I'm writing a presentation software. I control the presentation on my primary screen, and I display it on the second screen. If the image on the second screen doesn't change after a while, my computer turns off the second screen. Off course, I could simply disable powersaving features on my computer, but what I'd like would be to have my software tell the OS not to turn off the second display when it displays fullscreen on it. How can I achieve that? I'm on Linux, and using Python and GTK3.

I would like to show an image with transparent background to indicate something when a key combination is pressed.
Let's say I pressed ctrl+f3, I trigger a python script. Is there anyway I can make that happen?
What python library can I use to show an image without window border and background?
I have figured out how to trigger the file on key press. How to I deal with the (imshow) thing?
Thank you.
show an image without window border and background
This sound like task for some GUI library. There are many available but you would need test them in order to find which one can do it. First feature is generally known as frameless or borderless window. tkinter which ships with python has ability to work this way, see for example tutorialspoint.com tutorial, though I do not know how it will work with alpha channel of your image.
I created a PyGTK application which needs to be always on top. The transparent window redirects mouse clicks to the window below and therefore gets out of focus once you click into an underlaying window. This is the intended behaviour. In fact it should just show a little image that's always above everything.
This works well unless you use something like the libreoffice fullscreen presentation. The presentation window is marked as always on top as well and hence my window goes into the background. Even if I take it to front using Alt+Tab and then click onto the underlaying libreoffice slide (which is neccessary) my window goes into the background again.
This is a really specific question and the solution should work on both Linux and Windows. I have no idea what I should do. I just found many questions on how to have a windows always on top but none of them covering my problem.
Long story short: How can I put my window always on top of every window that is always on top as well?
Simple Answer: You can use 'Always on Top' in windows with by using AutoHotKey scripts.
Follow these steps:
Install AutoHotKey
Create a new AHK scripts following the images
Add this code ^SPACE:: Winset, Alwaysontop, , A
Next, double-click your script to run it. You’ll know it’s running
because a green “H” logo appears in your system tray to let you know
it’s running as a background process.
Now press Ctrl+Space to set any currently active window to be always
on top. Press Ctrl+Space again set the window to no longer be always
on top.
In raspberry pi using Python is there any way to make a program where according to the place you click on a designed screen actions can be taken and output given accordingly.
I am using the raspbian-jessie os and have a 7 inch touch screen, I want to create buttons on the screen. When I click on a button it should execute a program.
you probably put the wrong tag, there is nothing to do with functional-programming or graphics, and still little relations with whether you are in raspberry pi or something else
you mean you are in linux and got a touch screen, and want to add some indicator on your touch? what desktop are your using, or something to do with the hardware.?
please state your question clear! and don't let me guess your expection
Look into Kivy or Qt. These are the most popular GUI interfaces for Python.
I am a developer with low vision. Right now I am working on a personal project to improve my ability to make use of large screens and play video games.
Sometimes when using a widescreen monitor up close (within 4-8 inches) I have trouble reading the screen along the edges. This is particularly troublesome when trying to read the clock or use a mini map in a game. It would be nice if I could temporarily switch the edge of the screen with the center.
I have successfully been able to move parts of the screen using screen captures and PyQt (screenshot).
This is nice but I would like to do this while preserving my ability to click or select text in the region. This seems like a rather involved process If I want to use PyQt and somehow pass clicks through to the screen.
For example:
Is there a lower level api that would allow me to tinker with the screen's output? Any suggestions are welcome!
Thanks
I want to take a print screen of a particular window on my PC by running the python program and it taking that screen shot, before cropping it and comparing its hex value to other hex values in a SQL server.
I have thought about letting it wait 10 seconds whilst I get the other window up and then start taking the print screens continuously until one matches.
I was just wondering if I can use python to maximize that particular window that I want to print screen automatically and then have it take a print screen.
If not, could I take a print screen (a picture) of a window that is minimized? (I think this is impossible)..
Thanks!
If you do a quick Google search, you will find this helpful tutorial that uses PIL to take a screenshot of a desktop:

Assuming you're on Windows, you would need to use PyWin32 (or possibly pywinauto) to get the window you want. These two links will help with that:
Get HWND of each Window Python

Then you could use MoveWindow to resize the window you found before taking the screenshot:
