Fedora Linux 45 Internationalization Test Day kicks off Today
The Fedora QA team has launched a week-long test day to verify internationalization support ahead of the Fedora 45 release. Running from September 7 through September 13, 2026, the effort is organized by Kamil Paral and asks testers worldwide to check font rendering, input methods, and locale handling across every supported desktop environment.
If you've ever wrestled with right-to-left text alignment or watched your CJK characters render as tofu on a Linux desktop, you know internationalization is where operating systems often go to die. It's unglamorous work, but it's also the difference between a distro that works for you and one that's essentially unusable. Fedora is trying to catch those regressions before they ship.
What's on the test list
The scope covers the full breadth of Fedora 45's desktop offerings. You'll be testing GNOME, KDE Plasma, XFCE, LXQt, Cinnamon, and any other graphical spins available at the time. But the checklist doesn't stop at the desktop shell.
You'll also need to verify the underlying i18n infrastructure: IBus input method servers, Pango text shaping, system-wide font fallbacks, and locale-aware formatting for dates, numbers, and sorting rules. The Fedora I18N project's stated vision is to make technology "accessible and attractive for users of every language," and this test day is the practical check against that goal.
Known issues are already being tracked. Bug 2508253, for instance, flags a case where Workstation Russian webui installs don't include the layout switch config in /etc/X11/xorg.conf.d/00-keyboard.conf. If you're testing Russian locales, that one's already on the radar. Keep an eye on the Fedora 45 Beta blocker list and Final blocker list to avoid filing duplicates.
How to jump in
You can run the tests on bare metal or inside KVM, VirtualBox, or QEMU. Just make sure you're on a fully updated Fedora 45 build. If you're doing a fresh install, grab the latest nightly image from openqa.fedoraproject.org/nightlies.
Results need to be submitted in a specific format so developers can triage them properly. You'll need to log:
- Which variant? (Workstation, Silverblue, Kinoite, etc.)
- Bare metal or VM?
- Which language used?
- Which architecture?
- Upgrade or fresh install?
A profile might look like Silverblue, KVM, ja_JP, x86_64, Fresh. Submit your results here.
Bug reports are where the real value comes in. Commenting on the results page isn't enough. Developers need reproducible steps, screenshots, journalctl -b output, and terminal logs. The organizers emphasize exploratory testing: go beyond the checklist and hunt for the edge cases that only surface when you actually use your system the way you use it at home.
Who's watching
The i18n team will be online throughout the test day to answer questions and triage bugs. Look for Akira TAGOH, the veteran behind fontconfig and Pango work; Parag Nemade, active in Indic language support; and Twinkle Pardeshi from QA. You can find them chatting in the #i8n channel on Matrix at chat.fedoraproject.org.
Fedora 45 is currently in the freeze-and-polish phase. That means new features are locked down, and only critical bugs and i18n regressions are getting accepted. This test day falls right in the window where a well-timed bug report can actually get fixed before release. Miss this window, and broken text rendering or missing input methods could ship as "known issues."
For those looking to stick around after the test day, the i18n mailing list and the Fonts SIG are good places to dig into font packaging and text rendering work.
