ThinLinc remote session windows are appearing on the local desktop, making them unusable

Hi @zhanghongtao,

Thank you for your post!

The problems you are experiencing are very likely related to the same root cause as discussed in this post:

Why does starting multiple ThinLinc sessions as the same user sometimes fail?

One feature of ThinLinc is the ability to start and manage multiple sessions as the same user. When logging in with the native client, if you already have one or more existing sessions on the server, then you have the option of reconnecting to an existing session, or starting a new one. As an administrator, you have the ability to restrict your users to a maximum number of concurrent sessions. If ThinLinc is installed in a cluster configuration, a user with multiple sessions may find that each …

In short, the vast majority of modern desktop environments assume that only a single graphical session is running per user. Assuming you are logging into ThinLinc and the local machine using the same Linux user, this is the cause of your problems.

The easiest way to circumvent this is logging in to ThinLinc using a different user than you used to log in locally to the machine.
