failed to start lightdm (Result: exit-code)

i have installed fresh arch with mate DE and after installation reboot i got black screen so in tty2 i saw status of lightdm......

#systemctl status lightdm
● lightdm.service - Light Display Manager
     Loaded: loaded (/usr/lib/systemd/system/lightdm.service; enabled; vendor preset: disabled)

Apr 26 04:46:04 arch systemd[1]: Failed to start Light Display Manager.

i have installed everything according to arch wiki, after searching for this problem i saw people had solved it by installing  xf86-video-intel, so i also did this but no solution.

hear is lightdm debug log

i also saw that someone's greeter in /etc/lightdm/lightdm.conf was not properly set, so wasn's mine, so i corrected it by adding  'greeter-session=lightdm-gtk-greeter' and rebooted, but no help

hear is log from 'journalctl -xe'

Re: failed to start lightdm (Result: exit-code)

1. Please edit your post and use code tags: https://wiki.archlinux.org/index.php/Co … s_and_code

2. There is no Arch with Mate. You install Arch. The you install and test X is working, before you start piling on other applications that require X to run.

Re: failed to start lightdm (Result: exit-code)

Please use code tags for commands and their outputs.

(==) Using config file: "/etc/X11/xorg.conf"
(==) Using system config directory "/usr/share/X11/xorg.conf.d"
(EE)
Fatal server error:
(EE) no screens found(EE)
(EE)

The config file is causing X to fail.  Why is the system using an xorg.conf?  How was it generated and what is its contents?
What GPUs are present in the system?

lspci | grep -e VGA -e 3D

Re: failed to start lightdm (Result: exit-code)

As the system has a hybrid GPU configuration using an Nvidia GPU see NVIDIA_Optimus.
Also note quote tags and code tags are different.

That is not an error message: https://bbs.archlinux.org/viewtopic.php?id=57855

Paste the xorg log for the basic twm/xorg session as described in the wiki.
