If you use Firefox for web development and also for regular browsing you would sooner or later realize that the Firefox addons that you use for web development is slowing down your browser and you would want to use a Firefox profile without any addons for your regular browsing. But if you do that and you want to use your developer tools once in a while you will usually have to close your Firefox session before you start a new session loading your development profile. Well not really. Here is how you can use two Firefox profiles simultaneously and not having to go through the command line every time. These instructions apply for Ubuntu but should probably work for other other GNU / Linux variants as well. You can start a new firefox session with a new profile by using the following command firefox --profile-manager -no-remote Now the next part is to add this as an option to the firefox icon that appears in your dashboard. For this the easy option is to edit /usr/share/applications/firefox.desktop. You can alternatively create a copy of the desktop file into your local users ~/.local/share/applications folder. vi /usr/share/applications/firefox.desktop Find the line "Actions=" under the [Desktop] section in the file and prefix "NewProfile;" to the value of the string. Then add a new section [Desktop Action NewProfile] Name=Open a New Profile Exec=firefox --profile-manager -no-remote OnlyShowIn=Unity; below the [Desktop] section. That is it. Now you should see a new option "Open a New Profile" when you right click on the firefox icon in your dashboard. Happy hacking.

We had to install Ubuntu 15.04 on a brand new Lenovo B40-70 laptop. Everything worked fine until we tested sound on Skype. The speakers were working fine but apparently the internal microphone was not working. After banging the head on many doors we came across this wiki page entry about troubleshooting sound issues in skype that pointed out that pulseaudio was incorrectly detecting the mono mircophone as stereo microphone. When we checked sound settings we saw that there were two channels and that they had identical amplification settings because both channels were locked together. The identical amplification on these two channels resulted in the audio input cancelling itself when processed as two separate channels. The fix was to unlock the channels and to reduce one of the channel amplification to 0% while keeping the other at 50%. I hope this helps somebody else searching for a fix for the same symptom.

I am in sound settings > Input tab, nothing by the name of channels appears there. I only get Record Sound From: Microphone (Built-in audio there) and under input volume its slightly less than 100% there. Rahul Karthik (not verified) access_time 20 Jun 2019 - 18:34 I have debain 8 installed on a new B40-70 laptop. I tried your suggestion but it didn't work. I tried many other amplification settings but all in vain. Can you suggest any other alternatives ?

Ubuntu MATE 14.04.2 is an updated build of the Ubuntu-based distribution featuring the MATE desktop environment. This release fixes a few issues that were present in 14.04.1, adds some new features and updates some packages. It is important to state clearly that Ubuntu MATE 14.04.2 is not an official Ubuntu flavour! The upside of maintaining an unofficial Ubuntu derivative is that we can roll out new features and package updates. So we did, most notably LibreOffice 4.4.1. The advantage of the newer Linux kernel is that it resolves most of the screen tearing issues some people experienced in Ubuntu MATE 14.04.1. About Ubuntu MATE Ubuntu MATE is a desktop Linux distribution which aims to bring the simplicity and elegance of the Ubuntu operating system through a classic, traditional desktop environment - the MATE desktop. MATE is the continuation of the GNOME 2 desktop environment which was used as Ubuntu's default desktop until 10.10 (when it was replaced by Unity). The project began its life as an Ubuntu "remix", but starting with version 15.04, it was formally accepted as an official member of the Ubuntu family of Linux distributions.

Raspbian (as well as NOOBS, a beginner-friendly compilation of several popular operating systems designed for Raspberry Pi). As Raspberry Pi 2 is built using the ARMv7 processor, the latest Raspbian now comes with a Linux kernel built for ARMv7: "Raspberry Pi 2 is available to buy today. Remember you'll need an updated NOOBS or Raspbian image including an ARMv7 kernel and modules from our downloads page. At launch, we are using the same ARMv6 Raspbian userland on both Raspberry Pi 1 and 2; over the next few months we will investigate whether we can obtain higher performance from regular ARMv7 Debian, or whether we can selectively replace a small number of libraries to get the best of both worlds. Now that we're using an ARMv7 core, we can also run Ubuntu. About Raspbian Raspbian is a free operating system based on Debian GNU/Linux and optimised for the Raspberry Pi hardware (the armhf processor architecture). Raspbian comes with over 35,000 packages, or pre-compiled software bundled in a nice format for easy installation on a Raspberry Pi. The initial build was completed in June of 2012, but the distribution continues to be active developed with an emphasis on improving the stability and performance of as many Debian packages as possible. Although Debian produces a distribution for the arm architecture, it is compatible only with versions later than the one used on the Raspberry Pi (ARMv7-A CPUs and higher vs the Raspberry Pi's ARMv6 CPU).
