changing to gdm and rebuild the modules didnt helped

Yesterday I restored my arch / antergos from a full drive backup.
After mounting efi, boot, system and home partition from a live system i chrooted and did and grub repair.
The system also boots again.

Unfortunately, I can not log on to the graphical interface (gnome) and will be thrown back to the ligthdm login window.
login to another terminal z.b. tty1 works fine

Xorg.0.log reports:

EE failed to load module "intel" (module does not exist)
EE failed to load module "nouveau" (module does not exist)

thought maybe i need to
mkinitcpio -p linux but i think it should not be necessary with restore on the same hardware.

Apparently, I did not pay attention to restore something.
ideas and help are welcome

Thanks and hello dear antergos users
