Need support to connect 3.5 LCD touch screen for Raspberry Pi Volumio

Did reinstallation of the 3.3.5 beta and all subsequent command, them rebooted.

The 3.5 LCD display stays white (unchanged).
After the installation and activation of the touch 3.3.5 plugin, the raspberry pi (PC) screen displayed the Volumio UI after prompting for theVolumio user and password ( as should); but after applying all the subsequent commands and reboot, the Volumio UI was not displayed after the user/password prompts. Toggling the Touch plugging on and off did not help. Should I reinstall the Plugging?

Thanks

Additional questions:
Should there be a /LCD-show directory?
Should the /usr/share/X11/xorg.conf.d be located under the /LCD-show directory?

Thanks again
