This occurs when trying to start the unity8 greeter under unity system compositor |
[Impact]
LightDM reports the system compositor socket to Mir clients using the MIR_SOCKET variable. This stopped working in Mir 0.21. The Mir team says the correct variable is MIR_SERVER_HOST_SOCKET and MIR_SOCKET was a fallback to that.
[Test Case]
1. Start LightDM with a Mir greeter
Expected result:
Greeter starts
Observed result:
Mir greeter fails to start. It is attempting to access the video drivers directly (i.e. not through a compositor).
[Regression Potential]
Risk of using LightDM with older version of Mir that doesn't support MIR_SERVER_HOST_SOCKET. Risk of behaviour change in Mir using MIR_SERVER_HOST_SOCKET.
