I am using genome terminal in Ubuntu 16.04 (just in case!)
I set my colorscheme to atomdark and I have atomdark.vim in both my ~/.vim/colors and /usr/share/vim/vim74/colors.
I set this in my .vimrc file
set t_Co=256
syntax enable
colorscheme atomdark
but when ever I start vim its o a different colorscheme and if I save the vimrc file by :w the atom dark color scheme will be set but every time I start vim I should do the saving .
If I don't, it will be on the default colorscheme every vim start.
Note: Tried the scriptnames and tracked down some paths but I could not understand a word of it. If it is the case I need specific help for it.
