Lightdm slows i3 down

Dont know why but when i login and type startx i3 pops up instantly but when i use lightDm some X cursor appears and i3 takes a while to load

Is there any DM that puts you in tty ?

Re: Lightdm slows i3 down

I'm not sure why LightDM is slowing i3 down, but I bet you can circumvent the problem.

Try looking on the wiki. If you can't find anything, I'd be happy to point you toward a few things that might be of interest.

And I'd like that

I tried removing fprintd from lightdm PAM authentication and the same thing happened

So a did an arch install on a unused HD, installed the basic stuff for a test(Xorg, i3, lightdm and the greeters), followed the wiki(again) and when lightdm logs me in i3 starts instantaneously

Now i am pretty sure the cryptography is the issue but i dont know how to solve it(if posible)

You know you dont need a DM/greeter, right? They're just bloat anyway. Just set up to start X when you login to TTY1.

That's what I was going to suggest.

Re: Lightdm slows i3 down

There're also dialog based DMs search AUR for CDM
