Yesterday I turned off my laptop(normal usage... without any new package installation), and after I turned on my laptop my menu bar's icon are messed like below: which gone icons are for bluetooth and keyboard layout(language).
I really don't know why should this happen. because at the time this happened I am 100% sure that I didn't do anything out of normal usage(just playing music and programming) to cause this.
Question
How can i fix this annoying icons?!
Thanks in advance.
