            How can I check a user's idle time in Linux?
            Asked 2021-May-25 at 04:20

            I have a cluster of virtual machines on cloud (Digital Oceans), and I want to find a way to turn them off if they are idle for at least 1 hour.

            I imagine it is similar to how a screensaver decides to kick in after an appointed duration of idle, or how some cloud services like Snowflake or Databricks can turn off resources if they are not used for a duration.

            I have checked the w command and do not find any info that can tell me idle time, although that command's output has an idle column.

            If you know how a screensaver kicks in, or how cloud services turn off resources, please share. Much appreciated.

            === UPDATE ===

            After running w | awk '{if (NR!=1) {print $1,$5 }}', my output is like this

            Audio keeps playing after screensaver ends
            Asked 2021-Apr-27 at 13:20

            I'm working on a screen saver with (optional) audio. But whenever i deactivate it by swiping the mouse, the audio keeps playing for a few more seconds. This does not happen when clicking preview in sys preferences though. My theory is that when moving the mouse in preview, the screensaver process gets instantly killed, but not when it's not running it as preview. Is there a way i can sense mouse activity and stop the audio myself by running a function? I have supplied some code below: https://gist.github.com/MaxTechnics/3d4280fabc4da53b6df1022864d1bf23 Will provide more if requested. Thanks in advance!

            Updated: this is what i think is the main part of the problem since the audio never stops in time

            After some fiddling, while we can't intercept keyboard (and shouldn't to reliably detect a quit), it's actually possible to listen to some distributed notifications in the screensaver that tells us when the user gets logged in, and use that to call our code to stop animations/sound, as there's a sizable lag between the moment we are effectively killed and the moment the user gets back to desktop.

            I did find some events in this answer here : Monitoring Screensaver Events in OSX and while it's a bit dated those events are still fired and can be intercepted inside the screensaver despite the sandboxing. I did found a few new ones though that may be interesting for other purposes.

            Anyway, here's what's working for me :

            Swing is event driven, this means that you never directly call painting methods. Basics for a custom painting component:

            • extends JComponent
            • override paintComponent(Graphics g), this is the point where you can put your rendering code
            • override getPreferredSize(), so that the layout managers can do their duty, a suitable value is your image size

            Is there a way to have a Java Swing application as a child of a native HWND window?
            Asked 2021-Mar-30 at 18:06

            I found this question that does the opposite: embed a HWND window inside a JPanel, but it's obviously not what I need

            According to Wikipedia a valid Windows screensaver supports the /p flag to spawn the screensaver as a child of the specified window (instead of fullscreen or whatever it does by default). This is used, for example, to render the preview in the screensaver selection tool.

            Side notes: I'm using Scala, so maybe there's some weird Scala API I can use. My main window is just a JFrame with

            NOTE: The code examples here will not compile and omits the error code checks, but is just to show your the order of Windows API calls needed to dock any Java Swing frame inside Windows native HWND parent - for your own implementation in JNI /JNA or JDK16+ Panama.

            Firstly work out parent Windows long hWndParent. For Windows Screensavers this is passed into the "SCR" executable as with "/C" or "/P" (upper/lower) plus parent HWND argument. It may have SPACE or ":" separating the flag and HWND, or as two arguments FLAG + HWND so make sure you parse long hWndParent handle from the number passed in to main(String[] args) as:

            Deactivate a ScreenSaver programmatically
            Asked 2021-Feb-15 at 22:06

            I have an ACEPC T6, with a 7 inch LCD screen connected via HDMI, and a USB touchscreen.
            This system is connected to a processor board via a USB serial link which reads various sensors and feeds the data back to the PC.
            The program on the PC is written with VB.NET 2019. Everything works fine with one exception.

            I use the ScreenSaver to blank the screen after 10 minutes of activity, and touching the screen brings things back fine.

            My problem is that I have a PIR sensor connected to the processor, which sends a command back to the PC. My objective is for this to simulate the screen being touched, and the display be restored, i.e. when someone walks into the room, the display returns.

            I have tried all sorts of options, simulating mouse effects, sending key strokes, but all to no avail.
            Any help would be appreciated.

            I should have mentioned I am running Windows 10 Pro.

            You're probably not able to have a positive result using SendInput() or other functions because a ScreenSaver runs in special Desktop, named (guess what) Screen-saver.
            You need to get the handle to this Desktop to actively interact with it or its Windows.

            You can use the SystemParametersInfo function, passing SPI_GETSCREENSAVERRUNNING to determine whether a ScreenSaver is currently active, then call OpenDesktop() get the handle of the Desktop (using its name), find the ScreenSaver Window (the ScreenSaver is a standard executable) and post a WM_CLOSE message to close it.

            Here, I'm using EnumDesktopWindows to find the ScreenSaver.
            (The ScreenSaver Window should the be Foreground Window anyway).
            In case it fails, we can try to close the Desktop, calling CloseDesktop().

            Some more possibly interesting info related to ScreenSaver here:
            Handling Screen Savers

            If you have a procedure that receives a Command through a serial port or something similar, verify whether this procedure is run in a Thread other than the UI Thread, in case you need to access the UI in this occasion.

            Add this code to the procedure: it checks whether a ScreenSaver is active and tries to close it.
            It's been tested in both Windows 10 (19H2) and Windows 7 SP1.

            NOTE: your app is meant to run as a 64bit process. If you have set Prefer 32-bit in your Project's Build option, you need to deselect it.

            ► Assuming this procedure is run in the UI Thread. Me.Activate() is not strictly required and can be used from the UI Tread only. Remove it if your code runs on a different Thread.
