Arch Linux User Repository

If upgrading from 0.9.x, please read the 'User Changes' section from the release page:https://github.com/neutrinolabs/xrdp/releases/tag/v0.10.0

There is one breaking change that require manual intervention but there are three other changes that will continue to work for now.

xRDP states: Users are urged to heed any generated configuration warnings and update their configurations. Later major versions of xrdp may remove these warnings, or introduce other behaviours for the affected parameters.

Generally a black screen indicates you are still "logged in" to your previous session.

How are you disconnecting from the first session?

Anyone else run into issues logging back into a previously active xrdp session following a restart of the service?

I had some applications open on my xrdp desktop and then logged out of xrdp, restarted the service, and was unable to log in again: plasma would start to load and then I'd get the generic black screen with xorg's massive black X cursor. All my googling tells me xrdp is supposed to clean up sessions when restarting.

To resolve, I went through all plasma and xorg processes and killed them (many were in a defunct state). Then when I tried to log in via xrdp, plasma started up just fine.

I'm using /usr/lib/plasma-dbus-run-session-if-needed startplasma-x11 in the .xinitrc if that helps.

As described earlier in comments in Manjaro the /usr/bin/Xorg is a script that decides to use /usr/lib/Xorg or /usr/lib/Xorg.wrapper. But when using /usr/lib/Xorg.wrapper you have to allow anybody to start X (Add allowed_users=anybody to /etc/X11/Xwrapper.config). Maybe there are more things to do.

The most easy way is to set param=/usr/lib/Xorg in sesman.ini. This setting will be saved, even with new versions of xrdp, since sesman.ini isn't overwritten by default.

Remember the default configuration is good if you are extendig a simple desktop system with xrdp. But when using a real xrdp server with multiple users and no local desktop its better to create a global xorg.conf https://aur.archlinux.org/packages/xrdp?O=60#comment-762246

Unable to login after upgrading xrdp to 0.9.21.1, here is part of my xrdp-sesman log.

I have noticed that this update has some changes in /etc/xrdp/sesman.ini and the path to Xorg executable is changed from param=/usr/lib/Xorg to param=Xorg (which results in /usr/bin/Xorg). When I tried to change the path back to /usr/lib/Xorg and restart xrdp.service, I was able to login to my desktop as before.

What is the difference between /usr/lib/Xorg and /usr/bin/Xorg? Or is something wrong with my PATH?

I am still too new to Arch and AUR to know how to make a pull request to the actual xrdp AUR package. I apologize for my ignorance but hope that someone can use the info below to upgrade their xrdp implementation to 0.9.21.1 - the latest release as of today.

I have updated the PKGBUILD and arch-config.diff from 0.9.19 to 0.9.21.1. They are contained in the following gists:

• PKGBUILD - https://gist.github.com/lbe/80b17cc2c9acb6a357ad64b2223db491

• arch-conf.diff - https://gist.github.com/lbe/3c2658466175f9ff8c541566e59ffc0d

Please note that this PKGBUILD does NOT contain a dependency upon tigervnc.
If you wish to use tigervnc, you will need to install it separately.

To use these:

1. git clone https://aur.archlinux.org/xrdp.git

2. Replace PKGBUILD with - https://gist.github.com/lbe/80b17cc2c9acb6a357ad64b2223db491

3. Replace arch-config.diff with - https://gist.github.com/lbe/3c2658466175f9ff8c541566e59ffc0d

4. Run make -si - This will sync the xrdp source and build the install package and then install the same if the build is successful

HTH, lbe

0.9.21 was released with a bunch of security fixes.

Here's my diff to simply update this package to 0.9.20: https://0x0.st/okCa.diff

The tigervnc dependency isn't fixed in the diff above, sorry.

@pdynarowski Cleanly rebuild the xrdp package instead, it builds fine with OpenSSL 3.

it doesn't work after update my manjaro (2022-11-2022)
journalctl -xe
lis 24 10:26:38 manjaro systemd[1]: xrdp.service: Job xrdp.service/start failed with result 'dependency'.

xrdp -ns
xrdp: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory

SOLUTION :)

pacman -Syu openssl-1.1

As others have asked, please remove the tigervnc dependency. fow0ryl's suggested optdepends should be perfect. Dependency on tigervnc is unnecessary and if you have tightvnc or realvnc installed it creates a dependency conflict and you are forced to uninstall them in order to install xrdp which shouldn't be the case.

Optional dependencies should typically be marked as optional.
