As a new user of Lubuntu I am posting something here that worked well for me and may be of use to others.
My problem: Upon installation of Lubuntu (v. 20.04.2) the window backrounds are white; this is hard on the eyes to look at for extended periods, so I wanted to make my screen predominantly dark in color.
The solution I found is based on information from this article: 20.04 Contribution: Manual to customize LXQt and different color schemes for Breeze
Essentially what I am doing here excerpting the part of that article that gave me the quick fix I wanted.
Change the Breeze Color Scheme
- Copy the Breeze Dark color scheme, which is this file:
- Put it into `/home/your-user/.config/’ with the name kdeglobals
- Restart your computer
Upon restart, the dark color scheme should be working. If not, you might want to check that Application Menu >> Preferences >> LXQt settings >> Appearance >> Widget Style >> Qt Style is set to ‘Breeze’. Mine already was, so I did not have to do this.
If you want to play around more, I think you can modify the color settings in your new file kdeglobals by hand.
