When connecting to ThinLinc, users may be presented with a blue and white splash screen instead of a desktop session:
The underlying cause of this is poor support for running multiple desktop sessions as the same user, on most modern Linux distributions. See:
Why does starting multiple ThinLinc sessions as the same user sometimes fail?
If you encounter this problem, make sure you are not already logged in to the server as the same user as you are connecting to ThinLinc with. Often this means logging out at the server console (i.e. the physical monitor connected to the ThinLinc server itself).
This issue is currently being tracked as 8401 – Sessions often fail to start if logged in locally.
