This problem seems to occur once every day or so, and can be temporarily fixed with a restart. When opening an application from the launcher, the icon will pulse for a while with no error, when opening from the terminal, an error similar to "Unable to open display" will be returned.

Applications affected:

Geany
System Settings
Rhythmbox
Libre Office
Google Chrome
xkill
Wine
Gedit
Many more


Applications not affected:

Files
Ubuntu Software Centre
KAlarm
Many more
