OS: Debian
WM: Compiz
DE: Gnome
Wallpaper: All credits goes to BrainBurnerCo, who made this conky config (i adapted only some small things such as adding the time, removing the upgradable packages counter,...)
Term: Urxvt with neofetch, cmatrix and ranger
Other apps: Conky, Firefox, Spotify
I also made shortcuts thanks to a plugin from Compiz, such that (almost) all my shortcuts from i3 are present (to open custom rofi, terminal, Firefox,... adjust light/sound,...)
How what?
Big ass picture of Saturn can be found here (originally from NASA, it's on their site somewhere too).
The clock, computer stats, etc is Conky, which is basically the Linux equivalent to Rainmeter (from what I hear).
The music thing in the bottom left is a Rhythmbox plugin
The cube (and fishies therein) are all Compiz plugins.
> So Mac OSX Terminal handles ANSI color sequences and preserves transparency despite change in colors, gnome-terminal does not do this well and color changes through ANSI color sequences will mess up previous transparency settings. Is this right?
Yes. The Mac handles it better because OS X has built in window compositing stuff where gnome-terminal has to fake the transparency itself. In my gnome-terminal if you have a window underneath the terminal window the transparency shows the desktop background instead of the window in back. You might want to take a look at Compiz. If you are patient, it looks like Ubuntu is moving to Compiz + Wayland soon which should give it some of the same window compositing features as OS X.
> So can Emacs be modified to not send any background-changing commands at all?
I don't know the answer to that. I've never seen an option for it but I wouldn't completely rule it out.
