On Lubuntu 18.04, I found the following commands will cancel each other
$ setxkbmap -option keypad:pointerkeys
$ xmodmap ~/.Xmodmap
I would like to be able to fully control my cursor using keyboard, with the first command.
I would like to remap left alt key to the super key, with the second command.
I wonder why they cancel each other? Can I get them both work? Thanks.
