I have no access to local console.
I have access only xrdp.
As I understand from glxgears, nvidia driver not works at xrdp.

Is driver installed and running correctly? Is nvidia-smi shows GPU works?
Is it possible run nvidia driver in xrdp?

From internet I found solution.
Install x11vnc, configure run as daemon display 0 with port 5900.
Configure xrdp.ini connect to x11vnc.
xrdp.ini:

[X11vnc]
name=X11vnc
lib=libvnc.so
username=ask
password=ask
ip=127.0.0.1
port=5900
