  Security issue fixed:

  - CVE-2019-3825: Fixed a lock screen bypass when timed login was enabled
  (bsc#1124628).

  Other issues fixed:

  - GLX applications do not work well when the proprietary nvidia driver is
  used with a wayland session. Because of that this update disables
  wayland on that hardware (bsc#1112578).

  - Fixed an issue where gdm restart fails to kill user processes
  (bsc#1112294 and bsc#1113245).

  - Fixed a System halt in the screen with message 'End of ORACLE section'
  (bsc#1120307).

  - Fixed an issue which did not allow the returning to text console when
  gdm is stopped (bsc#1113700).

  - Fixed an issue which was causing system hang during the load of gdm
  (bsc#1112578).

  This update was imported from the SUSE:SLE-15:Update update project.
