el-topo Just checked my system, I don't have a xorg.conf
or xorg.conf.d
anywhere and everything is working fine 😉
You probably know this already but have a look at section 9.2 of the guide
Here's what I would do...
# cd /etc/X11
# mv xorg.conf old.conf
# exit
$ startx
If this works, you don't need xorg.conf and you can delete the file. If not,
# X -configure
# mv /home/${USER}/xorg.conf.new /etc/X11/xorg.conf
# exit
$ startx
You can now check where the issue was using
$ cd /etc/X11
$ diff xorg.conf old.conf
