I have read this article & I added
se gcr+=a:blinkon0 in my vimrc to stop blinking cursor in my Vim, also I sourced my vimrc again but the matter is it doesn't work & cursor is still blinking in all modes. Please let me know why it doesn't work for me & How can I fix it?
OS: Fedora Linux 27 x86_64 & Vim version: 8.0
Edit 2: I think I have found a solution for that. Actually Herb Wolfe was right and this option seems not working on Vim (but in gvim it works fine). For stop cursor blinking you can disable cursor blinking in your terminal emulator instead. Also this wiki may help.
