How to completely remove kubuntu desktop from your Ubuntu 14.04

Say you wanna try (for fun) to experience the Kubuntu desktop environment while you run Ubuntu 14.04. Now say that after you play a while you decide you wanna go back to your familiar Ubuntu interface and you wanna get read of the Kubuntu desktop you have installed.

If you are not lucky (I usually am not!) things will get messy!

Long story short, it happened to me this morning and it took me some time to get things back to normal. Here’s what I did (hopefully it will save you some time).

CALL TO ACTION: If you do the routine and the problem is not resolved or you take some extra steps, or whatever, please leave a comment so as to help future readers 🙂 THANKS!


A. You:

sudo apt-get remove --purge kde-plasma-desktop kde-workspace kubuntu* plymouth-theme-kubuntu-logo plymouth-theme-kubuntu-text
sudo apt-get autoremove --purge && apt-get autoclean
[via: askubuntu]

Hopefully everything works fine now!

B. If you find yourself missing some system icons 😛 (sound, language, mouse, etc…) try this:

sudo apt-get remove unity-control-center
sudo apt-get install unity-control-center

How to make ClickShare work with Ubuntu

Last time I had to do a presentation was during ODI’s Train the Trainer program. One of the options we were given in order to connect to the projector was ClickShare. If you don’t know what ClickShare is, watch this!

In order to use ClickShare you have to plug it to your machine. It works like a USB flash drive so a folder opens and gives you executables for Windows and iOS. Normally you install one of them and you are good to go.

But what happens if you use a Linux machine? Well, you will probably have to use a cable because “this thing does not work well with Linux”. That’s what I was told! But it wasn’t good enough for me 🙂

So, if you happen to use Ubuntu 14.04 LTS and want to use ClickShare, all you have to do is:

  1. go here *
  2. download the Linux launcher
  3. install it to your machine
  4. open the application
  5. plug the dongle

If you are getting steady white light then you are good to go (hit it, it will normally go red and your screen should be up!).

NOTE: According to Barco, they currently support  Fedora 20 and Ubuntu 14.04 LTS. If you are using a different Linux OS this solution will probably not work but you might find some answers to this official thread **!

* 10/03/2017: Support for the Linux client has ended as it requires an enormous effort to support all the Linux distributions and their quick updates, while the usage rate of the Linux client was/is very limited. [as published on]

** 13/06/2017: Thread [] does not exist any more.

[Updated] A Windows 10 update tale!

So this is how it started…

I was already aware that Windows 10 will be freely given to previous Microsoft Windows users (even pirates!) but I felt it was not such a big deal. All the machines worth spending time to keep up to date are pretty much doing it themselves and for free since they run on linux (Ubuntu).

The only machine I own and runs on Windows is my home desktop and it runs on Windows only because other people have access to it and I value democracy 🙂

So, home PC running Windows 7, opportunity for trying Windows 10 for free… a geek’s got to do what has got to do!

FYI, the specs of my machine were:

  • Intel(R) Core(TM)2 Quad CPU Q8200 @ 2.33GHz 2.34GHz
  • 3,00 GB RAM

The update Golgotha

The core update to Windows 10 went smoothly but once I was prompted to login, Murphy jumped in!

  1. Wireless Mouse / Keyboard inaccessibility: Apparently is a known issue that Microsoft Wireless Optical Desktop 700 v2 doesn’t play well with Windows 10 (yet?). I didn’t expect every single device to work out of the box with Windows 10 but I would expect (at least) Microsoft hardware to be compatible 🙁 Anyways I changed to cable mouse / keyboard and proceeded.
  2. My DVD drive was not automatically detected ( o.O ): Thinking back, over time I have used: Windows 95, Windows 98, Windows XP, Windows Vista, Windows 7. I cannot remember a single time when a CD / DVD drive wasn’t automatically detected! Well, I guess there’s a first time for everything.
    • FIX: Should you face the same problem, this solution worked like charm for me! Don’t forget to restart 😉
  3. After logging in for the first time “special” buttons (start, notifications, search) did not work:
    • FIX: Restart (legit: right click to the windows icon and choose restart) a couple of times and everything should be fine.

The One Drive Perk

Along with Windows 10, came the One Drive suggestion. Once you have updated, the one drive application starts automatically with windows and prompts you to login or create an account if you don’t already have one. Initially I thought about skipping the whole thing since the 59 gigs in Dropbox and the 15 gigs in Google Drive are more than enough for me (at least for the time being). However, since a little more free space to the cloud never hurt anybody I decided to enable One Drive as well. I was surprised (positively) to able to subscribe using my Gmail account and not having to create a new one to Microsoft.

Everything went smoothly and now I have 15 gigs of space that I’ll probably never use 😛

Microsft Office: The unexpected Perk!

After everything was solved I decided that it was time to relax and watch a couple of Gotham episodes! Since I keep the progress of the TV Series I watch on a spreadsheet, initially I went for Libre Office! Then I remembered that I always wanted to give a shot to MS Office 2013 since my last experience was with MS Office 2010. Normally you have to pay but thanks to my academic affiliation, as a PhD candidate with the Aristotle University of Thessaloniki, I get to use it for free!

