I want to start an application (a clock) in x windows and I want to
-- not be focusable
-- not be cyclable
-- not be in window list
-- not be in task list
-- not have a visible frame
In other words, I want only to attach the clock on the desktop and this is all.
It is possible to do this from window menu toggling these parameters but I want to start it from command line, to be able to do it instantaneously.
For those things the application dose not do them, as some of the comments say. The application does set hints as to what it wants. The window manager, window list etc, will do what ever their policy is: ignore, honour, or a bit of both.
In kde/plasma you can tell set a configuration that does all of this, based on application, and/or window title, and/or some other properties.
Edit: I have just discovered devilspie and a gui configurer for it (gdevilspie). They can do the same as KDE but for what ever Window manager you are running. Should be able to solve your problems. Other X11 control tools are xdotool, and wmctrl.

I am a noob when it comes to Desktop GUIs. Is there a way for me to programmitically figure out which application window is the top most in terms of display environment?
So, basically, I can have a process running in the background, that might then change the behavior of the top-most (or say the selected) window. My go to operating system would be MacOS (then Linux family). Also, for instance, there is an app called spectacle app, which listens to key bindings to snap resize and move active windows on MacOS.
I've currently connected two monitors via a dock to my notebook.
When I'm running my console application, the console window always pops up on the first monitor. How can I change that it's automatically opened on another monitor, e.g. on monitor 3? Maybe there is a property I need to modify?
It's very annoying to always drag the console window onto the monitor on which my IDE is opened.
Console applications (unlike GUI applications) don't create their own window; that's done by Windows, and in the case when you're running in an already created console, then you kinda inherit, e.g., cmd's window.
What you can do, though, is to find your window and move it to a different monitor.
Another option is to change the window manager settings for that application in the properties of the console window under Layout. Especially the check box »Let system position window«. To do so, first move the window where you'd like it to appear, then open the properties, go to the Layout tab, and just click »OK«.
I'd like to show another app's windows under my app's taskbar button. It's a background app that reports another process's windows as my app's own. Is there any universal way to do this, e.g. each "new" window, alert glow, progressmeter, and other taskbar features, show under my own app's button?
For example, Winfox runs under its own process and steals Firefox's windows. It also adds features, but that's irrelevant -- I just want to support another app's existing taskbar features under my own app's button -- multiple windows, progressmeter, alert flashing, error flashing, mini-icons, etc. Is there a near-universal way to steal an app, or is it largely app-specific? Thanks!
You should be able to use SetParent() to take ownership of a window, but I'm not sure how much this will help you in your attempt to add taskbar features to the legacy app.
We have a Linux based system that does not use a Window manager. When we start certain applications (for instance Firefox) from a terminal window (e.g. Firefox &) we find that no matter what we do, we can't get the application to display full screen.
If we run xrandr, it shows the default resolution is 1280x1024, but when we try to maximize Firefox (by pressing F11) the application is only sized to 1203x650.
Another application that seems to have the same problem is the evince PDF reader.
Our application is not configured to run a window manager (and we don't want to add one), so I'm wondering if there is something else that we can do to get these applications to render full screen.
Thanks...
Although you don't want to use a window manager, you might need to use a window manager.
I haven't dug into the X server sources around this, so I can't definitively say X requires a window manager to run properly. But as somebody who writes X client code, and hacks the X server, on minimalist embedded devices with small screens, low CPU power and no GPU... let's just say, all the major players in that space use one, and have good reasons for it.
If you want to avoid chewing up a lot of disk space, RAM or CPU power doing window management, you should check out matchbox. It's a low-footprint window manager designed to meet those criteria, and it's what many folks in that minimalist embedded space are using. My employer uses it on cell phones, configured so that only one app at a time is visible to the user, and the foreground app takes up the whole screen with no window borders. But you can use it other ways, too - Nokia uses it for their Maemo-based network tablets.
You could use xwit(1) to forcibly resize and place the windows. But as as far as I know, X11 in itself does not have the concept of a "maximized" window; the very idea is only added by most window managers and/or applications (like Firefox).
Does passing the "-geometry=1280x1024+0+0" option to Firefox help?
Oh, also... if you don't explicitly set a window manager, you might be unexpectedly falling back to the default X11 window manager. If you're not absolutely positive there's no window manager, you should check into this possibility.
I have a few different things open in the terminal whenever I'm developing -- log tailing, Ruby console, plain shell in a certain directory, and so on.
How do I:
start all those things at once, hopefully in the right position on the screen?
make them distinct so I can switch to them with Quicksilver / Alt-Tab?
Fluid solved this problem with all of my web apps, so now I want to do it with my terminals.
And while we're on the topic, has anyone found a working solution for getting OS X to remember window positions on an external monitor? If I unplug it and plug it back in, I have to drag everything back to the same position (although at least Mercury Mover makes it possible to do it with the keyboard.)
Open Terminal, and go into Preferences, then go into the settings tab, and create a new setting for each of your windows that you want. Either give them all different colour schemes, or duplicate a colour scheme multiple times for them all to have the same settings. Under the shell sub-tab, add "Run command" to be run at shell startup. (This is the command that will cd to the directory you want, or tail a log).
Then initialise the windows as you want. Then click Window in the main menu and select Save Windows as Group...
In OSX Yosemite you can use (in Terminal) Window -> Save group. It will do all the work for you.
