Aegisub-wxQt

Aegisub with the wxWidgets/Qt 6 backend for Linux

build 9889-wxQt-29fd2d8cc, x86_64

What is Aegisub-wxQt?

Aegisub is a subtitle editor for timing and typesetting text over video, best known for the Advanced SubStation Alpha (ASS/SSA) format. The official build still uses a legacy interface toolkit that struggles with modern dark/light themes on Linux.

Aegisub-wxQt is a fork that moves the interface to Qt 6 (the wxQt backend of wxWidgets) so the application follows the desktop theme and runs natively on modern desktops, while everything from regular Aegisub stays intact: timing, typesetting, Lua automation, spectrogram audio, FFMS2 video.

wxQt backend fixes are maintained on branch wxQt of the forks ufalsalman/Aegisub-wxQt and ufalsalman/wxWidgets.

Minimum requirements

glibc 2.35 or newer (built on an Ubuntu 22.04 baseline).
DEB/RPM/pacman: Qt 6 installed from the system. wxQt 3.3, FFmpeg/FFMS2, libass, and other heavy libraries are bundled in the package.
AppImage: only glibc, the GPU driver, X11/Wayland, and the system audio stack come from the host.
DEB/RPM/pacman launch through X11/xcb by default (aegisub is not native-Wayland-ready); set QT_QPA_PLATFORM=wayland to override.
Hunspell spelling dictionaries come from the system (/usr/share/hunspell).

Installing

On a normal desktop install the package manager resolves everything by itself (verified on Fedora 43 and Ubuntu 22.04). Use the package manager, not the low-level installer, so dependencies get pulled in:

DEB: sudo apt install ./aegisub-wxqt_9889_amd64.deb — apt fetches the Qt 6 packages automatically. If you already used dpkg and it complained about dependencies, run sudo apt -f install.
RPM: sudo dnf install ./aegisub-wxqt-9889.wxqt.x86_64.rpm — dnf resolves the required libraries from the repos. On openSUSE: zypper in ./aegisub-wxqt-9889.wxqt.x86_64.rpm.
pacman: pacman -U does not fetch dependencies from the repos. On a minimal install, first run sudo pacman -S --needed qt6-base (harmless if it is already present, which is the case on KDE), then sudo pacman -U aegisub-wxqt-9889-x86_64.pkg.tar.zst.
