Cliff Zhao 517b9bb8f7 Accepting request 631911 from home:qzhao:branches:Base:System
Update to version 0.9.3+git20180827.0a66272: Ensure tty is closed on deactivate, If plymouth doesn't get explicitly activated then when GDM tries to deactivate it, the deactivation request is a noop.

Subject: force fb for cirrus and bochs, force drm otherwise
References: bsc#888590, bsc#980750
DRM does not work well with cirrus and bochs (no display) but the framebuffer driver
prevents DRM drivers from loading.
As we need to support cirrus for libvirt and bochs for QEMU, we cannot just remove support for frame-buffer.
