For details, release the announcement.

How to install/upgrade Blender in Ubuntu:

Blender website provides pre-built binary packages for Linux 32-bit/64-bit, you may read this post to install the official package and make a shortcut icon for Ubuntu desktop.

Since the official package is not well integrated with Ubuntu desktop, you can alternatively install Blender from Thomas Schiex’s PPA, and receive future updates through Software Updater.

To do so, run below commands one by one in a terminal (Ctrl+Alt+T) window:

sudo add-apt-repository ppa:thomas-schiex/blender

sudo apt-get update

sudo apt-get install blender

Note that there might be a small delay before a new release to be made into the PPA. You may check out the PPA web page for the Blender version.

In addition, to associate .blend files with Blender go to file’s context menu (right-click menu) -> Properties -> Open With tab -> select Blender software from the list and finally click the Set as default button.

Install Hot Corners Plugin for Xfce4 Desktop in Ubuntu 14.04/15.04

Last updated: July 14, 2017

XFCE4 desktop now has a hot-corner panel plugin that provides an easy way for users to set hot corner action, though there’s already a Gnome app brightside works on Ubuntu with Xfce.

XFCE4 HotCorner Plugin is a new project created one week ago. It currently supports the following operation in primary display:

xfdashboard
toggle desktop
start screensaver
turn off monitor
run custom command

It also provides an option to disable hot corner when active window is fullscreen.

Install HotCorner Plugin in (X)Ubuntu:

Update: Thanks to Jackson Doak, the most recent packages have been made into Xubuntu Extras PPA. So far, Ubuntu 15.10, Ubuntu 15.04, and Ubuntu 14.04 (Xfce 4.12 is not required) are supported.

To install the HotCorner plugin and receive future updates, run below commands one by one in a terminal emulator:

sudo add-apt-repository ppa:xubuntu-dev/extras

sudo apt-get update

sudo apt-get install xfce4-hotcorner-plugin

For those who don’t want to add PPA, grab the .deb package from ~~launchpad page~~.

This plugin ~~requires XFCE 4.12~~. For (X)Ubuntu 14.04 and (X)Ubuntu 15.04 and Mint 17 users who are still running with old Xfce desktop, you may first read this guide to upgrade to Xfce 4.12

To install the plugin, select download one of below packages that matches your OS type (32-bit=i386 or 64-bit=amd64)

xfce4-hotcorner-plugin_0.0.2-0ubuntu1~15.10_amd64.deb
xfce4-hotcorner-plugin_0.0.2-0ubuntu1~15.10_i386.deb

from the ppa packages download page:

~~download xfce4-hotcorner-plugin (.deb)~~

Then double-click to install the package via Software Center, or install it via dpkg command.

NOTE 1: the packages were built against Ubuntu 15.10 Wily, but they work on old Ubuntu releases (tested in 14.04) running with Xfce 4.12.

NOTE 2: Xubuntu Extras PPA also provides the packages for this plugin, ~~but it’s an old release with bugs at the moment of writing this post.~~

After installing the plugin, go to Xfce4 panel preference window and add HotCorner plugin to panel:

Finally set your hot corners actions from the plugin’s preference window and enjoy!

Change the Minimum Password Length in Ubuntu 14.04

Last updated: June 28, 2015

Ubuntu 14.04 requires a minimum password length of 8 characters, as well as complexity check by default, though you can set a short password while installing Ubuntu.

The /etc/pam.d/common-password file handles password-related configurations. If you want to set a short password and disable complexity check, edit the file via below steps:

1. Open terminal from the Dash, Launcher or by pressing Ctrl+Alt+T on keyboard. When it opens, run below command to edit the file:

sudo nano /etc/pam.d/common-password

Type in your user password when it asks

2. When the file opens in the terminal screen, scroll down and find out the line:

password     [success=1 default=ignore]    pam_unix.so obscure sha512

To set minimum password length, add minlen=N (N is a number) to the end of this line.

To disable complexity check, remove “obscure” from that line.

After that, press Ctrl+X and then type Y to save changes and finally press Enter to exit editing.

After all, change your password via passwd USERNAME command.

A simple and beautiful WhatsApp desktop client has been created recently, available for Linux, Windows, and OS X. It’s an open-source and unofficial client based on WhatsApp Web.

Besides the basic WhatsApp features (e.g., group chats, send photos & videos, and share locations), this unofficial WhatsApp for desktop also features:

Badge with the number of notifications in the dock/taskbar (OS X and Windows)
Auto-launch on OS startup (OS X, Windows)
Native notifications (all platforms)
System tray icon (OS X, Windows)
Open links in browser or new window

Before installing this software, you may first read the following DISCLAIMER from its project page:

This project does not attempt to reverse engineer the WhatsApp API or attempt to reimplement any part of the WhatsApp client. Any communication between the user and WhatsApp servers is handled by WhatsApp Web itself; this is just a native wrapper for WhatsApp Web, more akin to a browser than any WhatsApp software.

To install it, select download linux32.deb or linux64.deb that matches your os type (32-bit or 64-bit) from the link below and then click install via Software Center or Gdebi package installer.

