Can the openSUSE installer expose screen-reader support before the graphical YaST frontend loads?

Direct Answer

Yes – current openSUSE Leap and Tumbleweed installation media can provide audible output before the graphical YaST frontend starts. The feature is enabled by adding kernel parameters at boot; there is no dedicated boot‑menu toggle that turns it on automatically.

How It Works

• The boot menu (GRUB2 or Syslinux) allows editing the kernel command line. Adding textmode forces the ncurses YaST installer, which runs in the console before any graphical environment is loaded.
• The initrd includes the speakup kernel module and the espeakup user‑space daemon. When the module is loaded and the daemon started, it can speak any text that appears on the kernel console.
• Combining the two options gives a working console screen reader during the installer’s text interface.

Recommended Kernel Parameters

textmode speakup.synth=soft

textmode forces the ncurses YaST UI. speakup.synth=soft loads the software synthesizer (espeak) via the speakup module. In practice this combination produces audible prompts from the installer’s screens.

Verification Steps

1. Boot the openSUSE ISO in a VM or on hardware.
2. At the boot menu, press F4 (or E on some builds) to edit the kernel parameters.
3. Append textmode speakup.synth=soft to the existing line and press Enter to boot.
4. Listen for spoken prompts from the ncurses YaST installer.
5. For comparison, repeat the test without speakup.synth=soft; no speech should occur.
6. Optional: inside the initrd, run lsinitrd | grep espeakup to verify that the daemon is present.

Limitations & Uncertainty

• Minimal or very old net‑install images may omit espeakup from the initrd, leaving the module loaded but no speech output.
• Only text rendered to the kernel console is spoken. Complex YaST widgets that rely on graphical drawing may not be fully accessible in text mode.
• Behavior is confirmed for Leap 15.5+ and recent Tumbleweed snapshots; earlier releases may differ.

Early Accessibility Toggle Feasibility

The installer architecture does not preclude an early accessibility toggle. Adding a menu entry that injects textmode speakup.synth=soft would be a straightforward packaging change. The speakup module loads early in the kernel, and espeakup starts from the initrd’s systemd units, so speech is available by the time YaST’s ncurses frontend initializes.

Missing Diagnostic Detail

Which specific ISO image (Leap version, Tumbleweed snapshot date, full DVD vs. net‑install) are you testing? The presence of espeakup in the initrd varies by image type and age, and that single fact changes whether the parameter combination will work out of the box.
