[PATCH] matrix-gui: Clear background when starting and stopping matrix.

[PATCH] matrix-gui: Clear background when starting and stopping matrix.

[Jacob Stiffler]

* Clearing the background is done by calling refresh_screen with the
  "background-black" argument.
* Always switch virtual terminals so that command prompt will be visible
  upon exiting matrix.
* Disable blinking cursor while matrix is running, re-enable when stopping
  matrix.
    - When using qt over eglfs, the blinking cursor will show through the
      gui.

Re: [PATCH] matrix-gui: Clear background when starting and stopping matrix.

[Cooper Jr., Franklin]

Overall by modifying this init script your making changes that are only needed for Qt 5 eglfs users. Users can use Qt 4 and Qt 5 Wayland which this patch may cause problems for.

Honestly your probably better off duplicating this init script and making a Qt 5 eglfs variant since there seems to be a significant amount of tweaks. Then select which init you want based on if Qt 5 is being used and if Wayland is being used.

[Franklin] I don't understand why you're getting rid of __SWITCH_FOREGROUND_VT__ when its sole purpose is to give you the flexibility. Your hard coding rather than using the variable which can end up causing problems for Wayland. Just use the variable.

[Franklin] This isn't needed. Matrix GUI gets displayed full screen so there is no need for refresh screen.
