On one of my devices I need double pressing
C-g to quit from a minibuffer, even when no initialization file is loaded.
More specifically, after pressing
C-x C-f, if I do not realease the control botton, I only need one
C-g to quit the minibuffer. But if I realease, I need two.
If I only press
C-g once, the minibuffer shows the text quit, but the cursor is still focused on the minibufer, and I have to press
C-g again within 3 seconds, otherwise the Find-File minibuffer reappears after the text quit fades in 3 seconds. And in that case, I will need to double-press again to quit.
GNU Emacs 24.5.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.20.6) of 2016-06-04 on juergen
I solved this by switching off the option of
Show position of pointer when the Control key is pressed in Linux mouse setting.
I guess there is some conflict between Emacs and this option.
