After the right graphic card (nvidia,ati, amd, intel, or internal) driver installation to your current linux kernel version.
File number order given by yours. Above shall be determined according to the order in case of need for file plug-ins extension numbers, according to the above ranking /etc/X11/xorg.conf file /etc/X11/xorg.conf.d/ and content number orders.
1. xx-nvidia.conf: Create driver configuration file for device first. This file only contain your specific driver information BusID, option for registery information. Only properties that are needed for the opening of the graphics card. Add to this feature, the feature graphics will happen only when initiated by the graphics card. These features will not be reinstalled when the next graphics card request. For example “/etc/init.d/gdm3 restart“
$ cat /etc/x11/xorg.conf.d/20-nvidia.conf

EndSection
2. xx-module.conf: File number order given by yours. This module your hardware capability for installed modules. Different device module can be used, if it usable.
$cat /etc/X11/xorg.conf.d/15-module.conf

Load “wfb”
Load “ramdac”
Load “evdev”
Load “synaptics”
EndSection
3. xx-monitor.conf: In monitor section use your first added configuration. For example from “xx-device.conf”
$ cat /etc/X11/xorg.conf.d/40-monitor.conf
Section “Monitor”

Option “NoLogo” “TRUE”
Option “ModeValidation” “NoDFPNativeResolutionCheck”
Option “ConnectedMonitor” “DFP-0”
# Option “MonitorLayout” “TDMS”
EndSection

4. If needed you add legacy xorg.conf file to /etc/X11/xorg.conf
5. Test your configuration order right or not right.
$ reboot # you see logo first
$ /etc/init.d/gdm3 restart # you can not see first logo but startx works.
$ shutdown # what see and configure your options.
Tthis configuration not need now xorg.conf file. When graphic card first load [Option “NoLogo” “TRUE”] not activate, then load monitor and screen [Option “NoLogo” “TRUE”] activate.
