I was once playing with Emacs settings through SSH from Raspberry to another PC. I hit F10 and checked Options > Blink Cursor. The cursor started blinking. I unchecked it and it did not stop blinking, also
M-x blink-cursor-mode only prints
Blink-Cursor mode enabled or
disabled not changing anything.
A very strange thing is that Emacs cursor continues blinking even when out of SSH on my Raspberry. The second PC is untouched. Did it mess up something with my TTY config? I want it back to be static. Reboot did not help. When out of Emacs everything is in place.
EDIT: Everything works fine in desktop terminal (e.g. xterm), but framebuffer TTYs blink cursor in Emacs.
