I have Rapsberry pi 4B with 2GB of RAM. After some time I powered up Pi but not video output was shown. So I connected via ssh but there is no

I tried fresh installation of raspbian buster bot it didn't help. In
/var/log there is a log called
Xorg.0.log. In the end of this file I can find these messages:
Fatal server error: [ 111.497] (EE) no screens found(EE) [ 111.498] (EE) Please consult the The X.Org Foundation support at http://wiki.x.org for help.

Same messages are available when
sudo startx command is called but inside
dmesg I can't find anything related to the GPU.
Does anyone know what to do with it? I don't have connected anything special, just HDMI and it worked already, that's the weird thing on it.
EDIT: So it turned out, that my HDMI->VGA converter stopped working with RPI (with computer works well) and after reboot with connected HDMI monitor I can see
pi tty7 :0 16:41 3:32 1.36s 0.20s /usr/bin/lxsess
w command. Problem is that I need
:0 DISPLAY even if HDMI is not currently connected.