FireShot Screen Capture #248 - 'Office 365' - portal_office_com_Home#

I think academic accounts are also entitled to 1 TB One Drive space for 1 year!

The future!

Up to now, I have seen several pros and cons to Windows 10. I might get back with another post listing them. There’s also an interesting discussion about Windows 10 features & privacy to the following episode of This Week In Tech.


[Update: SEP 13th, 2015]

After less than a month of using Windows 10 the graphics card’s driver stopped working. I tried to find a compatible driver with no luck so I (guess what?) rolled back to Windows 7 🙂


How to successfully install Microsoft Office to Ubuntu

If you are a Linux enthusiast you are probably already find the title of the post strange and / or insulting. At this point I am going to have to ask you to take a deep breath and consider this…


Sometimes we are forced to use tools we wouldn’t normally just because our environment “force” us to. For example:

  1. I like using Libre Office but all the partners and employees of my firm are used to work in MS Office. I certainly can’t force the whole company to change ( at least in a day 😉 )
  2. I host Open Coffee Thessaloniki meetings where interesting people share their entrepreneurial experiences with us on a monthly basis. Most of them are using either MS Power Point or Keynote… and love effects on their presentations 🙂


I am using Linux and I want to be able to occasionally use Microsoft Office documents by preserving the Microsoft special format.


#1. Install Microsoft Office Online Apps in Ubuntu.

With this solution we are basically using the online tools connected to MS One Drive to view and edit (?) MS documents. From my experience edit doesn’t work that well 🙂 but still it’s a neat solution to easily view documents.

#2. Install MS Office via Play On Linux.

Wasn’t working (at least for me) for Ubuntu Versions before 14.04. Tried it on Ubuntu 14.04 for Office 2010 and it worked fine.


You might also want to install MS fonts for better compatibility 😉

Cheers and good luck!

Everything you need to know about WordPress 4.0, the Benny Goodman edition

Just updated to WordPress 4.0 and everything went smooth. I love the video mashup with the latest changes. It’s probably the best way to communicate the most important features to a WordPress fan 🙂

As you probably know, WordPress versions get their names from famous Jazz musicians and 4.0 is dedicated to one of my personal favorites, Benny Goodman. If you are like me and enjoy listening to swing music, I totally recommend the following duet of Benny Goodman and Peggy Lee.

I’m sorry to interrupt, but I couldn’t help but notice this young lady’s pathological attempt to project upon you her daddy issues of abandonment…

Ακολουθεί πολιτικό μήνυμα

Παρακολουθώ σχολιασμό στο facebook σχετικά με τις σημερινές εκλογές από φίλους με αυξημένη κριτική ικανότητα, μόρφωση και αρχές. Κάποιοι συζητούν για το ποιο θα πρέπει να είναι το κριτήριο με το οποίο θα ψηφίσουν. Άλλοι ποια είναι τα κριτήρια με τα οποία θα αποκλείσουν κόμματα και θα ψηφίσουν με απαγωγή σε άτοπο. Άλλοι εστιάζουν σε συγκεκριμένα κόμματα και δηλώνουν -κατά περίπτωση – είτε ότι είναι μονόδρομος για τον ψηφοφόρο, είτε ότι πρέπει πάσι θυσία να αποκλειστούν από τη διαδικασία.

Το ζήτημα είναι να μην ψηφίζεις αψήφιστα. Η πολιτική, όπως συμβαίνει και με άλλα επαγγέλματα λειτουργήματα, αντιμετωπίζεται πολύ συχνά ως επάγγελμα, αντί ως λειτούργημα που θα έπρεπε.

Σας φαίνεται φαιδρή (α) η παραπομπή σε τηλεοπτική σειρά και (β) στην Αμερική της ποτοαπαγόρευσης; Μπορεί! Αλλά ας δούμε 1 – 2 “διαχρονικές” κατά τη γνώμη μου ατάκες:

“First rule of politics, kiddo: Never let the truth get in the way of a good story.”


 “Rest assured that dry though the country may be, I am in the midst of concluding arrangements that will keep Atlantic City wet as a mermaid’s twat.”

Τάδε έφη ο θησαυροφύλακας του Atlantic City:

  • Το πρώτο απόφθεγμα αναφέρεται σε ομιλία που δίνει ο θησαυροφύλακας σε ένωση που μάχεται υπέρ του δικαιώματος της γυναικείας ψήφου, κατά τη διάρκεια της οποία αφηγείται μια ιστορία για τα παιδικά του χρόνια, που φυσικά δεν αληθεύει.
  • Το δεύτερο αφορά στην συνάντησή του λίγες ώρες πριν την επίσημη έναρξη της ποτοαπαγόρευσης με τις αρχές του Atlantic City στις οποίες ανακοινώνει ότι έχει ήδη ολοκληρώσει τις απαραίτητες ενέργειες για την επικερδή διακίνηση αλκοόλ στην πόλη από την επόμενη κιόλας μέρα.

Άσχετα με αν τα παραπάνω σας λένε κάτι ή όχι, η δική μου “πρόταση” για αυτές τις εκλογές είναι να προσπαθήσουμε να αναζητήσουμε λειτουργούς, αντί πολιτικούς.
