I am trying to setup Unity on a ubuntu server 14.04 the installation itself didn't give me any errors but i can't run Unity with "/opt/Unity/Editor/Unity -quit -batchmode -nographics -silent-crashes -serial mySerial". First i got the following error: Aborted This application failed to start because it could not find or load the Qt platform plugin "xcb". Available platform plugins are: xcb. Reinstalling the application may fix this problem. I was able to fix this by installing the xcb package with "apt-get install xcb" but now I get the following error: Aborted QXcbConnection: Could not connect to display I think this is odd because http://docs.unity3d.com/Manual/CommandLineArguments.html states that the "-nographics" option prevents Unity from initializing any graphics devices. I would love to get this working so i can setup a continuous integration on my ubuntu server. Thanks in advance for any help/feedback.
