Ubuntu 25.10 Questing Quokka is coming soon, and it’s one of the most exciting short-term releases in years. Packed with radical changes like Rust-based sudo, a new default terminal, TPM-backed full-disk encryption, and a Wayland-only session, Ubuntu is pushing its desktop experience further than ever before.

In this video, we take a detailed look at every major new feature in Ubuntu 25.10, from behind-the-scenes system updates to fresh visual tweaks.

🆕 What’s New in Ubuntu 25.10?

🔒 TPM-Backed Full-Disk Encryption
Ubuntu 25.10 refines the experimental TPM (Trusted Platform Module) encryption introduced in 25.04. You now get:
• TPM-only mode: Your system unlocks automatically at boot — no typing required.
• TPM + Passphrase: Adds an extra security layer requiring your password each time.
• Recovery Key: If you forget or miss the passphrase prompt, you can use a recovery key — saved to an external drive or via a QR code.
Older machines can still use LUKS-based encryption or even skip encryption entirely.

💻 Ptyxis Terminal – The New Default
GNOME Terminal is out, and Ptyxis (GTK4-based) is in.
• Container Integration: Directly hop into Podman, Toolbox, or Distrobox containers.
• Terminal Inspector: Debug your running processes with a GUI-style inspector.
• Themes & Modern UI: Multiple color schemes and a polished GTK4 interface.
Note: Docker isn’t supported out of the box — a big miss for many users.

🖼️ Loupe Image Viewer
The default image viewer is now Loupe, replacing Eye of GNOME.
• Touch & Gesture Support for touchscreen devices
• Supports 15+ image formats including PNG, JPEG, WebP, and SVG
• Detailed metadata display and sandboxed image decoding for security

🦀 Rust-Based sudo (sudo-rs)
The classic sudo has been rewritten in Rust as sudo-rs.
• Memory-safe and less prone to vulnerabilities
• Works like old sudo for most users
• Some advanced sysadmin features like Sendmail integration, LDAP configs, and wildcard specs are gone
• You can still use sudo-ws for now, but by Ubuntu 26.10 the old sudo will be removed

🖥️ Wayland-Only Session
Ubuntu 25.10 removes X11 completely.
• No session switcher at login — Wayland is now the only option
• Better security and smoother performance moving forward

🎵 GNOME 49 Features
• Toggle app autostart directly from Settings → Applications
• Lock screen media controls to pause or skip without unlocking

🎨 Visual & System Tweaks
• New wallpapers, refreshed icons, and sound theme
• Ubuntu Insights replaces Ubuntu Report for cleaner, consent-based system metrics collection

⚙️ Under-the-Hood
• Linux Kernel 6.17 for better hardware support (including Snapdragon X Elite laptops)
• Short-term support release — supported for 9 months. LTS users should wait for Ubuntu 26.04 for long-term stability.
