How to set environment variables for the calibre program (to get dark theme) in Mint Cinnamon [solved]

[pepperminty]

I'd like to change the theme of Calibre and the developer has made his program quite customizable: https://manual.calibre-ebook.com/customize.html#id1 . According to that link, we can use "CALIBRE_USE_SYSTEM_THEME".

My question is: How do we set this environment variable on Linux Mint Cinnamon?

Thanks!

How do we set this environment variable on Linux Mint Cinnamon?

In the same what as on Linux Mint xfce, Linux Mint Mate and even on Ubuntu.

some minter helped me with this:

env CALIBRE_USE_DARK_PALETTE=1 calibre .

i then just modified the command line in the calibre shortcut i dragged from my mint menu to the panel

[karlchen]

In analogy, the variable CALIBRE_USE_SYSTEM_THEME could be set in the same way:
env CALIBRE_USE_SYSTEM_THEME=1 calibre
Really, the online help could be a bit more specific on how to set the (optional) environment variables on Linux systems.

karichen,
initially, i tried env CALIBRE_USE_SYSTEM_THEME=1 calibre but it did nothing. i then tried env CALIBRE_USE_DARK_PALETTE=1 calibre and it worked. the developer said he didn't give instructions for linux because there's multiple answers (because there's multiple linux flavors)

you put the wrong one. you should put in this:

env CALIBRE_USE_DARK_PALETTE=1 calibre

No case, change the command and reboot the system and nothing

[pepperminty]

could you try opening a Terminal and running the same command

env CALIBRE_USE_DARK_PALETTE=1 calibre

Yes now, thank you !! I am happy
