As you’re probably aware Ubuntu 16.10 was released yesterday and brings with it the Unity 8 desktop session as a preview of what’s being worked on right now and a reflection of the current state of play.
You might have already logged in and kicked the proverbial tyres. If not I would urge you to do so. Please take the time to install a couple of apps as laid out here:
The main driver for getting Unity 8 in to 16.10 was the chance to get it in the hands of users so we can get feedback and bug reports. If you find something doesn’t work, please, log a bug. We don’t monitor every forum or comments section on the web so the absolute best way to provide your feedback to people who can act on it is a bug report with clear steps on how to reproduce the issue (in the case of crashes) or an explanation of why you think a particular behaviour is wrong. This is how you get things changed or fixed.
You can contribute to Ubuntu by simply playing with it.

Unity 7 has had a low graphics mode for a long time but recently we’ve been making it better.
Eleni has been making improvements to reduce the amount of visual effects that are seen while running in low graphics mode. At a high level this includes things like:
- Reducing the amount of animation in elements such as the window switcher, launcher and menus (in some cases down to zero)
- Removing blur and fade in/out
- Reducing shadows
The result of these changes will be beneficial to people running Ubuntu in a virtual machine (where hardware 3D acceleration is not available) and for remote-control of desktops with VNC, RDP etc.
Low graphics mode should enable itself when it detects certain GL features are not available (e.g. in a virtualised environment) but there are times when you might want to force it on. Here’s how you can force low graphics mode on 16.04 LTS (Xenial) :
- nano ~/.config/upstart/lowgfx.conf
- Paste this into it:
start on starting unity7
initctl set-env -g UNITY_LOW_GFX_MODE=1
- Log out and back in
If you want to stop using low graphics comment out the initctl line by placing a ‘#’ at the start of the line.
This hack won’t work in 16.10 Yakkety because we’re moving to systemd for the user session. I’ll write up some instructions for 16.10 once it’s available.
Here’s a quick video of some of the effects in low graphics mode:
Scopes are a leading feature of the Ubuntu Phone and of Unity 8 in general. That concept, the story of scopes, started out in Unity 7 and in 12.10 when we added results from online searches to the dash home screen.
Well, we’re making some changes to the Unity 7 Dash searches in 16.04 LTS. On Unity 8 the Scopes concept has evolved into something which gives the user finer control over what is searched and provides more targeted results. This functionality cannot be added into Unity 7 and so we’ve taken the decision to gracefully retire some aspects of the Unity 7 online search features.
What is changing?
First of all online search will be off by default. This means that out-of-the-box none of your search terms will leave your computer. You can toggle this back on through the Security & Privacy option in System Settings. Additionally, if you do toggle this back on then results from Amazon & Skimlinks will remain off by default. You can toggle them back on if you wish. Further, the following scopes will be retired from the default install and moved to the Universe repository for 16.04 LTS onwards:
The Music Store will be removed completely for 16.04 LTS onwards.
By making these changes now we can better manage our development priorities, servers, network bandwidth etc throughout the LTS period. We allow ourselves more freedom to make changes without further affecting the LTS release (e.g SRUs), specifically we can better manage the eventual transition to Unity 8 and not have to maintain two sets of scope infrastructure for the duration of the LTS support period of five years.
What about previous supported releases?
Search results being off by default will not affect previous releases or upgrades, only new installs (i.e. we will not touch your existing settings). Changes to search results from Amazon & Skimlinks will also only affect 16.04 and beyond. The removal of the Music Store will be SRU’d back to older supported releases and the option will be removed from the Dash.
When will this happen?
We’re preparing the make the changes in the archive, to Unity 7 and to the Online Search servers right now. This will take a little while to test and roll out. We’ll let you know once all the changes are in Xenial.
