Lightdm(with slick-greeter) only starts AFTER tty login

I recently installed slick-greeter, and have wrestled with various configuration issues, and spent quite some time searching various threads across various distros for the issue I'm seeing.

That is, when I first boot, I am met with a completely black screen. However, when I swiitch to a TTY (all I have to do is switch to a TTY, I don't manually start the service or log in or anything), I can press ctrl + alt + f7 and the greeter starts successfully. When I check the lightdm status with systemctl, it says it's running nominally- however, I'm not sure how I'd find whatever errors existed prior to my login.

I checked the lightdm and xorg logs, and didn't see anything obvious, though I'm not experienced searching those particular logs. This makes me think the issue is tied to my user login somehow.

Do you all have any suggestions for further troubleshooting/mitigating?

Likely you just are not waiting long enough for the greeter to start. Or you are somehow watching the wrong virtual console and just need to hit alt-F7 sooner.

I'll try waiting longer, it's not the wrong tty though. I'll update this comment with the results. EDIT: It's not a matter of waiting. Whether I wait 2 minutes or immediately log in via tty, `lightdm` starts immediately after I log in via TTY.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
