I looked up several answers on StackExchange network, neither of them worked as I wanted.
I started using
urxvt on Ubuntu instead of
gnome-terminal, and wanted to configure it's look to be similar. I succeed with fonts, but can't beat transparent background. What I want is mix 60% background and 40% Ubuntu Mid aubergine (
#5E2750) -- that's how my
gnome-terminal was configured. I tried several combinations of values for
Urxvt*background (tried with alpha channel too),
Urxvt*fading (doesn't look actually useful here, but most examples I met set that too) and
.Xresources. Every one was not even close, most of them gave completely black background. Looks like I am wrong at understanding
background settings, but documentation is not so rich about them.
