I have installed nautilus! Thank you.
I thought I lost it altogether, not seeing what you were explaining.
So now I have a folder gtk-3.0 with a file named gtk.css.
I cannot copy paste the code because my mail is not on the phone.
I have to write it out in the terminal.
Does it need to be written stepwise as shown in the examples?
I just tried to enter the text straight into gtk.css, it is possible.
Aside: You can solve that by enabling the SSH server on your phone and SSHing in from the computer that does have your email (or anything else). Then you can cut and paste from email (or anything else) into a terminal session on your phone.
My phone is still not connected, I am still learning how to install the tunnel. Only after that I will turn my phone into my daily driver.
Thank you for your input.
To be clear … I only meant: SSH access from the local network, assuming that another computer on your local network is the one that receives email etc.
The first 3 lines are greyed out.
Are they part of the text to be inserted in the gtk.css
Thank you so much.
Thank you 
Everything between /* and */ is a comment. Its for people to read and isn’t code run by anything.
Thank you so much, it means I can leave it out?
If you want, yes.
You can leave it out, but comments are there to be referred to in the future, in case you, or someone you share the code with, need a reminder about what the script or specific lines of code accomplish. Personally, I would keep it just for that reason. Commented lines like those are basically present in every script.
Here’s a tutorial for setting up SSH (Secure Shell): https://source.puri.sm/Librem5/community-wiki/-/wikis/Tips%20&%20Tricks#secure-shell-ssh
Set that up and you will be able to log in to the L5’s terminal securely from your computer’s terminal over your home network. Then you can run commands or copy/paste text easily.
Also see the tutorial for sftp (to easily access the L5’s files directly from the computer’s file navigator), and the tutorial for Enhancing Security for Secure Shell (to replace password-based SSH login with encryption-key-based login).
You are the best!
Thank you
I think you mean nemo, right?
Having tried to install the “black mode”, not successfully! Is it possible that the earlier install of the dark mode is interfering?
Just a thought, before trying for the fourth time.
Thank you!
In short, please take a path that is kindly recommended here: [MyL5] Received my Librem 5 (Evergreen). And in addition, this already mentioned comment is probably (I didn’t check on this while not enough time) related to it (that wasn’t clear to myself right away):
Thank you Quarnero,
After writing this question in the forum, I decided to let it be in the meantime and live with the dark mode as is. Thank you for your response and help in the matter.
I am finally at the point that my phone is up and running, a lot because of your kindness to help and explain. For that I am grateful!
But back to the black dark mode! I have a question that I need an answer for to be able to understand how the gtk.css is activated?
the command: “sudo system restart phosh”, does just that. Restarts the system.
The gtk.css is in it’s folder gtk-3.0 under the main folder .config. Which command reads the script and activated what is written?
Thank you very much, have a good weekend.
“sudo systemctl restart phosh” will restart just the Phone Shell (Phosh) - the graphical interface - not the operating system.
It (phosh) should then re-read the gtk.ss file.
Thank you so much.
The gtk.css is activated automatically, just by nature of its being located in the gtk-3.0 directory, which is itself located within the .config (i.e. system configurations) directory. In other words, Phone Shell (phosh) “consults” it, if you will, when it starts to run. (CSS for Firefox, for example, does a similar thing, by consulting a CSS file within the Firefox profile/directory. That’s how users can change appearance of tabs, colors, behavior, etc., in Firefox, if the Preferences/Settings interface doesn’t cover it.)
As a point of clarification, the gtk script I pointed you to does not activate any kind of dark mode, such as dark themes, dark icons, etc. It simply loads any custom background that you have designated for your app grid and the “launch” image (the image you see after you start an app, before the app fully loads).
It just so happens that your chosen background image is a simple black image (I think), so it’s understandable that you might call it “black/dark mode,” but that’s not what the script is actually doing.
You are not a teacher, are you?
Now I finally understand why I don’t see a difference.
Thank you for explaining the workings.