How to Install/Upgrade to Kernel 4.1 in Ubuntu, Linux Mint

Last updated: July 28, 2015

Linux Kernel 4.1, a new kernel series, was released over the night by Linus Torvalds. He wrote on the Linux kernel mailing list:

So after a *very* quiet week after the 4.1-rc8 release, the final 4.1 release is now out.

I’m not sure if it was quiet because there really were no problems (knock wood), or if people decided to be considerate of my vacation, but whatever the reason, I appreciate it. It’s not like the 4.1 release cycle was particularly painful, and let’s hope that the extra week of letting it sit makes for a great release. Which wouldn’t be a bad thing, considering that 4.1 will also be a LTS release.

Anyway, since rc8 we’ve had truly small changes, mainly some final driver fixups (HDA sound, drm, scsi target, crypto) and a couple of small misc fixes. The appended shortlog is probably one of the shortest ones ever. I’m not complaining.

And this obviously means that the merge window for 4.2 is open.

Linus

What’s New in Kernel 4.1:

Some of highlights for the Linux 4.1 kernel (by Michael Larabel):

Significant performance improvements for certain hardware as well as power consumption/efficiency improvements for select Intel hardware.
Nouveau ships with GeForce GTX 750 acceleration support that doesn’t require the manual extracting/setup of any non-redistributable firmware blobs.
Intel XenGT vGPU support for those wanting Intel graphics acceleration support from Xen guests. The KVM support is still being developed.
Radeon DisplayPort MST support.
EXT4 file-system encryption thanks to work done by Google in looking to add file-system-level EXT4 encryption for Android.
Better RAID 5/6 support with MD RAID.
Improved laptop support from major vendors along with better Chromebook Pixel 2 support.
Continued bring-up of Intel Skylake support within Linux. Skylake is still on course for launching later this year.
ACPI support for AArch64 / 64-bit ARM.
Many other changes.

Install/Upgrade to Kernel 4.1 in Ubuntu, Mint:

The Ubuntu Kernel Team has made the binary packages for this kernel release, available for download at link below:

Download Kernel 4.1 (.DEB)

First check out your OS type, 32-bit (i386), 64-bit (amd64), or armhf, then download and install the packages below in turn:

linux-headers-4.1.0-xxx_all.deb
linux-headers-4.1.0-xxx-generic_xxx_i386/amd64/armhf.deb
linux-image-4.1.0-xxx-generic_xxx_i386/amd64/armhf.deb

After installing the kernel, you may run sudo update-grub command in terminal (Ctrl+Alt+T) to refresh grub boot-loader.

If you need a low latency system (e.g. for recording audio) then download & install below packages instead:

linux-headers-4.1.0_xxx_all.deb
linux-headers-4.1.0-xxx-lowlatency_xxx_i386/amd64.deb
linux-image-4.1.0-xxx-lowlatency_xxx_i386/amd64.deb

For Ubuntu Server without a graphical UI, you may run below commands one by one to grab packages via wget and install them via dpkg:

For 64-bit system run:

cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.1-unstable/linux-headers-4.1.0-040100-generic_4.1.0-040100.201506220235_amd64.deb

Install the Official Elementary Music Player in Ubuntu 15.04, 15.10

Last updated: June 21, 2015

Noise, the official music player of Elementary OS, is a fast and beautiful GTK3 audio player with a focus on music and libraries. It handles external devices, CDs, and album art. Noise utilizes Granite for a consistent and slick UI.

Elementary OS Team has created a few PPAs on launchpad.net so users can easily install and test some Elementary applications on Ubuntu desktop. And here’s how to install Noise music player in Ubuntu 15.04, or Ubuntu 15.10.

Noise in Ubuntu 15.04

1. Open terminal from the Dash, App Launcher, or by pressing Ctrl+Alt+T on keyboard. When it opens, run command to add the Elementary OS daily ppa:

sudo add-apt-repository -y ppa:elementary-os/daily

2. After adding the PPA, refresh your system repository cache and install the music player via 2 commands:

sudo apt-get update

sudo apt-get install noise

3. Finally, you have to remove the PPA since it contains some unstable and EOS only applications. To do so, run:

sudo add-apt-repository -r ppa:elementary-os/daily && sudo apt-get update

4. (Optional) If you want to remove this music player, simply run:

sudo apt-get remove noise

Tip: Due to a bug related to the Unity overlay scrollbars, there’s a background issue which can be fixed by running below command to edit the launcher file of Noise:

gksudo gedit /usr/share/applications/noise.desktop

Install gksu from Software Center if the command doesn’t work. When the file opens, change the value of Exec to env LIBOVERLAY_SCROLLBAR=0 noise %U so it look likes:

That’s it.

Install MuPDF in Ubuntu:

1. Open terminal from the Dash, Application Menu, or by pressing Ctrl+Alt+T on keyboard. When it opens, run command to add PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/apps

2. After adding the PPA, open Software Updater to automatically check for updates

After checking for updates, you’ll see MuPDF in the list available for upgrade if you have a previous version installed.

If you don’t have a previous release installed in your system, install it via Synaptic Package Manager or by running below command in terminal:

sudo apt-get install mupdf mupdf-tools

Once installed, open PDF/XPS files using MuPDF from their context (right-click) menu. For key bindings and other options, run man mupdf in terminal.

To set MuPDF as default viewer, go to PDF file’s context menu -> Properties -> Open With tab -> select the viewer from list and click Set as default button.
