I've recently migrated from VirtualBox to Parallels and I'm having an issue with xrdp inside Ubuntu (both 18.4 and 20.4). I've used this script for years to properly set up xrdp inside Ubuntu: http://c-nergy.be/blog/?p=14888 However, upon migrating my VMs to Parallels and installing Parallels Tools, RDP access is now broken; starting an RDP session is greeted with only a blank screen. If I uninstall Parallels Tools, RDP access works again. I thought this might be some issue with VM migration, so I set up a fresh Ubuntu VM to test and got the same results. Can anyone explain what Parallels Tools does to the video driver and/or xorg configuration that causes xrdp to fail? Is there any way around the issue?
