I use Gnome 3.16 under archlinux and would like to know if there is a quick way to change the integrated monitor with an external one via HDMI. This is the way I have to go (in pictures):
First, you have to open the monitor menu (here in spanish).
Second, you need to open the submenu (where you can choose out of four options: Make this monitor the primary, secondary, show the same content, or turn it off) of your external monitor and choose the option to show the same content in both monitors.
Third, you need to open the submenu of your integrated monitor and turn it off.
Does someone know an easier and faster way to do it, i.e., that as soon as you plug in the HDMI cable it automatically switches to the external monitor while turning off the integrated monitor and vice versa?
This is scriptable with xrandr. You can use the friendlier arandr to generate scripts that call xrandr. Run arandr twice, once for each config you wish to keep. Do a “Save As” to save the two xrandr scripts. Then you simply call the appropriate script whenever you want to switch monitors/configs. I name my scripts like xr1 and xr2 and have a hot-key menu (as part of window manager) to quickly invoke them (or any other script).

I need to create a simple Delphi application, kiosk style.
It is a very simple thing, a single form where the user writes some personal info to register to an event. 4 TEdit and a TButton.
What I want to achieve is to avoid the user does any action different then typing in TEdit or clicking on the TButton. For example I don't want he does ALT TAB (switchin applications), pressing windows key on keyboard, doing ctrl-alt-canc, etc...
I can add a passowrd protected Button that enables/disables this "Kiosk mode", in this way as I need to exit the kiosk mode I simply press that button and exit.
How to achieve this "kiosk mode" in Delphi without intercepting all the keystrokes manually? Or did anyone already develop this so it can be shared?
I think you'd better create a new desktop, and run your app in there. When your app is done, you can bring back user's desktop. That is how Windows login screen works. Of course Windows login screen uses a special secure desktop. Your app in a separate desktop would be isolated. You will have a desktop background with no start menu, taskbar, or desktop icons because explorer.exe is not running there automatically. Of course a can start a new process, using Task Manager, but desktops in Windows are securable objects; therefore, you can make restrictions if you want. Of course if your app has sufficient permissions.
To create a new desktop, you can use CreateDesktop Windows API, and to switch to the newly created desktop, you can use OpenDesktop function.
You can try Change the Windows Shell.
When you start windows, you don't execute the default shell (explorer.exe), you can execute your application.
Al internet you can find alternative Shell (more attractive) to default windows like:
BlueBox or
SharpE
This option is used for purposes similars at the application that you are developing. Kiosks or TPV.
For change the default applicacion you must modify a registry key:
In Win3.x and Win9x, SYSTEM.INI file:
[boot]
shell=MiAplicacion.exe
In Win2k and WinXP, use Registry:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
Shell=MiAplicacion.exe
If you test this option, think the mode to turn the configuration to the original value (button or option). You must reboot to test changes.
ADDED: In addition, if you search on the web some similar at this "Delphi Change default windows shell", you can find more code, samples and information about this.

P.D: Excuse me for mistakes with english.
Well but if someone can open the taskmgr he could just create a new task and run explorer.exe from there so its not really secure though...
Ok Taskmgr can be stopped with policies...
Well and for disabling the cad sequence you can use saslibex which Remko Weijnen had created you can find it here: SASLibEx
kindest regrads,

I have this program that I've written in PyCharm. This program should be running for a week or so, and it is very processor-needy. So when I run it I pretty much have no use of my notebook, as it becomes very laggy.
Is there a way to somehow tell PyCharm to use first three of my cores and leave one for other programms so they can operate normally?
Go into task manager
Find the running task (it probably won't be the main pycharm window)
Right click and select "go to details"
Right click on the details and click "set affinity"
Select whatever cores you wish the program to use
Alternatively you can use the "set priority" sub-menu and set it to "below normal". All other processes are normal priority by default, so it shouldn't interfere with anything, but still use any other available processing power. You can do the same thing with long installations or automatic windows updates so they don't slow you down.
I should also note that both of these selections will be reset upon restarting the program. Additionally, if you are using windows 7, you don't need to "go to details". Everything will appear in the context menu for the process.
Unfortunately, I don't know how to do this in pycharm.
Requirements:
Our application replaces the usual windows shell (explorer.exe). This is a product requirement for a closed system that we're supplying.
We oughtta let the user select a wi-fi network and connect to it.
The problem: The wi-fi networks dialog only shows up when explorer.exe is running
What we tried:
Write our own wi-fi manager that uses wlan API. It lists connectible networks and allows the user to connect/disconnect. Problem: too many network types/configuratons that have to be tested, especially when the wheel has already been invented and reinvented all over.
Try and check how is the networks dialog implemented. It appears that it's and undocumented COM interface (IUIRAdioManager). Problem: it's undocumented, so no API
Use an existing network manager, for instance the one that comes with the driver. Problems: it's ugly, not to the product's taste; and it opens too many options for the user, like creating and loading profiles, browsing for files on a file system - these things are unacceptable.
Running explorer.exe just for the purpose of showing the networks dialog and then killing it. Problem: once we run explorer.exe - it pops up metro view and hides our fullscreen application or shows the taskbar.
The latter seems like the preferred solution: no need to reinvent the wheel, it does what's needed. Just gotta make explorer.exe not pop out, keep it quiet in the background.
So, we're down to two options:
How to show the networks flyout dialog without explorer.exe?
How to run explorer.exe without it popping out metro or taskbar above our application?
Your first solution would be incredibly difficult to implement. I am almost certain that the Networks window is dependent on explorer.
However, your second is entirely possible.
To hide the taskbar, you will need to find a window (using FindWindowEx) to find the taskbar (name is Shell_traywnd). This will hide the taskbar and start button. EDIT: Unless you are implementing your own taskbar, you might want to set the taskbar to autohide.
Next you will need to hide all of the metro programs. In a similar fashion as above, find the class named EdgeUiInputWndClass and close it. You should be able to get the process name of it and then kill the process.
Windows key. This is a little more difficult. You will probably need to use a program and delete the key or a keyboard hook (a low level keyboard hook) and just ignore key presses with the same scancode as the windows key. Left Windows is 0x5b and Right is 0x5c (source). Note that this will not block Ctrl+Alt+Del.
Finally, to show the Flyout, you can run %windir%\explorer.exe shell:::{38A98528-6CBF-4CA9-8DC0-B1E1D10F7B1B}
(source).
EDIT2:
You should also be able to hide toast notifications via this
Of course, I don't see why you cannot just use Windows 8/8.1 and put the app in kiosk mode.
I am missing some of (perhaps all) system tasks that used to be available in context menus of the previous Windows versions. Please see the attached image for details.
Is there a way to make, say, "Move" easily available (so that I can, e.g., move a window from invisible part of display within a remote session)? How?
Use shift + right click (eightforums.com)
I am considering writing a graphical tool that will show you what gnu-screen sessions you have and what windows are available in them. You would then be able to, for example, click on the window title and it would take you there. I do not want to modify gnu-screen in any way so that my tool can work with existing installations on other machines and so on.
I can get ordinary output from programs running inside screen out of the screen session by using a log-file, or by copying the last few lines into the exchange-buffer. What I really need in order to make a nice user interface though is the contents of the status line (the line that temporarily appears at the bottom of the window). For example, to get the list of windows in a session I can send the windowlist command, but the result is never part of the output. Does anyone know if there is a way to make screen put its messages into the log, into a paste-buffer, into the current window, or anything similar where I can grab it from another program?
