PPA Install Skippy-XD, Exposé-like task-switcher for Xfce, LXDE

Last updated: November 10, 2013

Skippy-XD is a program for X which provides Mac OS Exposé-like features. It is a standalone application for providing a window picker with live previews (including live video) on Linux desktops that run an X server with composite support. Thus it is not part of the window manager, and the composite is not being used all the time.

To use Skippy-XD, you need Xfce (xfwm4) or a NetWM compliant window manager (LXDE, Openbox-based window managers, etc.).

This tutorial shows you how to install this task-switcher via PPA in (X)Ubuntu 13.10, (X)Ubuntu 13.04, (X)Ubuntu 12.10, (X)Ubuntu 12.04 and Linux Mint Xfce.

Mac OS X’s Exposé windows picker in Ubuntu 13.10 Xfce 4.10

Install Skippy-XD:

The Skippy-XD code has been released in 2004, and only slightly improved in 2011. Currently Skippy-XD is under (somewhat) active development and the latest GIT code is available in the PPA below.

Press Ctrl+Alt+T on keyboard to open terminal. When it opens, run commands below one by one to install it from PPA:

sudo add-apt-repository ppa:landronimirc/skippy-xd-daily

sudo apt-get update

sudo apt-get install skippy-xd

Once installed, start the daemon via:

skippy-xd --start-daemon &

And activate the windows picker:

skippy-xd --activate-window-picker

Add Keyboard Shortcuts for Skippy-XD

Typically, it is helpful to set up keyboard shortcuts for skippy-xd. For Xfce4:

1. Go to Settings Manager -> Settings Editor -> xfce4 keyboard shortcuts.

2. Click on New, and type in:

Property: /commands/custom/<Alt>1 #You may change <Alt>1 to other key combination.
Type: String
Value: skippy-xd --activate-window-picker

xfce4 add custom shortcut key

Auto start Skippy-XD daemon at login:

Go to Settings Manager -> Session and Startup -> Application Autostart. Click on Add button, type in name and command skippy-xd --start-daemon

Take screenshot of Login Screen in Ubuntu, Elementary & Pear OS

Last updated: November 10, 2013

This simple tutorial shows you how to capture screenshot of the LightDM / GDM login screen in Ubuntu, Elementary OS, or Pear OS.

Besides installing your system as Virtualbox or Vmware Guest OS, we can follow the steps below to capture and share our login screens.

1. Press Ctrl+Alt+T on your keyboard to open terminal. When it opens, run command blow to check out your display manager:

cat /etc/X11/default-display-manager

handbook@handbook-1310:~$ cat /etc/X11/default-display-manager 
/usr/sbin/lightdm

By default:

Ubuntu Unity and Elementary OS Luna uses LightDM
Pear OS 8 and Ubuntu Gnome uses GDM

2. Check out the value of $DISPLAY:

echo $DISPLAY

handbook@handbook-1310:~$ echo $DISPLAY
:0

3. Now create a simple script

echo 'sleep 20; DISPLAY=:0 XAUTHORITY=/var/run/lightdm/root/$DISPLAY xwd -root' > /tmp/shot.sh

You may change:

20 : the seconds of delay.
:0 : the value of $DISPLAY. In my Pear OS 8, the value of $DISPLAY changes every login ($DISPLAY=$DISPAY +1).
lightdm : the display manager.

4. Press Ctrl+Alt+F1 and log into TTY1.

5. Run command below to start the script:

sudo bash /tmp/shot.sh >/tmp/shot.xwd

6. Return to GUI mode by pressing Ctrl+Alt+F1.

7. Logout by normal way. While you can see login screen, wait for some seconds.

8. Login by normal way. Install imagemagick if you don’t have it installed yet.

sudo apt-get install -y imagemagick

9. Run command below and finally you can check out the image under user Pictures folder.

convert /tmp/shot.xwd ~/Pictures/loginscreen.png

How to Install Pear OS 8 from USB Stick

Last updated: July 25, 2014

Pear OS 8, a Linux distribution based on Ubuntu 12.04 Precise and inspired by iOS7 has been released today. It aims to be reliable, efficient and innovative.

It’s hard to run Virtualbox Guest OS on my old laptop, so I installed Pear OS 8 as a quintuple-boot. Now I have Ubuntu 13.10 Saucy, Linux Mint 15 Olivia, Elementary OS Luna, Windows 7 and Pear OS 8.

Tutorial Objectives:

Install Pear OS 8 from USB Stick
Enjoy!

Preparation:

Format your USB Stick (2G+) to FAT32 format without ‘Quick Format’ enabled.
Download Pear OS 8 from its ~~official download page~~

Create bootable Pear OS USB from ISO image

The first step is going to burn the Pear OS iso into USB, so that you can boot up and start the install wizard. There are a few tools can do this job, here I used Unetbootin.

1. Download unetbootin executable from unetbootin.sourceforge.net. For Ubuntu, you can also install it in Ubuntu Software Center.

2. Plug-in your USB stick, then open Unetbootin. Choose Diskimage and browser to select the iso image.

3. Click on OK button and wait a few minutes for the burning process.

Install Pear OS 8 from the bootable USB

Insert the USB stick into the target computer. Start the machine and choose to boot up via USB in BIOS. You’ll see a blue background with a few options, choose to boot with ‘Start the installer directly’.

When you’re in the live system, you can totally follow this Ubuntu step by step installation guide to install Pear OS 8 on your machine.

NOTE: If you have Ubuntu based system previously installed as dual or triple boot, you may choose to install boot loader to local partition rather than whole hard disk.

Install Nvidia 304.116 for Legacy GPUs in Ubuntu, Linux Mint

Last updated: November 8, 2013

The latest Nvidia Legacy GPU driver 304.116 has improved compatibility with recent Linux kernels. Here’s how to intall it if you have an old graphics card that is no longer supported in the regular NVIDIA Unified Graphics Driver.

What’s New in Nvidia 304.116:

Updated nvidia-installer to consider the “libglamoregl.so” X loadable extension module to be in conflict with the NVIDIA OpenGL driver. This module can cause the NVIDIA libGL to be loaded into the same process (the X server) as the NVIDIA libglx.so extension module, which is not a supported use case.

Improved compatibility with recent Linux kernels.

Updated the NVIDIA OpenGL driver to write temporary files to $TMPDIR if it is set, instead of unconditionally writing to /tmp.

Updated a fallback of writing temporary files to $HOME/.nvidia to use $HOME/.nv instead, as the latter path is already used for other NVIDIA driver related files.

Install Nvidia 304.116:

Before getting started, remove previous installed Nvidia proprietary drivers in terminal (Ctrl+Alt+T):

sudo apt-get purge nvidia-current

Then download the driver from official links below:

Nvidia 304.116 for Linux 32 bit

Nvidia 304.116 for Linux 64 bit

Follow the steps below to install it:

1. Press Ctrl+Alt+F1 to switch to command console. Login with your username and pasword.

2. Kill the graphic session with the command below:

For default LightDM:

sudo service lightdm stop

For Gnome GDM:

sudo service gdm stop

For Linux Mint MDM:

sudo service mdm stop

3. Give executable permission to the installer:

chmod +x ~/Downloads/NVIDIA-Linux-*-304.116.run

4. Start the installer and follow on screen prompts:

sudo sh ~/Downloads/NVIDIA-Linux-*-304.116.run

5. Restart and done.

sudo reboot

If for some reason the driver does not work properly for you, re-do step 1 & 2 and followed with command below to uninstall this driver:

sudo sh ~/Downloads/NVIDIA-Linux-*-304.116.run --uninstall
