What is new in Ubuntu desktop 17.10
- 32-bit installer images are no longer provided for Ubuntu Desktop.
- The Ubuntu Desktop now uses GNOME instead of Unity.
- On supported systems, Wayland is now the default display server. The older display server is still available: just choose Ubuntu on Xorg from the cog on the log in screen.
- GDM has replaced LightDM as the default display manager. The login screen now uses virtual terminal 1 instead of virtual terminal 7.
- Window control buttons are back on the right for the first time since 2010.
- Apps provided by GNOME have been updated to 3.26. For more details about GNOME 3.26.
- Driverless printing support is now available for IPP Everywhere, Apple AirPrint, Wi-Fi Direct, and Mopria devices. Follow the instructions from 17.04.
- Printer configuration is now done in the Settings app: Choose Devices and then Printers. The tool uses the same algorithms for identifying printers and choosing drivers as the formerly used system-config-printer, and makes full use of driverless printing to support as many printers as possible. Note that some options, like printer sharing, are missing. To reach them, click the Additional Printer Settings… button at the end of the list of available print queues and you get good old system-config-printer.
- The Amazon app now loads in the default web browser.
- The default on screen keyboard is GNOME's Caribou instead of Onboard.
- Calendar now supports recurring events.
- LibreOffice has been updated to 5.4.
- Python 2 is no longer installed by default. Python 3 has been updated to 3.6.
- The Rhythmbox music player now uses the alternate user interface created by Ubuntu Budgie developer David Mohamed.
- The Settings app has been redesigned.
- Simple Scan has a new workflow and design and is now part of core GNOME.
- System Log has been replaced by Logs, an app to view logs from the systemd journal.
- The Ubuntu GNOME flavor has been discontinued. If you are using Ubuntu GNOME, you will be upgraded to Ubuntu. Choose the Ubuntu session from the cog on the login screen if you would like the default Ubuntu experience.
- Install gnome-session and choose GNOME from the cog on the login screen if you would like to try a more upstream version of GNOME. If you'd like to also install more core apps, install the vanilla-gnome-desktop metapackage.
