Fix blurry wallpaper bug when starting with multiple monitors in Ubuntu

About the blurry wallpaper bug

Several people have told us that when starting their Ubuntu with multiple monitors you always start them with blurred wallpaper on some of the monitors, apparently a fairly common problem that can go unnoticed, but for the most demanding users, here is the solution.

This solution has been tested on Ubuntu 16 with two monitors, one HDMI and the other VGA with DVI adapter, the HDMI monitor always started with blurry screen background and inappropriate dimension. It is a shell script that will take care of properly sizing the wallpapers, according to the resolution of your monitor.blurred-screen-background-on-multiple-monitors

Script installation

Si tienes instalado unzip, solo debes copiar y pegar en el terminal y ejecutar:

wget -O uwf https://git.io/vPQ4f && chmod + x uwf && ./wwf && rm uwf

Si no tienes instalado unzip, puedes hacerlo con el siguiente comando, luego ejecuta el anterior

sudo apt-get install unzip

The script will automatically correct the problem in question.

How to uninstall the script

If you want to uninstall the script to correct the bug, just run the following command:

wget -O uwf -rm https://git.io/vPQRL && chmod + x uwf-rm && ./uwf-rm && rm uwf-rm

    Hello, I have two problems with my Ubuntu 14 LTS, I have my main monitor with FullHD 1920 × 1080 resolution connected to the graphics card via DVI and via VGA to a FullHD 1920 × 1080 television that is in another room.

    If I turn on the computer while the TV is on, the image is perfectly cloned both on the TV and on the monitor, and the screensaver looks clear.

    But if I turn on the computer with the TV turned off, which is usually the most common, then I have this problem that is mentioned about the blurry screensaver, and also that the TV detects it as CRT at 1024 × 720 resolution and not cloned, so I have I always have to modify the NVIDIA driver to change the resolution of the tv and put 1920 × 1080 and clone the output.

    No matter how much I save this configuration in the xorg.conf file, the same thing always happens to me.

    I have tested the script in this post, and the part about the screensaver being blurred has been fixed, thank you very much.

    Any idea what I can do so that it always starts with the same resolution (1920 × 1080) on both screens and the cloned image?
