how can i divide a RHEL 6 screen into many parts each one displays different thing like DVR; because I've to monitor many clients remotely through vncviewer so i want to display this multiple sessions on a large LED TV monitor thanks in advance

What Desktop are you using ?

KDE

is kde's windowmanager capable of tiling?
or, it's also possible to integrate a tiling wm into kde. or change altogether away fro kde.
if those are terminal apps, you can also use a terminal multiplexer like tmux or screen.
or a tiled terminal like terminator.

sorry, but i have to ask this: you are aware that you have loads of virtual desktops to use?

the apps are gui
i know that there are many virtual desktops but i want to show all the windows in the same desktop each one in separate part of the screen like the DVR

You can't do this natively, but there IS a script for the latest Plasma 5:

That said, there's a few things that are confusing about your post:

• You're using RHEL 6..paying for it? Ask their support? RHEL isn't typically used for desktop environments to start with, and 6 is old.
• You're monitoring clients..with VNC Sessions?? Why?? You can SSH with X forwarding, and have the application(s) come up in windows on your location workstation easily, and tile them all you want by resizing the windows. Doing it with VNC is not only slow, but insecure.
• If you are monitoring many clients/nodes...why can't you use a real monitoring application, like Nagios/Zabbix, etc., which will let them all be monitored on a single screen?
• KDE by default supports multiple desktops/workspaces. Tiling separate screens is only going to make them tiny and illegible, and won't be usable for much. And since you're monitoring 'manually', the refresh rate isn't good...you WILL drift your eyes, go to the restroom, etc. So using a screen-edge desktop switch would be just as easy, and actually let you see what you're looking at.

...and you followed up with...
..which goes right back to "Why can't you use SSH with X forwarding???"

I had a large screen and found tiling wm is lot cool. Check out this if you are interested in tiling window manager https://awesomewm.org/

I didn't find RH softwate to do this job.
Because i monitor some users actions, and doesn't bring the current view from the remote client ( if there is away i'll be so grateful to you if you show it to me )
i tried to use them but i can't install them because they need fresh installed linux version with minimal applications but in my case i have many application installed because i need it.

And the question was: "Are you PAYING FOR RHEL, and did you contact RHEL Support??"
If you're spying on user activity, there are far better ways to log what folks are doing than watching a tiny piece of a screen.
Wrong, they can be installed on any system easily, and this tells me that you didn't even look at the documentation for either of them. Nagios is even in the Red Hat repositories...which you can install by typing in "yum install nagios-server-addons". Which will work easily if you're paying for RHEL. Otherwise, you can install from source easily too.

it's for my company and they pay for it.
and i didn't even think to contact RH support because i thought they are not concerned with that(maybe i'm wrong)

i dont spy any one and i don't need.
i didn't let the installed packages to allow them to do any thing but work
and they work with some application and i need to do this for some complicated reasons i thing it doesn't worth to mention any on them here
i didn't know before that vnc is made for spying
we work offline
i'll try more
thank you

You're wrong. The paid-for support should be the FIRST thing you use. They are a global company with many partners...telling them what you need may get you what you're looking for, if not from them, from another partner.
..and you said: "Because i monitor some users actions". What, exactly, are you monitoring where you need to see exactly what's on their screen then???
Asking a clear question with clear goals is the only way you're going to get any good answers. Saying "its complicated" tells us nothing.
...which is what you're using it for, obviously, since you said you're using it to monitor your users "current view from the remote", right????

we've some application running on all the clients which they work on it.
some actions they may not know haw to do or do it wrong and they may want to show it to me.
maybe sometimes i've to perform some operations myself on the clients side, and i think will not let me do it as it should be because it should be running on the clients side
by the way im 2KM away from them in another building

...and none of this is what you said initially, is it??? It's gone from "monitor user actions" to now being a tech-support role. Which is it???

Want to do tech-support? Then you're obviously not going to need multiple screens at once, are you? Can't work on multiple users at the same time with one keyboard/mouse, can you? So using a single VNC viewer is fine. And if something breaks, then 2KM isn't that far, and (since you're doing support), it's your job to fix it anyway.

If you have to perform "some operations", then ssh will work just fine. You are NOT CLEARLY STATING what you're trying to accomplish, and keep changing the story. You were handed a link to something that lets your WM doing tiling, and told to contact RHEL support...did you do either?

thank you
