Ubuntu – How to properly restart unity

14.04unity

I keep on experiencing weird bugs. These usually start after a few hours of use. Sometimes the dash starts opening under every open window (becomes only visible on desktop, but I still can search and open anything with the enter key while it's not visible). Also, there are other minor annoyances, such as random places (especially maximized Chrome, tabs area) after navigating between programs with alt+tab can't be clicked with the mouse. Switching back and forth fixes this.

I cannot use

compiz --replace

since after that, all of the app indicator icons are gone (only teamviewer stays). Skype, network, languages, sound (also keyboard sound up/down stops working) and date are gone. Restarting unity-panel-service does not help.

Any thoughts on how to resolve these?

You can press Alt+F2, then type unity, then press Enter to restart Unity.

Or you could use:
```
sudo service gdm restart
```
On 14.04 and 14.10 use:
```
sudo service lightdm restart
```
On 15.04 and 15.10 use:
```
sudo systemctl restart lightdm.service
```

I don't use Unity but given what I know of its mechanics, this should work:

unity

You'll want to stick that in a run box (Alt+F2) rather than a terminal or it'll break when you exit the terminal.

If you want to run it from a terminal use:

setsid unity

Ubuntu – How to restart Unity 2D

unity-2d has some of its own processes and some processes that derive from unity (unity-2d uses unity libraries).

You can find these processes with:

ps aux | grep unity

This yields these (see the right-most tokens in the above command output):

unity-2d-launcher
unity-2d-panel
/usr/lib/unity-place-applications/unity-applications-daemon
/usr/lib/unity-place-files/unity-files-daemon

Each of these can be individually stopped (and each will automatically restart) with:

sudo killall <process>

So to kill them all, list them all in the above command:

sudo killall unity-2d-launcher unity-2d-panel \
/usr/lib/unity-place-applications/unity-applications-daemon \
/usr/lib/unity-place-files/unity-files-daemon
