DietPi-Software | XRDP: Second attempt Xorg login without VNC server

[MichaIng]

Initial issue: #1727

• Since Stretch, xorgxrdp drivers are no fix part of the xrdp.
• Thus it needs to be installed separately so allow login via "Xorg" without VNC server.
• During my tests it then shows the desktop, but cursor and keyboard is not functional.
• Tested on multiple servers (Stretch + Buster, VM + PC), multiple clients (also freerdp client from DietPi system), multiple desktops and install of whole xorg package and some other packages to be sure nothing is missing.
• Due to the vast amount of tests it is nearly assured that the issue is the xorgxrdp drivers and/or how they are configured by default on Debian.
• Needs forwarding to xrdp devs: https://github.com/neutrinolabs/xrdp or https://github.com/neutrinolabs/xorgxrdp

Workaround via VNC server and Xvnc login works well on all setups.

A solution to test: neutrinolabs/xorgxrdp#164

Strange, now that a solution for the broken keyboard and mouse input has been found, on all my VMs (all Debian versions) it works OOTB. Will run some more tests on RPi and another SBC environment to be sure. If anyone else is in mood:

apt install xorgxrdp

Then connect via Windows Remote Desktop (or FreeRDP) not via Xvnc but via Xorg method.

@MichaIng
it's working fine on my Pi3B+

[MichaIng]

Tested on another notebook and here it does not work OOTB. Followed the above linked solution and added input device options to /etc/X11/xrdp/xorg.conf:

Section "InputDevice"
    Identifier "xrdpKeyboard"
    Driver "xrdpkeyb"
    Option "CoreKeyboard"
EndSection

Section "InputDevice"
    Identifier "xrdpMouse"
    Driver "xrdpmouse"
    Option "CorePointer"
EndSection

That solved the issue. I think to be sure, we should add this during install (and patch) as well:

grep -q 'Option "CoreKeyboard"' /etc/X11/xrdp/xorg.conf || sed -i '/^[[:blank:]]*Driver "xrdpkeyb"/a\    Option "CoreKeyboard"' /etc/X11/xrdp/xorg.conf
grep -q 'Option "CorePointer"' /etc/X11/xrdp/xorg.conf || sed -i '/^[[:blank:]]*Driver "xrdpmouse"/a\    Option "CorePointer"' /etc/X11/xrdp/xorg.conf

Applied the above workaround now as well, to be failsafe:
