Blackscreen not solved by current alternatives.

igorfk commented 2 years ago

Hi!

Debian 11 with xrdp 0.9.12 from pre compiled packages (apt install xrdp xorgxrdp)

I was connecting to the XRDP server very well, only trying to make USB redirection work for me, but just modifying the "FuseMountName=..." line in sesman.ini and various other parameters in the RDP clients, after one of the several service restarts I could not log anymore just that black screen after the default XRDP login screen. Tried several suggestions that I find over the web and here in the project but none work, as:

Tried to log with an account different from root and not already logged in the system, give me the black screen. (reboot/restart service)
Tried to uninstall dbus-user-session and install dbus-x11, rebooting, and still with the black screen issue (reverting back to dbus-user-session and remove dbus-x11 and reboot/restart service)
After adding the folowing lines to /etc/xrdp/startwm.sh
```
unset DBUS_SESSION_BUS_ADDRESS
unset XDG_RUNTIME_DIR
```
Just before the "test -x /etc/X11/Xsession && exec /etc/X11/Xsession" line. Still black screen, after that I revert back the file and reboot/restart service.
Modified /etc/X11/Xwrapper.config from allowed_users=console to allowed_users=anybody Still black screen, then I revert back the file and reboot/restart service.

Tried to log with xfreerdp, rdesktop, mstsc, and from different hosts, always black screen after the XRDP login screen.

Any clue on how can I get to the session?

These are my logs and configuration files (clients and server in the same VLAN), now, without caring with usb redirection:

It looks like /etc/X11/Xsession is failing to start a session for some reason, and retrying something.

I can't find any sleep commands in my session startup scripts.

Can you post the output of this command?

DISPLAY= /bin/sh -x /etc/X11/Xsession

Don't miss out the space after DISPLAY=

If that command ends with lines something like this:-

+ ERRFILE=/home/username/.xsession-errors
+ [ -w /home/username/.xsession-errors ]
+ [ ! -L /home/username/.xsession-errors ]
+ chmod 600 /home/username/.xsession-errors
+ stat -c%s /home/username/.xsession-errors
+ [ 388129 -gt 500000 ]
+ exec

you'll find more information in ~/.xsession-errors. That would be useful to see too.

First: Thank you for all your work in this project @matt335672 and all other Devs

Second: I'm dumb.

Trying to make USB redirection work for me, eventually I executed the following command:

cp /etc/xrdp/startwm.sh /etc/X11/Xsession

instead of

cp /etc/xrdp/startwm.sh /etc/xrdp/startwm.sh.backup
cp /etc/X11/Xsession /etc/xrdp/startwm.sh

I was following a good article but the problem was... me.

Restoring the original /etc/X11/Xsession file did the trick: XRDP server running without problems, get in the session and everything smooth.

matt335672 commented 2 years ago

Well, it had the interesting side-effect of giving us something unusual to think about!

I'm very sure you're not dumb - we all fat-finger stuff from time-to-time.

Thanks for getting back to us.
