[Solved ]Can't xrdp make it work: crash after connected

glatswalker · 2025-07-07 23:39:43

Hello i'm having problem connecting to xrdp server.

I followed the wiki like:

yay -S xrdp xorgxrdp-glamor pipewire-module-xrdp

fill /etc/X11/Xwrapper.config with the content:

allowed_users=anybody
needs_root_rights=no

installed (for testing propuses)

yay -S xorg-twm xterm xorg-xclock

start it

sudo systemctl enable --now xrdp

copy xinitrc

cp /etc/X11/xinit/xinitrc ~/.xinitrc

without success.

i enabled debug mode on xrdp.ini and sesman.ini and here is the log:
https://0x0.st/8GWL.txt

xorg log:
https://0x0.st/8GW9.txt

thanks in advance

The posted xorg.log doesn't suggest the server has terminated, neither cleanly not w/ an error nor crashed.
is the process truely gone?

now that you mention it, the current behavior is that programs configured in .xinitrc continue to run even when the connection crashes.

i've installed the new version of the package but i'm getting black screen:

xrdp related log
https://0x0.st/8G6n.txt

xorg log
https://0x0.st/8G67.txt

xinitrc

#!/bin/sh

exec dbus-launch openbox-session

i tried with --exit-with-session but didn't work

[   457.185] (II) Server terminated successfully (0). Closing log file.

That server ran for ~3½ minutes and terminated cleanly.

Jul 08 14:40:21 rog xrdp[7986]: [ERROR] Attempting to send data to a channel that is not open. channel id 1, channel status CLOSED
Jul 08 14:40:21 rog xrdp[7986]: [ERROR] Attempting to send data to a channel that is not open. channel id 1, channel status CLOSED
Jul 08 14:40:21 rog xrdp[7986]: [ERROR] Attempting to send data to a channel that is not open. channel id 1, channel status CLOSED

And the error changed. Show up eg here:
https://github.com/neutrinolabs/xrdp/discussions/2383
Are you filtering/grepping the journal?? Don't.

exec dbus-launch openbox-session

Don't do that, this breaks session integration by not importing the relevant environment and then creating a different dbus session.

full log using journalctl -f http://0x0.st/8Glc.txt

and mi xinit

#!/bin/sh

exec openbox-session

also i changed my xrdp.ini

[Channels]

ok i rolled back Channels configurations to defaults and works with:

xfreerdp /u:glats /v:172.16.0.5 /cert:ignore /video /gfx:progressive:on

xfreerdp /u:glats /v:172.16.0.5 /cert:ignore /video /gfx

xfreerdp /u:glats /v:172.16.0.5 /cert:ignore /video /gfx:RFX:on

but not with

xfreerdp /u:glats /v:172.16.0.5 /cert:ignore /video /gfx:420:on

xfreerdp /u:glats /v:172.16.0.5 /cert:ignore /video /gfx:AVC444:on

i wonder why...

Have you considered using https://archlinux.org/packages/extra/x86_64/freerdp/ on the client as well?

i was using the xfreerdp client in mac installed thought homebrew. but now on fedora with remmina works fine.
i think i'm gonna set the thread as solved. now i'm gonna try to use the discrete cards instead with nvidia.

thank you very much!

for future reference downloading the reverse version worked: https://aur.archlinux.org/packages/xrdp#comment-1031495
