Ubuntu 17.10

Ubuntu 17.10 Artful Aardvark will be released soon today. Here’s how you can upgrade from the Ubuntu 17.04 desktop.

Ubuntu 17.10 replaces Unity with Gnome Shell as its default desktop environment. It’s powered by 4.13 Kernel and runs Gnome on Wayland by default. Xorg is also available for choice.

A fresh install of Ubuntu 17.10 is recommended. But for those who want to upgrade from Ubuntu 17.04, do:

1. First is always backup your important data, bookmarks, and other user documents.

2. Launch Software & Updates utility from application launcher,

  • in first tab, choose “Download from” Main server
  • in Other Software tab, remove/disable all third-party repositories.
  • in Additional Drivers tab, choose an open-source driver if a proprietary one is in use.

3. Remove other desktop environments (KDE, Cinnamon, etc). Upgrading desktop packages may take a few more minutes in the upgrading process.

4. Make you system up-to-date by running command in terminal (Ctrl+Alt+T):

sudo apt update && sudo apt upgrade

5. Finally launch Software Updater to get the upgrade option. Or run following command (-d is required before it’s officially announced):

sudo update-manager -d

Click the Upgrade button and confirm in the next release note dialog to start the upgrading wizard.

Note: while the upgrading process, you need a few clicks to confirm installing or removing some packages.

gnome shell

Boring with the default purple login screen background in Ubuntu 17.10? Well, here’s how to make a change by hacking the css file.

Ubuntu 17.10 switches to Gnome 3 Desktop and GDM display manager. Although there are options to change desktop wallpaper and lock screen background (it’s actually screen saver with date & time displayed), the login screen is always purple.

GDM login background

In the picture above, I’ve changed the login background to the image “Aardvark_Wallpaper_Grey_4096x2304.png” locate in /usr/share/backgrounds.

1. Move your favorite image to /usr/share/backgrounds:

It’s better to move the image you want to set as login background to system pictures folder: /usr/share/backgrounds.

To do so, open terminal via Ctrl+Alt+T, then either run command:

sudo cp PATH/TO/YOUR/IMAGE /usr/share/backgrounds/

or run command to open file browser via root and then do copy and paste in that window:

xhost +local: && sudo nautilus /usr/share/backgrounds/

2. Edit the css file that define GDM login background:

Open terminal (Ctrl+Alt+T) and run command to edit file /etc/alternatives/gdm3.css, which is linked to /usr/share/gnome-shell/theme/gdm3.css:

xhost +local: && sudo gedit /etc/alternatives/gdm3.css

Input your password (no visual feedback while typing) when it prompts and hit Enter. And of course back up the file before editing.

3. When the file opens, go to menu (right after ‘Save’ button) -> find and find out following section:

#lockDialogGroup {
  background: #2c001e url(resource:///org/gnome/shell/theme/noise-texture.png);
  background-repeat: repeat; }

change the lines into:

#lockDialogGroup {
  background: #2c001e url(file:///usr/share/backgrounds/Aardvark_Wallpaper_Grey_4096x2304.png);
  background-repeat: no-repeat;
  background-size: cover;
  background-position: center; }

Replace Aardvark_Wallpaper_Grey_4096x2304.png with your picture file name.

Finally save the file and restart your computer to apply changes.

NOTE: these changes may be overwritten in case of an system update with GDM packages. Please let me know if you find a good way to change the GDM3 login background in Ubuntu 17.10.

gnome shell

Tested Ubuntu 17.10 beta 2 recently and that the touchpad ‘Tap to click’ feature does not work in my laptop while I’m in the GDM login screen, even though it starts working once logged in.

If you get the same problem and want to re-enable the ‘Tap to click’ feature in login screen before Canonical adding it back, following steps will tell you how.

You can enable ‘Tap to click’ either in Settings utility or via gsettings command. For working in the login screen, you need to do it under the gdm user.

1. Open terminal via Ctrl+Alt+T, then run command to get root privilege:

sudo -i

Type in your password (no visual feedback while typing) when it prompts and hit Enter.

2. (Not required in default Wayland session) Allow user gmd to create a connection to the X server:

xhost +SI:localuser:gdm

3. Switch to user gdm in the terminal:

su gdm -s /bin/bash

4. Finally enable ‘Tap to click’ via gdm user:

gsettings set org.gnome.desktop.peripherals.touchpad tap-to-click true

Restart your computer and done.

How to Restore:

To restore the setting, open terminal and re-do previous steps except running following command instead the last one:

gsettings set org.gnome.desktop.peripherals.touchpad tap-to-click false
