Nvidia driver issues. Nividia diver looks to work but I only get black screen.

Hi everybody.
I recently got an new laptop (Asus X555UB).. Slackware works smoothly... but Im having issues with the Nvidia driver.

When I do startx, without any xorg.conf, xorg is working with no 3d acceleration.

When I startx, with a xorg.conf file "I did" (nvidia-xconfig, xorgsetup you know...) to use the nvidia drivers... the screen just got black/blank. I can change between virtual consoles (Ctrl + alt + Fx..etc).. but there is not graphics...

This is what I did:

1. I installed the driver from slackbuilds.org via sbopkg. -sbopkg -i nvidia-driver-
2. I uninstalled and blacklisted the nouveau driver. -done by xf86-video-nouveau-blacklist-
3. I checked the modules.. and everything looks fine.
4. I "wrote" an xorg.conf, even when I know is not need, to start xorg with the nvidia driver.
5. startx.. I dont use a login manager.
6. Looks like its working but only see a black screen.

There goes the files:

I need to fix this because I want to run blender and ..I dont want to change Slackware for something else..it just works. I cant figure out, I dont know what Im missing.

Thank you for the help.

pd: sorry for my bad english.
