I am using orgmode and after I put my files under git I see some lines that appear next to lines that have changed. They are red, green or blue.
I would like to disable this but have no idea how they are called.
The highlighting is performed by
diff-hl-mode from the diff-hl package, and can be toggled with
M-x diff-hl-mode, or unconditionally disabled by passing a negative argument (
M-- M-x diff-hl-mode interactively,
(diff-hl-mode -1) from lisp) like most minor modes.
To find out yourself which minor mode is causing the effect you could use f1 m (
describe-mode) and look in the help buffer to see what minor modes are active, along with the major mode -- those will likely give you a clue as to what is causing the bitmap images to be displayed in the left fringe.
manage-minor-mode package could also be helpful to debug cases like these.
