I just installed a jail I intend to use for remote desktop through Xrdp and ran into several issues with it. First some info on my system:
1. Login with
I quickly realized this doesn't work Xrdp interprets the domain-part sent by the client as the name of the session type to use. So, it finds a session type named like my Windows domain doesn't exist, picks the default type instead and tries to authenticate with PAM using only the
Is there a way around this behavior? My workaround for now is
2. Xorg with
The next problem I ran into was a crashing X-server. It logs the following:
For context, here's the full log on pastebin. Did I miss something here, could it be caused by my make.conf settings? Should I go and file a bug?
Anyways, next workaround: install net/tigervnc-server and use the
3. High-DPI displays, Xvnc doesn't seem to get client DPI correctly
From work, I have a Microsoft Surface Book, which has an insanely high-dpi (don't know the exact value) integrated display. When I connect to some remote Windows desktop, it all works well. When I connect to my Xrdp server, the Xvnc server doesn't seem to get a correct DPI setting -- everything is displayed in a tiny size, I can't read anything
Is this expected to work with Xvnc? Would it be expected to work with Xorg and the RDP driver? Is there anything I can do, configuration-wise?
4. Audio redirection
Looking at the packages that got installed, I assume audio redirection would work if I used
Now, is pulseaudio really my only chance to get audio redirection working? If so, would there at least be a way to have
Thanks for hints, ideas, solutions, comments ...

1. Login with
winbind
username in the form <DOMAIN>\<user>
I quickly realized this doesn't work Xrdp interprets the domain-part sent by the client as the name of the session type to use. So, it finds a session type named like my Windows domain doesn't exist, picks the default type instead and tries to authenticate with PAM using only the
<user>
part (after the backslash), which fails.Is there a way around this behavior? My workaround for now is
winbind use default domain = yes
in /usr/local/etc/smb4.conf, so winbind maps to plain usernames without a domain-part. But I'd prefer to have my domain-qualified usernames.2. Xorg with
libxorgxrdp.so
crashesThe next problem I ran into was a crashing X-server. It logs the following:

Anyways, next workaround: install net/tigervnc-server and use the
Xvnc
session type. This works, but if I understood correctly, is less performant than using the RDP driver for Xorg.3. High-DPI displays, Xvnc doesn't seem to get client DPI correctly

4. Audio redirection
Looking at the packages that got installed, I assume audio redirection would work if I used
pulseaudio
, as there's the audio/pulseaudio-module-xrdp package installed with Xrdp. Well, one reason I stay away from Linux if I can is some special kind of software that a) is designed in a highly-complex way while b) tries to replace any (simple) alternative, I guess you get what I mean, and you can see from my make.conf
above that my packages avoid pulseaudio
if possible.Now, is pulseaudio really my only chance to get audio redirection working? If so, would there at least be a way to have
sndio
output through pulseaudio, or do I really have to build all my packages with pulseaudio support? Thanks for hints, ideas, solutions, comments ...
