Dear Alexander, |

|
3 |
Thanks for pointing to this bug! |
4 |
|
5 |
I'll give another try to systemd. |
6 |
A duplicate of bug 472098 also contains important information: |

https://bugs.gentoo.org/show_bug.cgi?id=455938 |

According to this bug it's enough to add polkitd to the PROC_GID group. |
9 |
Now I know what was my problem with gdm-3.6! |
10 |
It's a pity I hadn't found this bug earlier. |
11 |
|
12 |
Sorry for the noise. I'll retry systemd transition. |
13 |
|
14 |
Thanks: |
15 |
Dw. |
