An X-Client Wrapper for Microsoft Windows?

S asks: "In my opinion, one of X11's most underrated features is the ability to export the display of an [X] application to an X-Server that can be physically separated from the application's host (use a remote display). I have used this countless times to dramatically increase my ability to 'get stuff done' from a distance. Recently I discovered Cygwin's ability to run XFree86 in rootless mode (startx -- -rootless) where there is no main X root window, and imported displays get their own 'native-looking' window on the Microsoft Windows platform. This also has saved me much headache when working from a Windows machine to do Linux-type things. My question is: Is there some way to export the display of Microsoft Windows windows to a remote X-Server? I'm not talking VNC/RFB here, and terminal services (via rdesktop) ALMOST fits the bill, but I don't want a root window. I want to simply export the display of (say... photoshop) to my X workstation. Googling is not an easy task; 'windows' is too much of a generic term to get usable results. What I have found, however, suggests Wine as a buffer between native Windows GUI calls and the X protocol, but offers no actual solution. Does anyone know of software that allows allows Windows to export the display of its windows to an X server (ie, an X-Client wrapper for Windows)?"

My comment isn't really helpful, but I wanted to chip in with a clarification. Rootless mode is not a feature of Cygwin, but XFree86 itself. It is of primary use for MacOS X users who want to run X apps [locally or not]. It is also useful for running a second X server on top of another, though the applications of that are particular.

Tightvnc: desktop sharing

[jeorgen]

If you want to get a window on Linux with one single Windows application in it, the screen sharing application tightvnc has a beta (se bottom of page) where you can e.g. share just one window instead of the whole screen. they've named it partial desktop sharing

Not yet possible, but XOpenWin wants to be this

[khanyisa]

No, there are no real X-Clients for Windows currently - I wrote that message you linked to. Like others have suggested, you can use either VNC or RFB to accomplish similar ends.

There would be amazing advantages to doing it differently though - for more discussion on this see XOpenWin

although nothing has yet been accomplished through this project. The key things to do which would make this possible are:

• separate out the Wine GDI and x11drv dlls (see this message)
• port these dlls to cygwin
• persuade windows to use them in place of the normal gdi

If anyone is really interested in that solution, it will take time and effort, but is definitely possible. Join the mailing lists!

Slight restatement

[Masem]

In Cygwin's XFree: "-rootless" gets you windows without any window decorations at all unless you start an X window manager as well in the session, which gives you X type decorations while in Windows. Of late (since start of 2003?), Cygwin now supports "-multiwindow" which is like rootless, but give control of the window decorations and handling to the Windows OS, thus making such windows appear no different from the other apps you have up.

My only nits about either modes is that you still have a root X window (standard grey crosshatch) that's started minimized but otherwise sits in the process list and can sometimes make quick switching a bit more difficult without activating the wrong X app. I'd wish that the Cygwin X server could be started as a background service such that 1) it stays off the process list, and 2) to get an xterm to a remote computer up, I would simply have to ssh to that computer via putty or cygwin's ssh, point DISPLAY back , and let loose the X applications, as opposed to having to start the X server on Windows manually each time.

You don't have to set DISPLAY when you use ssh.
Just use "ssh -X -C remotemachine".
The -X flag will handle setting DISPLAY for you.
The -C compression flag is optional,
but usually speeds up remote X apps.

Re:Citrix

[scrybe_treo]

To expand on this, Citrix Metaframe runs on a windows 2000 Application Terminal Server. This adds a lot of manageability and the ICA protocol. You can access applications in "seemless" mode with the modern unix clients. While it is extremely cool and works very well it's not a solution for a single user but more for a department or enterprise level. This is mostly due to cost. Something like 2000+ dollars for the product, 300+ dollars for each connection licence, and 85 bucks for every pre-windows2000 client. Given the potential benefits it is well worth the price if you can avoid having 2 pc's on each desk.

Disclamer: I am a CCEA and CCI working for a citrix implementer (http://www.vector.com) but it is a blast!!!

Alkit VNC

[richardneish]

I know you specifically said "not VNC/RFB", but Alkit VNC may do what you want. It is a modified version of WinVNC that allows you to share a single window instead of the entire desktop.

I don't know what relationship (if any) it has to the modified version of TightVNC mentioned in another thread, but I've used it and it works.
