    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?

    Hello @stoli412 Please help us with the exact Linux name and version along with the kernel version. Also, please generate a couple of technical report ID's one with the tools installed and other with the tools uninstalled to check and assist you further.

    Hi @Abishek@Parallels, I've opened up a support ticket (2766586) and submitted a few technical reports as requested:
    343770941 - no Parallels Tools installed (xrdp works)
    343771822 - with Parallels Tools installed (xrdp does not work)
    Both of those technical reports were done with Mint 20.04, but this issue affects all linux versions I've tested (Ubuntu 18.04 and 20.04 and Mint 20.04). Ubuntu and Mint 20.04 are both running kernel version 5.4.0-39-generic.

    PS: Tests have been done with fresh installs (only xrdp and Parallels Tools installed) to rule out any other problems.

    Dear Parallels team, I have the same issue with Ubuntu 20.04, latest Parallels Tools installed and XRDP not working. Is there any update yet on this issue?

    Same here:
    Parallels Tools (PT) not installed, VNC works (tightvnc, tigervnc or X11vnc; all flavours)/ PT installed -> VNC stops working/ PT uninstalled again -> VNC works again

    Tested with Parallels Desktop for Mac - Pro Edition - 16.1.2 and
    Linux Mint 20
    Linux Debian Buster
    Linux Ubuntu 20.04.

    EDIT: VNC obviously doesn't completely stop working, it just seems as if the client wouldn't have sufficient rights to display the screen; cursor movements from the client to the (VM guestOS) server via VNC connection are transferred! clicking works, we can even double-click to open apps (although in blind-mode)

    EDIT2: We have narrowed it down a bit...
    This is how it's reproducable and what we followed for testing purposes: https://community.linuxmint.com/tutorial/view/2334
    (We used a fresh standard installation of Mint 20 made available by Parallels.)
    Then: Reboot the server and do not login.
    Access the server from another VNC client; all is good.
    Log into the server using the keyboard of the VNC client; the display stops refreshing and freezes on the VNC client; the monitor plugged into the server, though, shows the correct desktop and one can use mouse and keyboard to control the server.

    So this issue was submitted in May 2020. It has been escalated to the dev team but has it been closed? I've got the suspicion that Parallels prioritizes its own development toys and user bugs are not among these.

    Same issue here with Parallels Pro 16.1.3 and Ubuntu 20.04. It kinda breaks the « Pro » purpose of the App.
    Please dear Prl team do something.
