Hi.

I have a XRDP setup, previously I had installed KDE and by default XRDP would login to that.

I have now installed XFCE as well and on login now you get a black screen for a second then quits.

However if my user has a ~/.Xclients file and I uncomment either of these

#startkde
#xfce4-session

XRDP loads into the desktop fine.

But I want the default to work - i.e for users with no ~/.Xclients file

Just to confirm with no ~/.Xclients I login and it asks for user/pass (as normal) but straight after entering details the application quits

All I want to do is for XRDP to load 'startkde/startplasma-x11' be default.,

Here are logs (/var/log/messages) from a login where the issue occurs

This is when I first login (by rdp client doesn't store the pass - which is why user login shows as failed initially) - i.e this part shows to the point where you get the XRDP login screen

Can anyone help me restore the default XRDP desktop session ?

XRDP is working fine with ~/.Xclients file.

On RHEL(etc), if the user doesn't have a ~/.Xclients or ~/.xsession file, the system will call the shell script /etc/X11/xinit/Xclients.

If this file is unchanged, the script should call KDE by default on your setup, as the supplied RHEL setup scripts do not support XFCE. It's odd it isn't, so I suspect there's more going on here than is obvious.

Again, if the file is unchanged, you should be able to get KDE working by creating /etc/sysconfig/desktop with this line:-

DESKTOP=KDE

You can try that. If that doesn't work, add some tracing to the file /usr/libexec/xrdp/startwm.sh by putting a set -x command near the top.

Thanks - I already had DESKTOP=KDE in /etc/sysconfig/desktop. This doesn't appear to be working.

If you get a trace from startwm.sh, post it here and we can look at it.

Here is the logs when adding set -x to /usr/libexec/xrdp/startwm.sh (with no ~/.Xclients)

Two things:-

  1. What's in /home/mcox/.xsession-errors?
  2. You're getting this error:- 
    /etc/profile.d/session_tmout.sh: line 1: TMOUT: readonly variable
    See Setting TMOUT can break xrdp on Debian/Ubuntu #2636 for why setting a readonly TMOUT is somewhat brittle and fairly pointless. It may or may not be related, but it's worth addressing I think.

  1. This is due to

readonly TMOUT
export TMOUT

Used for hardening - pretty sure its not connected (as previously when just KDE was installed the desktop worked without Xclients file.

e.g

[mcox@mcox ~]$ cat /etc/profile.d/session_tmout.sh
TMOUT=900
readonly TMOUT
export TMOUT

  1. You still appear to have a file /home/mcox/.Xclients. The test for it is triggering at the end of the log trace. Can you remove it, or mark it non-executable? The test is at line 85 in .etc/X11/xinit/Xsession.
  2. Suggest you surround the setting of TMOUT with a guard:-
# set a 15 min timeout policy for bash shell
if [ -z "$TMOUT" ]; then
	TMOUT=900
	readonly TMOUT
	export TMOUT
fi

Reasons are explained in the linked issue. If nothing else, it will prevent the odd error message in log files.
