I had the same problem with the Raspberry Pi4 (2GB).

Did you check the X server log file? It should be located in ~/.local/share/xorg/Xorg.0.log.

In my case it read:

...
(WW) Warning, couldn't open module fbdev
(EE) Failed to load module "fbdev" (module does not exist, 0)
...
Fatal server error:
(EE) no screens found(EE)
...

So I installed the missing fbdev module (took me some time to figure out the exact name):

$ sudo apt install xserver-xorg-video-fbdev

After that, startx started the desktop environment just fine. As for why this module was missing in the first place, I have no clue.

first thing you need to check your graph card information,for example "lshw -c display" or "lspci",the you have the BusID of graph card for example :pci@0000:01:00:00.After that You need to find /etc/Xorg/xconf in part of devices ,add one line BusID "PCI:1:0:0". Finally,reboot systsem.
