Black screen and colored dots

Hello everyone! Today I decided to install ArchLabs on an M.2 SSD. The installation process is successful, but in the end I get the result, as in the screenshot: instead of Lightdm, a black screen and colored dots. What is the problem? Thank you.

What is your graphics hardware?

You can stop LightDM from loading by adding as a kernel command line parameter, see for the method.

Nvidia GeForce 9400 GT

Which driver is it using? I think you need either nouveau or the legacy nvidia-340xx driver.

If you don’t know which driver is in use then boot without LightDM (as I explained above) and run this command:

lspci -k | grep -iA2 'vga\|3d\|display'

Look for the “kernel driver in use” line.

The problem is localized. It was necessary to boot from a flash drive in UEFI mode, not BIOS. Thanks to all.
