Loupe is the core image viewer app for GNOME since version 45, but it’s so far not made default in Ubuntu.
It’s a fully adaptive image viewer that supports mobile form factors. It’s touch-friendly that supports 2-finger swipe left/right to navigate, 2-finger pinch/stretch to zoom out/in, and 2-finger gestures to rotate images.
Other features of Loupe include fast GPU accelerated image rendering, tiled rendering for vector graphics, sandboxed image decoding, and more.
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. It rarely needs to scan through its entire database, and most I/O is done asynchronously, but the results are synchronized.
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.

Want to open (or export to) .jxl files? Here’s how to enable the image format support in Ubuntu and Debian.
JPEG-XL (.jxl) is a royalty-free raster-graphics image format supports both lossy and lossless compression. It includes features such as animation, alpha channels, layers, thumbnails, and has better compression efficiency (60% improvement) comparing to JPEG.
GNOME favors JPEG-XL as background wallpaper in next version 46. But, Ubuntu now does not support the image format due to lack of a build dependency.
If you have some .jxl images stored in Ubuntu, then here’s how to make them work in image viewer, GIMP, and maybe other graphical apps.
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!
