Last updated: October 4, 2014

This quick tutorial shows you how to install the latest release of Quassel IRC client in Ubuntu 14.10, Ubuntu 14.04, Ubuntu 12.04 and derivatives via PPA.

Quassel is a modern, cross-platform, distributed KDE / Qt IRC client. One (or multiple) client(s) can attach to and detach from a central core. It’s much like the popular combination of screen and a text-based IRC client such as WeeChat, but graphical.

While Ubuntu 14.04 Software Center provides Quassel 0.10, the latest release has recently reached 0.11. See what’s new:

changes in v0.10.1:

Fix buffer hotlist sorting
Split CTCP messages if they’re too long
Make database problems more obvious
Fix backlog loading for QuasselDroid
Properly save the toolbar state on Mac OSX
Fix a crash with KDE’s network detection
Various other fixes

changes in v0.11.0:

New build requirements: C++11 capable compiler (gcc 4.7+, clang 3.3+, MSVC 2013+), cmake 2.8.9+
Full support for Qt 5.2+ in addition to Qt 4.6+
Completely revamp the build system, making use of “new” CMake features

Install Quassel IRC Clien via PPA:

Thanks to Michael Marley, a PPA repository has been created with the latest stable builds of Quassel packages for Ubuntu 14.10, Ubuntu 14.04, Ubuntu 12.04 and derivatives.

1. Press Ctrl+Alt+T on keyboard to open terminal. When it opens, run the command below to add the PPA:

sudo add-apt-repository ppa:mamarley/quassel

Type in your user password when it asks. Note that there is no visual feed back when you’re typing a password.

2. Then update and install the client:

For KDE build, run:

sudo apt-get update; sudo apt-get install quassel

For Qt build, run:

sudo apt-get update; sudo apt-get install quassel-qt4

Once installed, open the irc client from Unity dash or application menu and you can receive future updates by running regular update via Software Updater.

Ubuntu 14.04 Tip: Remove Unwanted Players From Sound Menu

Last updated: October 2, 2014

Have tried multiple media players in Ubuntu and found that the sound menu is full of player controls? Well, below I’ll tell how to clean it up by removing unwanted players from the menu.

Remove unwanted players from sound menu

To get started, we need a simple tool called dconf-editor. If you don’t have it on your system, click the link below to bring up Ubuntu Software Center and click the install button.

click install dconf-editor

Once you have it installed, open the tool from Unity dash or left launcher. When dconf-editor opens, navigate to com -> canonical -> indicator -> sound.

Double click the closed brackets next to ‘interested-media-players’ and remove the names of the players ended with .desktop.

For me, after removing ‘tomahawk.desktop’, ‘pragha.desktop’, ‘gnome-music.desktop’, ‘rhythmbox.desktop’, ‘pithos.desktop’, ‘nuvolaplayer.desktop’, only VLC media player is left under the sound menu.

If you later launch a player after you “removed” it, it will be added back to the sound menu automatically. To prevent this happens, add it into blacklisted-media-player.

In my case, pragha and gnome music player will be never listed in the sound menu, even you’re listening with one of them.

That’s it. Enjoy!

3 Ways to Create Wifi Hotspot in Ubuntu 14.04 (Android Support)

Last updated: November 15, 2014

Dear readers, I’ve found a new way to create wireless hotspot in Ubuntu, AP mode with Android devices support, using Unity’s Network Manager.

After this tutorial, I’ve found 3 ways to create wifi hotspot in ap mode:

Using Ap-hotspot, an open-source app from github: see this post.
Using KDE connection editor, see the post.
Using Unity’s Default Network Manager with a little hack. See below

Below I will show you how to use Unity’s default network manager to create a wireless hotspot with Android devices support, tested in 64-bit Ubuntu 1404 with Nexus 4 and Sumsung Galaxy ace3.

1. Disable WIFI and plug in an internet cable to your laptop so that your Ubuntu is connect to a wired internet and wireless is disabled.

2. Go to Network Icon on top panel -> Edit Connections …, then click the Add button in the pop-up window.

3. Choose Wi-Fi from the drop-down menu when you’re asked to choose a connection type:

4. In next window, do:

Type in a connection name. The name will be used later.
Type in a SSID
Select mode: Infrastructure
Device MAC address: select your wireless card from drop-down menu.

5. Go to Wi-Fi Security tab, select security type WPA & WPA2 Personal and set a password.

6. Go to IPv4 Settings tab, from Method drop-down box select Shared to other computers.

When done, click the save button.

After above steps, a configuration file created under /etc/NetworkManager/system-connections directory. File name is same to the connection name you typed in step 4.

Now press Ctrl+Alt+T on keyboard to open terminal. When it opens, paste the commands below and hit enter to edit the configuration file:

gksu gedit /etc/NetworkManager/system-connections/wifi-hotspot

Replace wifi-hotspt with the connection name you typed in step 4.

When the file opens, find out the line mode=infrastructure and change it to mode=ap. Finally save the file.

When everything’s done, enable WIFI from Network Manager icon on the panel. It should automatically connect to the hotspot you created. If not, select “Connect to Hidden Wi-Fi Network …” and select it from the drop-down box.

Now you can search and connect the access point from your Android mobile and enjoy!

Nvidia 343.22 Released, How to Install it in Ubuntu 14.04/12.04

Last updated: September 19, 2014

Nvidia has just announced a new version of graphics driver 343.22 for Linux with new GPUs support and various fixes.

According to the release highlights, Nvidia 343.22 added support for GeForce GTX 970 and GTX 980, removed support for G8x, G9x, and GT2xx GPUs, and motherboard chipsets based on them. Ongoing support for new Linux kernels and X servers, as well as fixes for critical bugs, will be included in 340.* legacy releases through the end of 2019.

