Talk:X Window System protocols and architecture

Urgently needed for this article
X Window System was at 30KB and it was clear the technical section would need at least 15KB to do it justice, and was also of notably lower quality than the rest of the article. So I split it off. - David Gerard 13:13, 26 Jan 2005 (UTC)

Things this article needs (add to this list):


 * Extensions (only a few are currently mentioned)

I have added some technical details, but there are some points missing: for example, a discussion about screens and visuals. In the examples, I made some simplifying assumptions (for example, in the the example section I have assumed a single screen; when talking about selections, I have assumed that the client is requesting a text selection, etc.) This may be misleading, but explaining everything in the level of details of the specifications is too much.

keyboard input with XKB
It needs some information on how the keyboard input in X works. At the web I found   The X Keyboard Extension: Protocol Speci&#64257;cation. --Hhielscher 01:10, 3 Feb 2005 (UTC)


 * Keyboard handling is now in X Window core protocol, and in X keyboard extension. - Liberatore(T) 15:05, 24 January 2006 (UTC)

Split (again)
This article has reached 33k... I propose to split the sections:


 * X protocol
 * X services
 * Objects
 * Example
 * Xlib

into a new article X Window core protocol, leaving a summary here. The section "Inter-client communication" is also quite long, but I think it can be left in place. Comments? - Liberatore(T) 20:46, 19 December 2005 (UTC)

Done. I have removed some things from the list of the things that are missing as they should go to X Window core protocol instead (a new list is in the talk page of that article). - Liberatore(T) 19:01, 27 December 2005 (UTC)

Peer review of a related article
I submitted X Window core protocol for peer review, as I intend to candidate it for featured status. I would appreciate comments (Peer review subpage). - Liberatore(T) 17:55, 21 February 2006 (UTC)

XRandR
Could somebody knowledgable about X Windows take a look at the article XRandR. It is important? Should it be merged somewhere? deleted? Not sure myself but it seems fairly out of context and of questionable importance by itself... Jefferson Anderson 20:49, 5 February 2007 (UTC)

Vandalism?
"Ken Sanders X-pert on the X protocol" under Obsolete Extensions was added on May 6 by an anonymous edit.

"and sends back user input..."?
The following paragraph doesn't make sense to me:

X is based on a client-server model. An X server program runs on a computer with a graphical display and communicates with various client programs. The server accepts requests for graphical output (windows) and sends back user input (keyboard, mouse).

Why would the server send back user input?

 * I grant that sentence could be made clearer. The point is that the server is between the user and the client program. It receives keypresses from the user and send them to the program. I will try to clarify this. Thanks for pointing this out. Tizio 13:35, 10 November 2008 (UTC)
 * Ok, I have changed that sentence. I think it is clear now, but suspect it could be improved as for the language... Tizio 13:42, 10 November 2008 (UTC)

So how do you use the protocol?
If I develop an app to display in an XWindow, what kind of protocol is it? Is it a network protocol that works with normal UDP or TCP packets? Does it use shared files or memory locations, so that communication is file-mapped or memory-mapped? Please explain.
