[SOLVED]After installation lightdm and enabling auto boot, black scree

Hi guys,

with many difficults i get a fresh installation with systemd on my netbook.
I installed official catalyst, mate and lightdm. Everything "work", also i think at half, because the catalyst work.. after installation i launch:

lsmod | grep fglrx                - this get me the right output
fglrxinfo                              - this get me an error, no screen found(0) ?

But with startx, mate start without problems also i launch by a user (black) and when mate is ready and i open terminal i am "logged" by root :S
Anyway, i installed the lightdm as wiki and did these commands:

x:5:respawn:/usr/sbin/lightdm >& /dev/null
systemctl enable lightdm.service

Like a dumb i activated the auto boot mode without try if works or no.
Now when everything is ready and arch finish the boot process, i get a black screen without no words, terminal or something.
I only can do ctrl alt canc for reboot or shutdown.

There's a way to save an installation of a noobie?
Thanks, Gabriele.

Can you confirm you added this string to inittab?
You are supposed to use one of two methods either inittab OR systemctl .
Probably removing the string from inittab can solve the issue.

Like a dumb i activated the auto boot mode without try if works or no.

Maybe "autologin" ?

If you have some kind of linux live-usb or cd it is no problem. Simply revert the changes you made by booting with it, mounting your partition and editing files.
To disable the lightdm.service you do not even need systemctl running. Look for symlinks in /etc/systemd/system and /usr/lib/systemd/system/<target>.wants and delete (or move away) the lightdm.service SYMLINK.
I hope you have a live-usb ?

Re: [SOLVED]After installation lightdm and enabling auto boot, black scree

I did the command, without no error of output, so i suppose yes.

You think? I don t know because when i m on mate and i press logout for example, happen the same behavior..
Yes is for autologin, but here i want tell the auto boot for the module. On every boot that module is loaded in automatic.
Sure, i installed by live-usb.

So i mount the root, do the chroot to / and try to delete this symlink.
Right?

Thanks for the help!
Gabriele.
