This tutorial shows how to use locate command to quickly find files in your Linux system.
In Ubuntu Linux, the locate command is provided by the plocate package. It’s very fast command line search tool, that can find all files in the system matching the given pattern.

Most importantly plocate is easy to use! I regularly use it to search app icon images that are in use in most pages of this website.

This simple tutorial shows how to install and use Kvantum theme engine to change themes for your Qt5 and Qt6 applications in Ubuntu 20.04 and Ubuntu 23.10.
GNOME Desktop uses GTK toolkit for its applications and KDE/LxQt uses Qt toolkit instead. These apps work on each other desktop environment, but may NOT look native.
To unify the look and feel, Fedora Qt developer team has QGnomePlatform, adwaita-qt, and QAdwaitaDecorations projects to make Qt apps look better in GNOME. So far, only QAdwaitaDecorations is in active development for implementing Adwaita-like window header and border for Qt apps.
For Qt app window color, buttons, and other components, Kvantum is good choice to do the job.

This simple tutorial shows how to get rid of the “Mobile Broadband” menu option from the upper right system status menu in GNOME Desktop.
GNOME, the default desktop in Ubuntu and Fedora Workstation, has built-in support for mobile broadband. If your computer (usually laptop) has a built-in SIM card slot, then it will show you the “Mobile Network” page in Settings and “Mobile Broadband” option in upper right menu.
For those who rarely use this feature, the option is useless but makes the menu longer. So, it’s a good choice to completely disable it!
