When we are running without fbdev, transitioning from the login screen to X or gnome-shell/wayland will cause a vt switch and the driver will disable svga mode, losing all modesetting resources. However, the kms atomic state does not reflect that and may think that a crtc is still turned on, which will cause device errors when we try to bind an fb to the crtc, and the screen will remain black. Fix this by turning off all kms resources before disabling svga mode. Cc: <stable@vger.kernel.org> Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Sinclair Yeh <syeh@vmware.com>
