apport information
** Description changed:
After booting, the first screen appears black, then I need to make a
click with mouse to call the login screen. and it happens when I lock
the screen, it goes blank. But it does not happen with a laptop/desktop
with single primary panel, only happens with a system with external VGA
panel and with lightdm+lightdm-gtk-greeter combination as installing gdm
fixes the issue.
