using xrdp with the Xorg window system to connect from win10 to ubuntu 20.04 in my local network. The connection is terrible slow. Compare to that a standard rdp connection (win10 to win10) via vpn through the internet is much faster then my local xrdp.

/etc/xrdp/xrdp.ini
max_bpp=32

After login via xrdp my desktop environment is:

~$ echo $XDG_CURRENT_DESKTOP
GNOME

Make sure to choose your connection speed in your RDP client experience tab. Set it to "LAN (10Mbits or higher)". This enables the RFX codec.

Assuming you use Xfce4, try disabling compositing with

$ xfconf-query --channel=xfwm4 --property=/general/use_compositing --type=bool --set=false --create

You could make this setting permanent in xorg.conf with

Section "Extensions"
    Option "Composite" "Disable"
EndSection

You can also work this out via GUI (install it if need be)

$ xfwm4-tweaks-settings

If yo use KDE, try disabling compositor as well, Settings -> Display and Monitor -> Compositor.

Also, try using a lower number of colors in the configuration of the client (16 bits instead of 32 bits).

Also, try these options in /etc/xrdp/xrdp.ini.

After doing a lot of research, I got good performance with these settings:

  • xfce4
  • xorgxrdp-glamor

In /etc/xrdp/sesman.ini and /etc/xrdp/xrdp.ini:

  • Policy=UBDI
  • max_bpp=16
  • xserverbpp=16
  • use_compression = yes
  • crypt_level=none
  • KillDisconnected=true
  • DisconnectedTimeLimit=0
  • tcp_send_buffer_bytes=4194304

Tweak for TCP (2x request buffer size):

  • sudo sysctl -w net.core.wmem_max=8388608

see https://github.com/neutrinolabs/xrdp/issues/1483

Disable compositor:

  • xfconf-query -c xfwm4 -p /general/use_compositing -t bool -s false

Setting "LAN (10Mbits or higher)" in the RDP Experience Tab solved the problem of slowness. Thank you.

For XRDP you will want to turn off Gnome's Animations:

Method 1 : Console

From console run the following as your current user:

gsettings set org.gnome.desktop.interface enable-animations false

Method 2 : Gnome Tweaks

Install the Gnome Tweaks tool:

sudo apt install gnome-tweak-tool

Run the Tweaks application which was installed.

  • Now use the hourglass at the top-left of Tweaks app and search for: animations
  • Switch Animations to off

These are the settings I changed which increased the speed and responsiveness for me:

  1. Open Remote Desktop in Windows
  2. Go to Display
    1. Display Configuration: 1280 x 1024
    2. Colors: High Color (15 bit)

RDP Display Settings

  1. Go to Local Resources

    a. Uncheck Printers

Local Resources

b. Click More in the above and Uncheck Everything

Local Resources > More

  1. In Experience > Choose Connection Speed: Modem 56 kbps

Experience Connection Speed

  1. Login to your Remote Desktop

  2. Open Terminal

Open Terminal

  1. Paste the following:
gsettings set org.gnome.settings-daemon.plugins.remote-display active false
gsettings set org.gnome.desktop.interface enable-animations false
sudo sed -i 's/max_bpp=32/max_bpp=16/g' /etc/xrdp/xrdp.ini && sudo reboot

Terminal Commands

Your remote desktop should be more responsive and less laggy now.
