A few months ago I bought new 4K monitor, to have AMD Freesync I followed the info from Arch wiki, I created a file /usr/share/X11/xorg.conf.d/20-amdgpu.conf containing:

Code: Select all

Section "Device"
	Identifier "AMD"
	Driver "amdgpu"
	Option "TearFree" "true"
	Option "DRI" "3"
	Option "VariableRefresh" "true"
EndSection
And it worked, I can see in the log that variable fresh rate is enabled.

A few months pass, I forgot about this, and now I tried to remote access this PC with Remmina from another desktop as I did months ago and it was working fine, but it is not working now, I had some error in ~/.xorgxrdp.10.log about /dev/tty0 permission, googling for this it looked like a recuring bug about rootless X and maybe user group or all kind of VT stuff etc, but I didn't changed any of this when I installed MX and it worked. I installed MX on another latop to test and xrdp is working fine, so I needed to investigate.

After a few hours scratching my head, I saw that in the .xorgxrdp.10.log it was loading the GPU hw for remote desktop?

Code: Select all

[  4653.251] (**) ServerLayout "X11 Server"
[  4653.251] (**) |-->Screen "Screen (xrdpdev)" (0)
[  4653.251] (**) |   |-->Monitor "Monitor"
[  4653.251] (**) |   |-->Device "Video Card (xrdpdev)"
[  4653.251] (**) |   |-->GPUDevice "AMD"
It looks odd, so after some googling it looked like the culprit, to test I removed my /usr/share/X11/xorg.conf.d/20-amdgpu.conf file and xrdp is now working, so when it parse the /usr/share/X11/xorg.conf.d/ folder it was loading the GPU because of this.

Now, how can I bypass this to have both VRR working locally, and xrdp working?

I added the "AutoAddGpu" "off" option in /etc/X11/xrdp/xorg.conf but it still load the GPU

Code: Select all

Section "ServerFlags"
    # This line prevents "ServerLayout" sections in xorg.conf.d files
    # overriding the "X11 Server" layout (xrdp #1784)
    Option "DefaultServerLayout" "X11 Server"
    Option "DontVTSwitch" "on"
    Option "AutoAddDevices" "off"
    Option "AutoAddGpu" "off"
EndSection
Any idea?

Found it, I need to tell X the name of the GPU so it will not auto load others. I don't need the AutoAddGPU option at all.

in /etc/X11/xrdp/xorg.conf in the Screen section, add the line
GPUDevice ""
like this:

Code: Select all

Section "Screen"
    Identifier "Screen (xrdpdev)"
    Device "Video Card (xrdpdev)"
    GPUDevice ""
    Monitor "Monitor"
    DefaultDepth 24
    SubSection "Display"
        Depth 24
        Modes "640x480" "800x600" "1024x768" "1280x720" "1280x1024" "1600x900" "1920x1080"
    EndSubSection
