Not working on recent debian (raspbian bullseye)

apt install xrdp works, but windows remote desktop login only gives a black screen, when credentials were saved and a login screen if not, but no active desktop even if desktop environment is present and working, by normal pi desktop install.

@goofyseeker311 - have you seen #2060? This looks very similar, based on the information you've given us so far.

@goofyseeker311 - have you seen #2060? This looks very similar, based on the information you've given us so far.

making a new user without any other adjustments worked directly, like was said in the #2060 the raspbian default primary sudo user (default account-name pi) cant do xrdp directly, same settings, different account.

the default isntall login account in raspbian seems to be special in some ways, something like that root-able cannot login with xrdp, security prevention from the developer side. ie, Xwindowsystem refusing connection because root/sudo-rights.

The reasons for all of this, together with known remedies are in #2060. In particular, see this post.

sudo deluser pi render worked for me.
