xorg does not start with xorgxrdp 0.9.19 and xrdp 0.9.21.1 about xorgxrdp HOT 4 CLOSED

Hi @Blind55

First things to check:-

• sesman log file. That contains the command which is used to start the Xorg server. Try that on the command line, and see what you get.
• ~/.xorgxrdp.*.log files contain information on the operation of xorgxrdp, if they exist at all.

Please update us on what you find.

from xorgxrdp.

@matt335672 Many thanks for your reply.
Below is the section of the xrdp-sesman log.

Using my user account, I attempted the command line
Xorg :11 -auth .Xauthority -config xrdp/xorg.conf -noreset -nolisten tcp -logfile .xorgxrdp.%s.log
via IPMI, and that caused an error:
Invalid argument -logfile with elevated privileges
Running the command line without the apparently offending -logfile argument (and redirecting the output) seemed to have worked (although I didn't see a graphical screen, which I assume is ok):

Unfortunately, there is no ~/.xorgxrdp.*.log file from the 'regular' call when logging in with freeRDP.

A problem here is that sesman is starting Xorg without a path. That runs the Xorg wrapper and that won't work on modern systems.

If you don't know what I mean by "Xorg wrapper", this command will show you that the standard Xorg command is just a shell script:-

cat $(which Xorg)

Have a look in /etc/xrdp/sesman.ini. Under the [Xorg] section there will be a param=Xorg line. From memory for Arch that should be param=/usr/lib/Xorg instead.

You can check that by seeing if this command works on the command line:-

/usr/lib/Xorg :11 -auth .Xauthority -config xrdp/xorg.conf -noreset -nolisten tcp -logfile .xorgxrdp.%s.log

Have I explained that well enough?

Thank you again for your quick, and very clear, reply. I am getting:

$ which Xorg
/sbin/Xorg
$ ls -al /sbin/Xorg
-rwxr-xr-x 1 root root 271 Dec 19 05:35 /sbin/Xorg

In Arch, /sbin/ is just a link to /usr/bin, and - as you say - that script either executes Xorg.wrap (if it exists, to run with suid), or /usr/lib/Xorg directly. I have made the change you suggest to the /etc/xrdp/sesman.ini file:

[Xorg]
; Specify the path of non-suid Xorg executable. It might differ depending
; on your distribution and version. Find out the appropriate path for your
; environment. The typical path is known as follows:
;
; Fedora 26 or later : param=/usr/libexec/Xorg
; Debian 9 or later : param=/usr/lib/xorg/Xorg
; Ubuntu 16.04 or later : param=/usr/lib/xorg/Xorg
; Arch Linux : param=/usr/lib/Xorg
; CentOS 7 : param=/usr/bin/Xorg or param=Xorg
; CentOS 8 : param=/usr/libexec/Xorg
; FreeBSD (from 2022Q4) : param=/usr/local/libexec/Xorg
;
param=/usr/lib/Xorg
; Leave the rest parameters as-is unless you understand what will happen.
param=-config
param=xrdp/xorg.conf
param=-noreset
param=-nolisten
param=tcp
param=-logfile
param=.xorgxrdp.%s.log

This did solve the issue. Thank you very much again.

[I also looked back in the AUR page for xrdp (something I should probably have done first), and there the suggestion that you make was the same - I apologize profusely for the noise here.]
