This update for gdm fixes the following issues:

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).
