Ubuntu Mate 16.04 ARM

I used to write about Kubuntu when its new version was released. But for now, since my HDD is rather broken, and I have bought Raspberry Pi instead, so I want to write about Mate flavor of Ubuntu which fit to the ARM platform. Actually I want to install KDE on it, but I’m not sure about the performance.

Last month, the new long-term supported Ubuntu version was released. The main flavor with Unity has not yet brought awaited Unity 8 with Mir display server. And for my favorite flavor, Kubuntu, it has brought the newest KDE Plasma 5 for the desktop. Unfortunately I cannot play with it until I repair my PC. Maybe not only repairing, but also I ought to buy a new HDD as well.

Kubuntu: Connect to OpenVPN Server with Network Manager Applet

Okay, you’ve successfully set up a new OpenVPN server on your VPS. What’s next?

Here, i post a brief tutorial how to connect my Kubuntu desktop to OpenVPN server with the default connection manager. Previously, I have set up OpenVPN server in just one click. And after the server is up, it automagically created several OpenVPN config files for the client. I fetched them with scp.

scp root@xxx.xxx.xxx.xxx:/root/{ca.crt,client.ovpn,client1.crt,client1.key} /home/user/Projects/web/VPN

openvpn config files

OpenVPN onfig files

Before this, I didn’t have any idea how to connect to VPN with the OVPN file. But actually, it’s so easy to do that with Kubuntu network manager plasma widget.

  1. Click on the network manager widget, then click the right corner gear.
Kubuntu plasma network manager

Kubuntu plasma network manager

  1. In the window appears, click menu File, choose Import VPN. Select the OVPN file we got previously.
  1. Edit the connection, add the rest of files. Make sure that the connection type is X.509 Certificates
Add the rest of config files

Add the rest of config files

  1. Connect it.

How to write Japanese Characters in Kubuntu 15.04 using fcitx

Kubuntu 15.04 now has fcitx as the default input method for Asian languages, including Japanese. But as I installed it in English, fcitx were removed at the end of installation. Previously, I used to have ibus-anthy to write Japanese characters. Now, I give a try to fcitx-mozc for doing that. Mozc engine is developed by Google –as I know so far. And here is a post that describes how to setup fcitx-mozc in Kubuntu 15.04 for writing Hiragana, Katakana or Kanji. I quoted it from a japanese blog. Just ask Google to translate it. 😀


$ sudo apt-get install fcitx fcitx-mozc kde-config-fcitx


$ im-config -n fcitx


下部のパネルを右クリックして、[Panel Options]-[Add Widgets]で追加できるウィジェットの一覧を表示し、一番下の[入力方法パネル]をダブルクリックしてパネルに追加します。

[入力方法パネル]はパネルの右端に表示されるので、半角/全角キーを押してFcitxをオンにすると全体のアイコンが増えて左にずれ、もう一度押してFcitxをオフにすると右にずれるので、非常に鬱陶しいです。この場合、[Panel Options]-[Panel Settings]をクリックし、ポインターを[入力方法パネル]のアイコンまで移動して[入力方法パネル]という文字列が真ん中に出てきたら、左にドラッグします。


Fcitxの設定を変更する場合は、[入力方法パネル]アイコンを右クリックして[Configure Input Method]をクリックします。

How to Reinstall Ubuntu (Linux) without Repartitioning

Here’s how to reinstall Ubuntu or another Linux distro without having to lost your app settings and data. It’s useful for some cases, for instance you won’t lost your Firefox bookmarks and login session, as well as browsing history and installed add-ons. Although you can regain them all easily by the new sync feature, it can help you to save bandwidth and time.

The key to accomplish this approach is at the partitioning section when you install from USB or DVD installer. If you have /home directory in a distinct partition, then it will be easier to do. Otherwise, you may have to delete some system dirs first, instead of formatting / (root). Continue reading “How to Reinstall Ubuntu (Linux) without Repartitioning”

Kubuntu 15.04 Vivid Vervet is ready to rock

Kubuntu 15.04 has just been released. It features the new Plasma 5 Desktop, a new, sleek design of KDE UI (Ref). The Breeze theme looks refreshing, and replaces Oxygen as the default KDE theme for years. But I rather don’t like the window decor at first.

When I write this post, I was downloading the final ISO, as you can see at the image above. Recently, I’ve tried out the beta version, running on an AMD powered laptop. And as expected, there were obviously some bugs, i.e some glitches of window animation using OpenGL renderer. Also, plasma workspace got hung when I connect to WiFi network.

For the first issue, I change the OpenGL renderer to XRender, then the window animation didn’t have glitches any more. And for the latter, I didn’t know whether it was a bug or not, since it disappeared gradually. Or perhaps it was because the first issue, I think.

Looking Forward to the Release of Kubuntu 15.04

April will soon come. It means that a new Ubuntu version will be released. The most awaited one among others could be Kubuntu. It comes with the new KDE Plasma 5 desktop, a fresh new look of KDE desktop. I haven’t tried out Plasma 5 yet. And when I found out a review of Kubuntu 15.04 beta 1 on Softpedia [1], I feel cannot wait for its release next month.

KDE Connect, Link Your Android to Linux Box

[Versi bahasa Indonesia ada di halaman 2]

Recently, I had a chance to try out KDE Connect. It has KDE in its name, but you can try it on other DEs. Of course with some limitations, i.e Dolphin’s right-click menu for sending files may not available on another file manager. (I haven’t try it on another DE, though). To link your Linux to Android, you need to have KDE Connect app installed on your Android and Linux as well, and connect both devices to the same network.

You can read all about KDE Connect in its developer’s blog: https://albertvaka.wordpress.com. And these are my screenshots of KDE Connect in action:
