    @Bharathi What exactly did you change and what exactly did not work? That file is only writeable by user root. You either need to start your app as root, or (THIS IS BAD!) you give others write access. You could for example define a group, give that group write access to that file and add your user to the group.

  • I want to change the screen orientation,so I add display_rotate=3 in config file.But the animation used in text is not smooth as I used in display_rotate=0.
