Xrdp: XRDP session immediately closes after loggin in.

[faya9551]

Hi

I have xrdp installed on both RH 7.6 and 7.7 both are showing the same behavior. Can you please suggest if I have to make any config changes for this to work?
I do not have file on Redhat : /etc/xrdp/startwm.sh

tigervnc.x86_64                                      1.8.0-17.el7                 @rhel_7Server_x64_localrepo

Sorry this is not a solution!

The same problem is happening with Xubuntu 18.04 LTS, Xubuntu 19.04.
When I try to connect through mstsc on Windows 10, I get a black screen after login and exit.

I searched for half a day and tried many solutions but showed the same problem..

Below is the log when connecting.

I think it's an xorg problem, but I haven't found a solution yet.
Do you know how to solve this problem? or bug?

Hi @faya9551

Following may be the reason for your issue:

1. Please check whether all the desktop manager component been installed if not please use yum groupinstall "KDE" and GNOME
2. Check you home directory whether you have any .Xclients file.
   if yes change the file permission to chmod +x .Xclients and add the startkde/gnome-session inside this file.
   NOTE: Empty file will be create the session close

I am getting the same thing, but it only seems to happen if I log into the machine locally and then, without logging out, try to log in with xrdp. If I am not logged in on the machine and I try to log in with xrdp then it works. Also if I disconnect from an xrdp session and a reconnect to the logged in session it still works. That's happening on a Pop! OS 19.04 VM.

Hi people!
My XRDP stopped working few weeks ago. Then I started working with the xfce4. But It does not allow me to see some applications for example kivy applications. So I started to dig out how to solve this issue. But I can't see how. Using xrdp i got the following status:

When I am trying to run Kivy applications in xfce4 this is what I got:

Currently experiencing the same issue when attempting to xrdp into a Termux chroot running in Android 10 - Samsung Galaxy Note 10+

Ubuntu version is 20.04

VNC setup functions when using vnc server and vnc client:

vnserver > vnc client : ok
vncserver > rdp : not ok
xrdp > rdp client : not ok

[mailinglists35]

this worked for me on oracle linux 8 minimal install with xfce4 from epel:

echo xfce4-session > $HOME/.xsession chmod +x .xsession

there are lots of failsafes but when the system is minimally installed there is really no failsafe on ol8 so failing to launch a desktop environment will result in normal action = ending the xorg xrdp session

places to look to see how things are tried:
/usr/libexec/xrdp/startwm.sh <- this is where searching for a desktop session or window manager begins

inside you will see it is searching for /etc/X11/xinit/Xsession /etc/X11/Xsession /etc/X11/xdm/Xsession etc... look inside those which eventually you'll see failsafes desperately trying $HOME/.xsession, $HOME/.Xclients, /etc/X11/xinit/Xclients, xsm, xclock, xterm, twm, firefox... but NONE of these come into a minimal ol8 installation! that's why you HAVE to intercept these and put something into your $HOME/.xsession or $HOME/.Xclients and make it executable (scripts check if they are executable)

if you want it system-wide, put this in /etc/sysconfig/desktop (/etc/X11/xinit/Xclients looks for it):
PREFERRED=/bin/icewm-session
(or /usr/bin/xfce4-session or whatever unusual wm session you have - make sure the binary is there, for example xfce is installed by xfce4-session rpm)

This worked for me in Ubuntu Bionic. Thanks very much for posting it.

chmod +x .xsession

worked for Ubuntu, thanks a lot.
