 ==== Installing x410 ====
+<WRAP center round tip 60%>
+[[https://token2shell.com/x410/|x410]] is a **low cost** commercial //X server// that can be directly installed from the [[https://www.microsoft.com/store/productId/9NLP712ZMN9Q|Microsoft store]].
+This is an //X server//, and you will get the same functionalities as what is already provided for free by [[other:x_conf#installing_vcxsrv|VcXsrv]], **but**:
+  * Once installed, ''x410'' will be automatically updated by the Microsoft Store application
+  * If you move to another computer, you can install ''x410'' again by just [[other:win10config#connecting_to_the_microsoft_store|Connecting the MS Store to your account]] on the new computer. No need to buy it again
+  * There seem to be more (useful) updates than for ''VcXsrv''
+  * The interface is more modern, with more options, and there is a lot of useful information on the web site
+  * The ''x410'' name is easier to remember! :-D

-Available at [[https://mobaxterm.mobatek.net/|MobaXterm]], not tested. This seems to be more than just an X server, and may be an overkill if you just need an X server

-  * Check if the ''DISPLAY'' variable is defined
+The idea is to:
-    * You should get something similar to the following if you are connected with ''ssh -X'' or ''ssh -Y''\\ <code>$ echo $DISPLAY
+  * Open a terminal and check that the ''DISPLAY'' environment variable is correctly defined on the local machine
-localhost:68.0

+==== On a Linux computer ====

+That's unfortunate, but:
+  * Have you turned on your computer?
+  * Do you have network access, and an account on a remote server?
+  * Have you run the [[other:x_conf#testing|Tests]]?
+  * Have you installed and configured the //X server// correctly? Is it really running?
+  * Have you configured [[other:putty_conf|PuTTY]] and/or other required applications correctly ?
+  * Is the ''DISPLAY'' variable defined correctly on the local and remote computer?
