Fixing nm-applet (Network Manager Applet) icon in LXDE/XFCE/MATE Desktop

If we use MATE or LXDE, we probably often got a bug in Network Manager Applet (nm-applet) particularly if we use a mobile broadband connection. The bug is there is no icon when the connection is established. What does really cause this ? Well, apparently, the cause is very small, actually not a big deal. The cause is in the crappy default gnome icon theme (yeah, tango icon theme and the gnome icon theme is the ugliest icon themes ever).

To fix this, just follow these simple steps :

Choose a good icon theme for 24 pix panel size

(I took an icon from /usr/share/icons/Faenza/status/24/nm-signal-100.png
Rename the icon to be nm-wwan-tower.png
Move the icon into the system

sudo mv nm-wwan-tower.png /usr/share/icons/hicolor/22x22/apps
Logout login, or reboot the system, and last, try it by connecting to the Internet.

It is also --the most important thing-- very easy to install, even for beginners. But for some couple of years, because of technical reason, I stopped to play around with the Ubuntu releases. I stood for KDE Neon and became my primary OS because of its simplicity and the look. Few days ago Ubuntu has released its newer version, Ubuntu 19.04 codenamed Disco Dingo. I'm yes impressed by the progress Ubuntu developer has made, especially the way they arrange the GNOME desktop to match the Ubuntu theme. But the most interesting flavor of this release is Ubuntu Kylin. It's an official Ubuntu flavor, designed for Chinese People with its own...

How To Speed Up Your KDE Plasma Desktop (KDE4)

KDE is one of the oldest desktop environment in Linux. While GNOME (the other desktop that as old as KDE) is trying to built its own style of user interface, KDE from the beginning seems to mimics the Microsoft Windows' "classic" user interface. Thus, KDE has its own user base, especially for them who still in love with the Windows' philosophy : a simple desktop, with a single taskbar in the bottom, and a start menu in the left. Personally, I love KDE. It's gorgeous and eyecandy. But sometimes, I feel KDE is little bit slow in my older hardwares. So, after some experiences, I've found some tweak how to make KDE Plasma Desktop Runs Faster . 1. Change The Compositing Engine Go to System Settings>Desktop Effect>Advanced , and change the Compositing type from OpenGL 2.0 to XRender. 2.

And the most used device to use broadband connection is USB Modem (GSM/CDMA), and one of the most used brands is Huawei, a world-recognized Chinese manufacture that focuses to produce great networking devices (modems, router etc).
