But many options in `xrdb -query` is setting that color, and this is the reason. And that's exactly some KDE-theming-TK-apps thing. I tried to install Kubuntu 10.04, and in gnome-boxes it could not configure the network. Luckily 18.04 has the same big list of options in `xrdb -query` and I was able to reproduce the issue. I traced source of the problem: > *background: #d6d2d0 But if you change this, many backgrounds change color. Now we need to find right *something*background to set that panel colors. I'll continue search tomorrow. -- Regards, Serg Tereshchenko
