I am new to Linux in general. So I may not have the right terminology.
I got myself a Raspberry Pi 4 to tinker with, and decided to install DietPi. I managed to install and logged in to the XFCE desktop. I added a new user as I didn’t want to mess with root or dietpi after reading that it is used for some services.

There is a switch user function on the top right corner but when I clicked on it, there was no response. So I decided to reboot the pi and then logged in as the newly created user. But I encountered this error:

(EE) Fatal server error (EE) no screen found (EE) Please consult X.org for support ...(EE) Server terminated with error (1) . Closing log file
xinit: giving up
xinit: unable to connect to X server; Connection refused
xinit: Server error

But I am able to login to the GUI using root but just not dietpi or the new user account.

I would appreciate any kind advice. Thank you.

you could try using LightDM login mask. To active run following

dietpi-autostart 16

after reboot, you should get a login screen for the desktop application. There you should be able to login with your new user.

It worked. Thanks, Joulinar.

After logging in, however, I wasn’t able to launch the system services via the Application menu such as Diet-config, Diet-launcher, Diet-xxxxxx. Is this the expected behavior? However, calling these services via the terminal is fine.

Yeah you would require sudo permissions for opening our scripts
