  • There, set Alternate Background to be the same as Normal Background. Click Save. Use a new name for the theme to avoid altering the original Breeze Dark. Close the window. You'll be returned to the first Applications Color Scheme window. Click on the theme you just "created" and then click on Apply in the lower right corner. Close System Settings. Now when Dolphin is opened, there shouldn't be alternating colors for rows in detailed view. This works in Kubuntu 16.04.2 LTS with kubuntu-backports enabled (Plasma 5.8.7).

For quite a while I wanted to make the background of the file area in Dolphin Transparent or Translucent - like the Folder View Widget that I could have on my desktop.
Over the years I messed with different ideas and had a little success, but not the look I wanted to go with my translucent panels and window decorations.



This week I finally achieved a completely translucent 'Dolphin'.
The Bright Red buttons and selections will not be everybody's choise - but they can all be toned down. The 'Blur Effect' is enabled using GL3.1 in compositing settings in Kubuntu 18.10, but the translucency works and can be adjusted without the blurring using Xrender and in earlier versions of Kubuntu.



Dolphin against a coloured background



Dolphin against a black and white background to show how the blurring enables the white text to be seen



This was achieved very simply using the Kvantum theming engine and Kvantum Theme Manager. There's more info and images on my Linux, The Whitsundays and Me blog.



While this is not changing the background image in Dolphin, quite a few of us found this topic whilst trying to make a translucent background in Dolphin - so I hope this helps.

    This week I finally achieved a completely translucent 'Dolphin'.
    The Bright Red buttons and selections will not be everybody's choise - but they can all be toned down. The 'Blur Effect' is enabled using GL3.1 in compositing settings in Kubuntu 18.10, but the translucency works and can be adjusted without the blurring using Xrender and in earlier versions of Kubuntu.



    Dolphin against a coloured background



    Dolphin against a black and white background to show how the blurring enables the white text to be seen



    This was achieved very simply using the Kvantum theming engine and Kvantum Theme Manager. There's more info and images on my Linux, The Whitsundays and Me blog.



    While this is not changing the background image in Dolphin, quite a few of us found this topic whilst trying to make a translucent background in Dolphin - so I hope this helps.

      For quite a while I wanted to make the background of the file area in Dolphin Transparent or Translucent - like the Folder View Widget that I could have on my desktop.
      Over the years I messed with different ideas and had a little success, but not the look I wanted to go with my translucent panels and window decorations.
