Hi,
I am trying to establish a remote connection to my lxde Desktop at my raspberry 4.
Should this just working?
I installed a fresh dietpi, with the software lxde and xrdp. I manage the autostart and autologin of lxde via dietpi-autostart. The connected monitor to my raspberry shows the lxde Desktop. Now I thought I could log into the lxde-Desktop via xrdp because my raspberry is normally running headless. But it shows some problems. Do I have to congfiure something?
Kind regards
I did a test and for me this was working without issues and further configuration. You could do a reboot to clean logs, try to connect a again and check xrdp log files afterwards to see if there is something specific.
journalctl -u xrdp*
OK, it least it should work this way. I wasn´t sure how xrdp works with lxde.
But:
I tried two, or three times to login again. The log shows:

Did you install LXDE as well as XRDP via dietpi-software? I’m asking since e.g. on Buster there is a known issue with XRDP on ARM which we work around, aside of some other issues, like failing mouse/keyboard input and such.
ah just as side not, not related. XRDP will create a virtual desktop. It will not be the physical desktop you will see once connected via RDP. Means, if you like to get the physical desktop, you would need to look into VNC. If you like to get XRDP/ virtual desktop only, there would ne no need to start into LXDE using autostart.
I have the same problem or “same” error message.
Since when?
Played around with the Kodi installation. Then wanted to do a reboot. Reboot was then done through the console via the xrdp connection to LXDE.
Since the reboot I can no longer connect to the root user via xrdp.
The login works with the dietpi user, then of course without root rights. But it works.
What went wrong here with the root user? Otherwise there are no problems with all applications and ssh login.
What I had done, xrdp and lxde uninstalled and reinstalled.
Likewise, one of the VNC connections tries to install, but the VNC services are not started…

Hi,
today I have tested TigerVNC with LXDE-Desktop. Works pretty good.
As client for Windows 11 I have downloaded the binary vncviewer64-1.12.0.exe: https://sourceforge.net/projects/tigervnc/
(Portable version)
Thank you
Kind regards
