Hello,

I've Googled for a solution without success.

Today, I set up a Le Potato w/Armbian XFCE 22.04. All was well except only root had RDP access. After trying various ideas from the internet, I still can't get in as a normal user.

 

After the last attempt, I see this in /var/log/xrdp.log:

Basically, I get a black screen. 

For grins, I looked up how to enable RDP on my Raspberry Pi 4 running Raspbian Bullseye - basically do an apt-get install xrdp and done. Sure enough, I did that and sure enough, I am able to RDP into my Pi no problem.

So, what am I missing???

 

Thx.

Same issue here. Tried some workaround found on the forum, but basically the issue is simple : Only Root can be used to RDP. Using any other user just close the RDP.

( Tinkerboard S )

I had the opposite problem. When I tried to sign in as root I got a black screen and the RDP session terminated, but a normal Linux user RDP session is stable.

Turns out I had a .xsession file in root's home directory with a command that didn't exist. When I renamed this file to something else then RDP started correctly when using root.

I had the same problem. After deleting the .Xauthority file in the home directory, the RDP session remains stable. I did not check the sense of the cookie file .Xauthority or whether there are other and better workarounds. Let me know when you found the real bug or config problem.
