[Lhymna]

Hi everyone,
I have installed MATE. and it's working with startx but not when i try to log on lightdm.
My user is in the group "video"
any help pls ?

I don't understand, but does Lightdm's screen appears?
And makes it login you, but after it don't enter in MATE?
or don't you even see lightdm screen?

Sorry for my poor english and thanks for the reply!
When I start my system, Lightdm start and i can try to log with my user. But when I try to log, lightdm doesn't work, he stay on the Lightdm's screen without any error messages.
But when I use the command startx, i boot on MATE.

Once you emerge lightdm, the steps to follow are these:

- configure file "/etc/conf.d/xdm" (DISPLAYMANAGER="lightdm")

and then (if you use OpenRC):

In lightdm.conf file, in line "greeter-session" you have to put the name of your greeter.
That greeter's name you can find it in /usr/share/xgreeters and sound like this:

lightdm-kde-greeter

In your case it isn't kde

Thanks for the reply,
My bad, I just recreate an other group and an other user with the correct groups like this :

addgroup
useradd -m -g mygroup -G users,audio,cdrom,portage,video,wheel

I think my old user was by default in his own group and maybe it create conflits, i don't know if it could be possible?

I'm sorry and thanks a lot for the fast reply !

It seems that X starts ok, so it's something else that's wrong. I'd guess permission issue.
Can you post contents of /var/log/lightdm/lightdm.conf?
