XRDP stopped working on Debian 11. Only turquoise screen.

[ky8585]

Hello,

I'm not a developer - just a newbie user of xrdp. I came across the same problem under Debian 11.
After some upgrade xrdp stopped working and I only observe turquoise blank screen after credentials.
My config is as follows:
user@debian:$ dpkg -l| grep xrdp
ii xorgxrdp 1:0.2.15-1 amd64 Remote Desktop Protocol (RDP) modules for X.org
ii xrdp 0.9.21.1-1deb11u1 amd64 Remote Desktop Protocol (RDP) server

And the log file looks like this:

I said you to use the issue template.

I asked you what is the issue template.

[metalefty]

I explained the issue template. Sorry if you missed this.

When you raise a "bug report" you'll see the issue template.
https://github.com/neutrinolabs/xrdp/issues/new/choose

[metalefty]

I am not a native English speaker so I'm afraid my explanation wasn't very good. I think you need a detailed step-by-step guide to reach the issue template, here it is.

Is it clear to you now?

1. Click "Pull Request" at the top

2. Click green "New issue" button

3. Click green "Get started" button at bug report

4. Finally, you see the issue template, fill out it and submit.

[metalefty]

Could you also answer this? #2799 (reply in thread)

BTW, I think I get it now. Is this problem "same" as you have in mind at the beginning?
#2797
