Enable JPEG-XL support in Ubuntu 24.10
The recently released Ubuntu 24.10 ships with Gnome 47, but doesn't include the default Gnome wallpapers by default. You can manually install these wallpapers by installing gnome-backgrounds using sudo apt install gnome-backgrounds. However you will notice that many wallpapers will only render one solid color and not the actual background image. This is because many wallpapers in the gnome-background package are now in .jxl (JPEG-XL) format, and unfortunately Ubuntu doesn't have support for this file format enabled by default.
Luckily, there's an easy fix. Starting with Ubuntu 24.10 you can enable JPEG-XL support by installing the libjxl-gdk-pixbuf package so that you can enjoy the default Gnome wallpapers in Ubuntu 24.10.
- Install the Gnome backgrounds:
sudo apt install gnome-backgrounds - Install JPEG-XL support:
sudo apt install libjxl-gdk-pixbuf - Log out and log back in again and go to Settings > Appearance. You can now see the default Gnome wallpapers available here.
That's it!
Some Fritz!Box modems might have been hijacked
TL;DR: Fritz!Box devices using custom DNS resolution services like Pihole or Adguard might have been compromised by DNS hijacking and using those Fritz!Box devices might be unsafe, especially for Windows users. Update: I updated the article to downscale the severity of the situation. After posting the article on HN, I came to the conclusion based on comments from other HN commenters that the Fritz!Box will not externally resolve *.fritz.box domain names. This it not the case if you use your own