The new drive contains various fixes and/or new features:

Fixed a bug that prevented the “sync to vblank” setting from being honored for EGL applications.
Fixed a bug that could cause some OpenGL programs to encounter out of memory during a mode switch.
Fixed a bug that prevented the NVIDIA OpenGL driver from honoring the __GL_SHADER_DISK_CACHE_PATH environment variable.
Fixed a bug that caused disabled displays to be implicitly included in the target selection for some queries and assignments on the nvidia-settings command line interface, in the absence of any explicit target selection.
Added a new attribute to the NV-CONTROL API to query the current utilization of the video decode engine.
Fixed a bug where the Exchange Stereo Eyes setting in nvidia-settings didn’t work in certain stereo configurations.
Worked around a Unigine Heaven 3.0 shader bug which could cause corruption when tessellation is enabled by implementing an application profile that uses the “GLIgnoreGLSLExtReqs” setting. See the documentation for the __GL_IGNORE_GLSL_EXT_REQS environment variable for more details.
Fixed a memory leak when destroying EGL surfaces.
Added support for multiple simultaneous EGL displays.
Fixed a bug that could cause nvidia-installer to unsuccessfully attempt to delete the directory containing precompiled kernel module interfaces, on packages prepared with –add-this-kernel.
Updated nvidia-installer to log uninstallation to a separate file from the installation log, and to attempt uninstalling previous driver installations using the installer program from the previous installation, when available.

Install or Upgrade to Nvidia 343.22 in Ubuntu:

NOTE: Ubuntu provides “nvidia-current” driver, available in Software Center, which may interact better with your distribution’s framework, and you may want to use this rather than NVIDIA’s official package.

There are two ways installing this driver in your Ubuntu system, using the official .run installer or a third-party PPA repository.

To install Nvidia 343.22 via official installer:

1. Press Ctrl+Alt+T to open terminal, run command below to download the driver:

For 32-bit system, run:

cd ~/Downloads/ && wget http://us.download.nvidia.com/XFree86/Linux-x86/343.22/NVIDIA-Linux-x86-343.22.run

For 64-bit system, run:

cd ~/Downloads/ && wget http://us.download.nvidia.com/XFree86/Linux-x86_64/343.22/NVIDIA-Linux-x86_64-343.22.run

2. , run command to remove the previous driver and install latest update-dev package:

sudo apt-get purge nvidia*; sudo apt-get install nvidia-331-updates-dev

When done, restart your computer.

3. When back, press Ctrl+Alt+F1 (or F2~F6) to switch to command console and log in with your user name and password.
There will no visual feedback when typing a password, just type in mind and hit enter.

4. When you’re logged into command console, stop the graphics session by running the command below:

sudo service lightdm stop

For Ubuntu Gnome edition and Linux Mint, you may replace ligthdm with gdm or mdm

5. After the graphics session closed, you can now starts the official Nvidia installer, by running below commands:

chmod +x ~/Downloads/NVIDIA-Linux-*-343.22.run && sudo sh ~/Downloads/NVIDIA-Linux-*-343.22.run

Follow the onscreen prompt and done!

6. (Optional) To uninstall this driver, run below command in console:

sudo sh ~/Downloads/NVIDIA-Linux-*-343.22.run --uninstall

To install the driver from PPA repository (easier way):

First check out the PPA page to see if the packages are ready: xorg-edgers PPA. Check out the package version of “nvidia-graphics-drivers-343”.

Once the driver is made into the PPA, you can run below commands one by one to install it in Ubuntu 14.04 or Ubuntu 14.10:

sudo add-apt-repository ppa:xorg-edgers/ppa

sudo apt-get update

sudo apt-get install nvidia-343

That’s it. Enjoy!

sudo add-apt-repository ppa:niko2040/e19 sudo apt-get update sudo apt-get install enlightenment terminology

Thanks to batden, there’s now a bash script to make it easy to install / upgrade / uninstall the E19 (git version) in Ubuntu 14.04 LTS. All you need to do is download & install the script and answer on screen prompts during the installing process.

1. To download the script, right-click the link below and click “Save link as …” and save the file nineteen.sh to Downloads folder..

~~Right-click me and select ‘Save link as …’~~

You can also download the script from the ubuntuforums thread.

2. After you downloaded the script, make it executable and run it.

To do so, press Ctrl+Alt+T on keyboard to open the terminal. When it opens, run the commands below one by one:

cd ~/Downloads/ && chmod +x nineteen.sh && ./nineteen.sh

3. When the script starts, type a number to select install, update, or uninstall E19 (see above picture.) and hit Enter.

After that, it will pop up a information dialog and then ask you to insert your user password. Not that, terminal does not give visual feed back when typing a password, just type in mind and hit enter.

4. After that, the script will update & upgrade your system, download all Enlightenment packages, and finally compile them on your system. Depends on your internet connection, the process will cost a few minutes.

During this period of time, it will ask two or three questions, so don’t go too far away!

5. When everything’s done, you should see something like below.

Restart your computer and select log in with Enlightenment when you’re at Unity Greeter and enjoy!

Tip: due to bug, options for “after idle” and “at” are grayed out. I got it fixed in my 64-bit Ubuntu 14.04 by accident. See what I did:

Downloaded & installed the complexshutdown_0.5_all.deb
Run the app for a while and found that “after idle” and “at” options not available.
Removed complexshutdown 0.5 by running below command in terminal:
```
sudo apt-get remove complexshutdown
```
Installed the complexshutdown_0.4_amd64/i386.deb (available in above link)
Run the app and found that “at” option worked, but “after idle” not.
Finally I removed complexshutdown_0.4 and reinstalled the 0.5 version. Found that all works!
