xrdp is quite slow
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
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.
