The error message in the log above means that the server hit input-stub.so while looking for graphics modules. It fails to load input-stub.so since it does not explicitly link to libmirclient.so which contains the given missing symbol. Additionally because qtmir is loaded as a plugin the input-stub.so cannot resolve that symbol through the already loaded libmirclient.so.
This warning message was fixed by adding the runtime dependency to stub-input.so. That fix will land with mir-0.14.0
Still this warning should not be related to any startup failure, since even due to the reported failure to probe stub-input the system picks a different graphics module. So something else is causing the failure.
