I am posting this message from my Fibre os.
I know many people may want their Fibre Os to look like this:
Thankfully it is possible and this is how:
Firstly, follow these instructions here:
https://bitcointalksearch.org/topic/m.8909808 to give your OS more capacity.
(you'll probably need at least 8gb)
Then once you have done that, press Ctrl+Alt+F2 to open a Terminal in fullscreen.
Type "fibre" (all lower-case and without the ") for the username and
"Fibreos" for the Password (with a capital F and without the ")
Then you will have logged in successfully.
Now, to install the new GUI you will need to type:
sudo apt-get install ubuntu-desktop
followed by the Enter key.
If will ask you for the Password. Type "Fibreos" and press Enter.
Now your computer will install the new GUI.
If you don't want to install extra programs such as libreoffice (they take up a bit of space) then instead of typing the command above, type:
sudo apt-get install --no-install-recommends ubuntu-desktop
Near the end of the installation a message will come up with two options. One will be "gdm" and one will be "Lightdm"
Select "Lightdm" with the arrow keys and press Enter.
After everything has finished installing, type "exit" into the Terminal. This will log you out of the terminal.
Now you can press Ctrl+Alt+F7 to go back to the desktop. Restart your computer now.
When Fibre OS boots back up you will be presented with a boot menu allowing you to select which disk you want to boot. (GRUB 2)
To boot from your usb, find the line that says Ubuntu and press enter. This will boot the os again.
If you want to get rid of this slightly annoying menu, log into Fibre OS and press Ctrl+Alt+T to open Terminal.
Now we are going to install a program called GRUB Customizer. This program will allow us to stop the boot menu from appearing.
Copy and Paste (or type) these lines into the Terminal: (make sure to only paste (or type) one line at a time otherwise it doesn't work)
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer
Now your computer has a new program called GRUB customiser.
Now search for it by pressing the button in the top left corner of the screen and typing "GRUB customizer"
click on the icon to open the program. You will need to type the password to open the program. (its "Fibreos" without the " in case you forgot)
Now under the List Configuration Tab, hold down Shift and highlight all of the option except the first "Ubuntu" option.
Click Remove at the top and then click save.
Now click the "General Settings" tab.
Make sure the options "show menu" and "look for other operating systems" is unticked.
Click save again if you needed to untick any of those options and now you can close the program.
Now every time you boot from the USB it will boot directly into the FibreOS with the other boot options and it will have the new theme.
