X2Go For Remote Linux

I listen to a couple of podcast that center around the discussion of Linux over at Jupiter Broadcasting. Recently on episode #71 of the Linux Unplugged show in their post-show they discussed X2Go, a technology similar to NoMachine. This discussion was very intriguing to me because I had been searching for a thin client type of access to a Linux machine, especially at work when working from a Windows machine when I need to work on a Linux machine. This motivated me to do some research and attempt to setup my own access to a Linux machine using X2Go. This is what I setup for myself. But keep in mind that this may not be the correct way to setup an X2Go server, this is just what worked for me.

I already had an account and a cloud server with DigitalOcean so I deployed an Ubuntu 14.04 Server and setup everything this way:

1. For Ubuntu 14.04, install repositories:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:x2go/stable
sudo apt-get update
sudo apt-get install x2goserver x2goserver-xsession

2. Install preferred Desktop Environment on the server. For Ubuntu Server 14.04, here are the steps for Mate:

sudo apt-add-repository ppa:ubuntu-mate-dev/ppa
sudo apt-add-repository ppa:ubuntu-mate-dev/trusty-mate
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install mate-desktop-environment-extras

3. Install the X2Go client on your local computer:

4. Create the session information for your connection within the X2Go client.
5. Connect.

This is a screenshot of my connection from Windows 7 to the remote server:

x2go

If I need to, I can configure the session to go full screen. I created a couple of shell scripts on my desktop to change the resolution depending on if I am connecting from my laptop or from my laptop with a external monitor connected with a different resolution.

Here is a screenshot at full screen:

Convert Video to Audio (mp3) in Linux Mint 14

I just came across a scenario where I needed to strip the audio out of a YouTube video file I had created in a Google Hangouts on Air recorded last night for The Unique Geek podcast. I found this post and it did exactly what I needed. Basically, I used the tool avconv via terminal but needed to install the codec necessary to convert to .mp3. The command to install the codec is this:

sudo apt-get install libavcodec-extra-53

I then used the following command to complete the conversion:

avconv -i video.mp4 -ab 192000 audio.mp3

Audio Static In Linux Mint No More

I’ve posted a couple of times that I have had audio static issues in my Linux Mint 14 install. I completely forgot to post that it was fixed thanks to the Linux Mint community over on Google Plus.

Here’s is what was posted there:

Hmm… being intermittent like it is, and not being external, it could be a timing problem. You could try editing /etc/pulse/default.pa, search for the line:
‘load-module module-udev-detect’
and edit it to:
‘load-module module-udev-detect tsched=0’
If there’s any options past “detect” then just comment the line out (so you can restore it if needed) and add the new setting below it.

You’ll have to reboot to be sure the new setting takes effect. If it’s a timer/scheduling problem that should take care of it, if the problem’s with Pulse to begin with.

Google Helpouts – Do You Need Help?

Google started a new program that went live today called Google Helpouts. You can get more information here. And nice intro video here:

I applied to be a part of this new service and was accepted. I will be offering Computer and Networking Assistance in Google Helpouts new service. If you need help with anything relating to technology I can offer my assistance to you. You can find my listing here (clicky the linky and image):

Android KitKat Bars Found in the U.S.A.

So, as some of you may know, Android announced at the beginning of September that their next release would be code name KitKat 4.4. Since the announcement, in conjunction with Hershey’s, a contest has started. Here is the site with the details. Also since then I’ve been looking for KitKat bars in Orlando without any luck. I’ve been watching the Android Community on Google Plus and it seems that the Android KitKat bars have been really scarce. Only a few found in Europe and South Africa and none in the United States. At least until now. I finally found them in the local Publix supermarket near me.

I posted it on Google Plus.

What is really cool is the first wrapper I opened I won, a $5 gift card to the Google Play store. However, what I found out is that it is only one entry per day. I bought four bars. I’m about to open the second one today.

Audio Static in Google Chrome in Linux Mint

An update on the last post: That fix was only temporary. After a month or so the static came back. I lived with it for a few weeks and decided to switch to Chromium again to see if the Google Hangout plugin was finally working and it is working in Chromium now. However, oddly enough, I have the occasional weird audio issue in Chromium too as heard in this video:

What is odd, as you will notice at about :20 in the video, is that the audio issue goes away. In Google Chrome, it does not go away. It is intermittent in Chromium.

This audio issue doesn’t seem to be an issue in Firefox. Which sucks since I don’t use Firefox; I prefer Google Chrome and/or Chromium.

I’m still searching for a fix.
