I got a new computer (client), an apple silicon mac (macos 13) if that makes a difference. On the old computer, rdp to this server (debian) worked OK. From the new computer the first time I tried I got an xrdp login error as I did not save the password correctly . After fixing the password, rdp connection goes now directly to entirely black screen, the mouse cursor still looks like the mac's cursor when I move over the rdp window or click on it. Oddly, the rdp screenshot updated correctly to show my debian's desktop during the first few tries, now it doesn't anymore, not sure if I canged something.

I tried a few commons workarounds but it didn't work. Any ideas? Thanks!

  • I am not sure. May on the Debian system, uninstall XRDP, restart, instlall XRDP and then enable and start with systemctl. To RDP into a system you normally need to log off of the system your are trying to RDP into. – John Feb 22 '23 at 21:30
  • Perhaps your wrong password was saved as a credential and needs to be removed. On macOS, the [Keychain Access application](https://support.apple.com/guide/keychain-access/welcome/mac) is said to be used to view, modify, and delete saved credentials. – harrymc Feb 22 '23 at 21:40
  • nope... sadly reinstalling didn't work. password is not an issue either as I don't get a different outcome when I use "ask password" instead of a saved user – Fabri Ba Feb 22 '23 at 21:47
  • Try from a different computer as a Video issue between the new Mac and Debian may be the issue. I am not sure how to fix if this is the issue. – John Feb 22 '23 at 22:02
  • I thought of that but old computer was also a mac tho, plus I did get some screen time at the beginning as said just to get a "xrdp login error" screen, but still – Fabri Ba Feb 22 '23 at 22:05
