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.

xfce hotcorner plugin

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.

hotcorner plugin for xfce4 desktop

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:

hotcorner-plugin

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

ubuntu-tips

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

edit-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.

set-password-length

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.
