As of lately, something about the login session breaks horribly when logging in via Lightdm/Slick-Greeter. I'm not quite certain what causes the issue, however here are the symptoms:
* The user when logged in, seems not be in any group except for its main group (e.g. `groups` yields just `username`). This is not the case when checking groups in TTY, after starting the X-server from TTY or when executing `sudo -u <username> groups`.
* Login works (with the described symptoms), but when trying to log out after having logged in from the greeter, the DM just restarts and apparently creates a new session (without requesting my password, so that the keyring needs to be manually unlocked)
* On every login attempt there seems to occur the following error in /var/log/auth.log:
```
Jul 12 16:20:32 GlaDOS dbus-daemon[1231]: [system] Rejected send message, 2 matched rules; type="method_ca
ll", sender=":1.220" (uid=1000 pid=11258 comm="lightdm --session-child 13 22 " label="unconfined") interfa

```
* Executing the command from the error message (`lightdm --session-child 13 22`) produces the following errors:
```

Things I have tried so far:
- `apt install --reinstall --purge slick-greeter lightdm*`
- `apt install --reinstall --purge dbus dbus-x11 dbus-user-session`
My System:
Architecture: amd64
System: Ubuntu 18.04 Budgie 64bit
Desktop-Manager: Budgie-Desktop
Session: budgie-desktop
Greeter: Slick-Greeter
I'm thankful for any clues on how to further debug these issues. I don't even know when they started - maybe an package update is to blame, but the only possibly relevant updates I have found in /var/log/apt/history.log are glx-related. I'll attach the latest apt history anyways. |

I don't even know when they started - maybe an package update is to blame, but the only possibly relevant updates I have found in /var/log/apt/history.log are related to the graphics driver/libraries. I'll attach the latest apt history anyways. |
