I know that the default theme of oh-my-zsh already is not great, but with white background it really get's shitty. This is something to look later

[fititnt]

Hummmmmm.... interesting. One way to change the background colors of the terminal is go to Terminal > Edit > Preferences > Profile > Colors and disable "Use colors from the system theme".

Maybe this alone could be somewhat acceptable instead of use the full zsh. But for now I will just do the bare minimum and keep going. Anyway is documented here on this issue for everyone search later at least know some cosmetic changes

Terminal > Edit > Preferences > Profile > Colors

Default ( Terminal Options + screen with default oh-my-zsh theme)

Removing "Use colors from system theme" ( Terminal Options + screen with default oh-my-zsh theme)

[fititnt]

humm... ok. Now one problem is how to persist the terminal profiles. This does not seems to be saved betwen sessions.

[fititnt]

Ok. The terminal options seems to not be saved some type of filesystem file, but can be accessed via dconf command.

If is this, even if Tails do not support "save" betwen sessions, would be possible to run some startup script that would do the trick.

amnesia@amnesia:~$ dconf dump /org/gnome/terminal/
[legacy/profiles:/:b1dcc9dd-5262-4d8d-a863-c897e6d979b9]
use-theme-colors=false
visible-name='custom-profile-theme'

[fititnt]

While not fully well documented, since this is just an MVP, I think we could close.

About the change on the terminal background, see Persistance of cosmetic changes on TailsOS terminal #9.
