Hello, the new Bullseye version of xrdp is identical to the version in Bookworm. Thus the underlying problem is probably more complex and I don't suspect that something is wrong with xrdp itself but more likely with a configuration option or related software packages which do something different than in Bookworm.
I have tried to reproduce the problem on Bullseye with Gnome 3 installed. The problem here is that gnome-remote-desktop appears to interfere with xrdp, so I'm not totally sure what is caused by Gnome and what might be a bug in xrdp. Then I restarted the session with Gnome in Xorg mode and a remote connection to the xrdp server succeeded. However I got a black background instead of the normal wallpaper I have. Applications were shown correctly though. I definitely need more information about your setup or xrdp in general to debug this issue. Possible reasons for the behavior may be: 1. TLS / connection problem ? Did you do "adduser xrdp ssl-cert" ? Maybe a new TLS configuration option in 0.9.21.1? 2. graphic drivers ? I read that hardware accelerated drivers may cause such problems. Maybe try to disable them and use software rendering only? LIBGL_ALWAYS_SOFTWARE = true Please also upload the following log files: /var/log/xrdp-sesman.log /var/log/xrdp.log ~/.xsession-errors and journalctl -S -2m or something similar may provide more information about error messages, etc. ~/.xorgxrdp.10.log seems to belong to xorgxrdp. The package is only recommended but I wonder if the problem is potentially caused by it. xrdp is a build- dependency which suggests it might need a rebuild? But on the other hand then recommending the package would be wrong and it should be added to Depends. Someone else would have stumbled upon this sooner I guess. Regards, Markus
