Systemd 237-3ubuntu10.43 landed this week in Bionic, and it enforces memory limits (LP: #1830746).
This makes slick-greeter crash, which people observe as "black screen with blinking cursor".
seb128 proposed that we need this commit backported:
https://github.com/linuxmint/slick-greeter/commit/f9af95ea3f.patch
Similar issues have also been discussed in LP: #1662244 and in https://github.com/canonical/lightdm/issues/55. |

[Test case]
Try to boot with an up to date Ubuntu MATE 18.04 system, without having autologin enabled. A black screen with a blinking cursor will appear, instead of lightdm/slick-greeter.
[Regression potential]
Low. It's an upstream patch that affects a specific small part of the code, which has been tested widely in more recent version of Ubuntu, like Bionic. I've also tested a package with this patch applied and it seems to work fine. |

[Regression potential]
The call was there to help protecting the password from being kept in memory an attacker could potential read. It's not an API which is right to use in that context though (the patch comments have details) and is simply not working as intended. In theory it could slightly weaken the code but that's better than having it no working. The same tradeoff was already made upstream in newer versions and in the different distros, unity-greeter already had the change in bionic. |
