a tasty alternative to the Raspberry Pi, with similar hardware specs
In this blog post, a NetBSD developer details his experiences in getting NetBSD to run on it
After studying how the prebuilt Linux image booted, he made some notes and started hacking
Ethernet, one of the few things not working, is being looked into and he’s hoping to get it fully supported for the upcoming NetBSD 7.0
They’re only about $65 as of the time we’re recording this, so it might be a fun project to try

Lumina was committed to ports just last week, so you can go try it out on vanilla FreeBSD now as well (or on PCBSD 10.0.3)
There’s a new OS conference being held on November 25th in London, and they’re looking for people who want to give BSD presentations (it’s run by a NetBSD developer)

FreeBSD foundation’s new IPSEC project

The FreeBSD foundation, along with Netgate, is sponsoring some new work on the IPSEC code
With bandwidth in the 10-40 gigabit per second range, the IPSEC stack needs to be brought up to modern standards in terms of encryption and performance
This new work will add AES-CTR and AES-GCM modes to FreeBSD’s implementation, borrowing some code from OpenBSD
The updated stack will also support AES-NI for hardware-based encryption speed ups
It’s expected to be completed by the end of September, and will also be in pfSense 2.2

NetBSD at Shimane Open Source Conference 2014

The Japanese NetBSD users group held a NetBSD booth at the Open Source Conference 2014 in Shimane on August 23
One of the developers has gathered a bunch of pictures from the event and wrote a fairly lengthy summary
They had NetBSD running on all sorts of devices, from Raspberry Pis to Sun Java Stations
Some visitors said that NetBSD had the most chaotic booth at the conference

pfSense 2.1.5 released

A new version of the pfSense 2.1 branch is out
Mostly a security-focused release, including three web UI fixes and the most recent OpenSSL fix (which FreeBSD has still not patched in -RELEASE after nearly a month)
It also includes many other bug fixes, check the blog post for the full list

Systems, Science and FreeBSD

Our friend George Neville-Neil gave a presentation at Microsoft Research
It’s mainly about using FreeBSD as a platform for research, inside and outside of universities
The talk describes the OS and its features, ports, developer community, documentation, who uses BSD and much more

News Roundup

OpenBSD’s rcctl tool usage

OpenBSD recently got a new tool for managing /etc/rc.conf.local in -current
Similar to FreeBSD’s “sysrc” tool, it eliminates the need to manually edit rc.conf.local to enable or disable services
This blog post – from a BSD Now viewer – shows the typical usage of the new tool to alter the startup services
It won’t make it to 5.6, but will be in 5.7 (next May)

pfSense mini-roundup

We found five interesting pfSense articles throughout the week and wanted to quickly mention them
The first item in our pfSense mini-roundup details how you can stream Netflix to in non-US countries using a “smart” DNS service
The second post talks about setting ip IPv6, in particular if Comcast is your ISP
The third one features pfSense on Softpedia, a more mainstream tech site
The fourth post describes how to filter HTTPS traffic with Squid and pfSense
The last article describes setting up a VPN using the “tinc” daemon and pfSense
It seems to be lesser known, compared to things like OpenVPN or SSH tunnels, so it’s interesting to read about
This pfSense HQ website seems to have lots of other cool pfSense items, check it out

OpenBSD’s new buffer cache

OpenBSD has traditionally used the tried-and-true LRU algorithm for buffer cache, but it has a few problems
Ted Unangst has just switched to a new algorithm in -current, partially based on 2Q, and details some of his work
Initial tests show positive results in terms of cache responsiveness
Check the post for all the fine details

BSDTalk episode 244

Another new BSDTalk is up and, this time around, Will Backman interviews Ken Moore, the developer of the new BSD desktop environment
They discuss the history of development, differences between it and other DEs, lots of topics
If you’re more of a visual person, fear not, because…
We’ll have Ken on next week, including a full “virtual walkthrough” of Lumina and its applications
