Bug#893624: sddm is unusable in environments with large number of users

[Dmitry Torokhov <dmitry.torokhov@gmail.com>]

Package: sddm
Version: 0.15.0-1
Severity: important

Dear Maintainer,

In the newer versions of sddm (starting with 0.15) the greeter's UserModel
code is trying to de-duplicate user entries, and is doing so using O(n^2)
algorithm, which in large organizations means that the process takes about
an hour. User is simply presented with a black screen with mouse cursor.

There is a fix upstream:

https://github.com/sddm/sddm/commit/0edc3ffe15f2cdd89da40f4c830da8860bd9a13e

Please consider pulling it into distribution release(s).

Thanks,
Dmitry
