Canonical has released Ubuntu 25.10 Questing Quokka. There are a couple of important changes in this release.
Ubuntu 25.10 comes with the GNOME 49 desktop environment, making Wayland session the only option available for users. It does not support X11/Xorg sessions. Ubuntu 25.10 ships with Linux kernel 6.17, based on 6.17-RC7. It includes Mesa 25.2.3 drivers with support for Intel Core Ultra Xe3 integrated Intel Arc graphics, and Intel Arc Pro B50 and B60 “Battlemage” discrete GPUs.
The proprietary Nvidia driver now supports Suspend-resume by default, in order to reduct freezes and corruption when waking up from sleep. Fractional scaling has been improved to reduce blur. Ubuntu's default monospace font size has been reduced to match the UI font size in terminals and similar apps.
The update changes some default apps. Ptyxis terminal emulator is now the default terminal, replacing the GNOME Terminal. Loupe image viewer replaces the Eye of GNOME as the default image viewer. Ubuntu now uses sudo-rs, which is a new Rust implementation of the sudo tool. The initramfs-tool has been replaced by Dracut, which uses sytemd, for the default initial ramdisk infrastructure. It supports new features such as Bluetooth and NVM Express over Fabrics (NVMe-oF). Chrony is the new default time-daemon in Ubuntu 25.10, replacing systemd-timesyncd, and uses the Ubuntu Network Time Security (NTS) servers by default. Apps can be set to auto-start at boot from the Settings > Apps.

Ubuntu's Software Updater window will not pop up or steal the keyboard focus, when system updates are available. The OS will display a notification, that has options to open the Software Updater or to install all updates directly.
An icon in the system tray reminds you that updates are available even after dismissing the notification. It also provides a quick way to apply all the updates or inspect them in the Software Updater. Ubuntu 25.10 brings experimental support for TPM-backed Full Disk Encryption (FDE), for added security.
