Why you post Xorg.3.log instead of Xorg.0.log? lol Also you can try to startup without config directory: "/etc/X11/xorg.conf.d" , simply by mv folder to other name and restart display-manager service...

Are you follow the wiki? https://wiki.gentoo.org/wiki/Cinnamon

I post the logfile Xorg.3.log because it was the last created, yes I try to start the xserver without configfile in /etc/X11/xorg.conf.d/10-nvidia.conf but same problem.
Yes I follow the Gentoo Wiki, I think the problem come from the NVIDIA drivers with error message below :

Hi Babiz,

Thank you for your help, I created my xorg.conf with the nvidia-xconfig command I added this section "

[Babiz]

ok man, nvidia card look right, I see in your log
(WW) VGA arbiter: cannot open kernel arbiter, no multi-card support

This would be happen by running X server from user session ( I read this in oyher post here, write by another user https://forums.gentoo.org/viewtopic-p-8817439.html#8817439 ) and you need to check your display manager configuration you use (ex. SDDM lightdm or so)
Also check your login manager config, I see you rely on systemd...

You need to run X server from display manager not as single user session, if you want force single user startup (by type startx on terminal) you need to tweak more X server config, please read about https://wiki.gentoo.org/wiki/Non_root_Xorg

Another thing I see Keyboard0 and Mouse0 is useless configuration and you can remove safley
any Section "InputClass" in your X11 config folder/files, you true keyboard and mouse will be autodetected by query udev at every server startup.

For your Device section I think set something like this:

My /etc/X11/xorg.conf.d/nvidia.conf

Thank you so much for your reply and your help I appreciate, I looked at all informations you send me and did modifications in my X11 config file but the X11 server doesn't start.

I made a post on the Nvidia developper forum and they reply me below :

I’s a hybrid graphics notebook, primary graphics is the intel igpu. Please delete /etc/X11/xorg.conf.d/10-nvidia.conf and create a kernel that contains the i915 driver.

I'm going to create this kernel and I will keep you update.

I created a kernel with the intel i915 drivers by following this wiki https://wiki.gentoo.org/wiki/Intel but during boot I get these error messages :
