Can not change the wallpaper – Xubuntu 18.04

I use Xubuntu 18.04 on my personal laptop, but I can not change the screen background. I did it before by right-clicking on the desktop and modifying desktop properties.

Right now, the right click does not work anymore (nothing happens when I open the system settings, I can see all the options but not "Desktop." Even when I open "Appearance", no tab concerns the modification of the bottom of screen.

I am wondering if I have modified or uninstalled a module related to the desktop configuration.

Clues?

18.04 – How can I have a single image spread on both monitors for wallpaper?

I looked at askUbuntu but there are only old answers to this question that I can find.

I have a wide image designed for two monitors. I am on Ubuntu 18.04. I choose the bottom of the screen and he displayed it twice, once on each monitor.

How can I extend it on both monitors?

Thank you

super-resolution – how to create a very high resolution photo for wallpaper

I'm building a house right now.

North of the house there is a forest.

I wanted to create a very high resolution photo of the forest to create a screen background (carpet? What is the correct English word, large scale printing to stick to the wall). I do not have a window on the north side.

It would be more than 10 meters wide, so I would need a high resolution.

I do not want a panorama with visible distortion.

In addition, as the forest is quite close (see photo attached from the roof, cropping a panorama, in winter, I would take the picture in summer).

What would be the appropriate method to create such an image?
Focus Stacking + Image Stacking to create a super-resolution solution?
Would I take pictures of several fists parallel to the edge of the forest to counter the distortions?

Available material:
Sony a6000
Sony a7 (friends)
different high quality lenses with different focal lengths
Gigapan Epic Pro Automated Panorama Head

Thank you
Daniel

How to change the wallpaper of Windows 10 with C ++?

I am trying to change the desktop background of Windows in C ++ using the Windows API.

I have read the following articles on this topic:

Problem:

When I run the code, the desktop background becomes completely black, as in the message above (yes, I've tried the suggested fix in this message. No luck.)

Code:

#understand 

int main () {
std :: string s = "C: \ picture.jpg";
SystemParametersInfo (SPI_SETDESKWALLPAPER, 0, (PVOID *) s.c_str (), SPIF_SENDCHANGE);
returns 0;
}

I've also tried just (empty*) instead of (PVOID *) above and one The in front of the string. Nothing works until now.

Is there a fix to prevent the edited text from being blurred in the wallpaper?

I have modified the text into an image in Paint 3D under Windows 10 and I have saved it in png format. When I set it as the desktop background, the option is set in the "span" settings. But the text seems blurry, but the picture is fine. I've cropped the section of the image that appears and has also changed its resolution, but the text is still blurry.
