How to use RDP connection on Ubuntu --XRDP

1. Install XRDP

First, install XRDP on Ubuntu by opening the terminal and entering:

sudo apt update
sudo apt install xrdp

2. Verify XRDP Installation

If the remote desktop shows a black screen, log out of the local session or follow these steps:
Edit /etc/xrdp/startwm.sh and add:

unset DBUS_SESSION_BUS_ADDRESS
unset XDG_RUNTIME_DIR

Restart XRDP service:

sudo systemctl restart xrdp.service

4. Desktop Optimization

Modify the following configuration file before remote connection:
Create ~/.xsessionrc and add:

export GNOME_SHELL_SESSION_MODE=ubuntu
export XDG_CURRENT_DESKTOP=ubuntu:GNOME
export XDG_CONFIG_DIRS=/etc/xdg/xdg-ubuntu:/etc/xdg

Restart XRDP service:

5. XRDP Performance Optimization

Adjust XRDP configuration parameters by editing /etc/xrdp/xrdp.ini and set:

tcp_send_buffer_bytes=4194304

Adjust system parameters:

sudo sysctl -w net.core.rmem_max=12582912
