Hi,
I am trying to setup the xserver-xspice package to remotely connect to my Debian desktop. It claims to be more bandwidth efficient compared to VNC and there is even an Android client for the Spice protocol. I can get the xspice server started just fine. But I am having problems with the display manager.
In all cases described below, when I use Spicy (spice client) to connect to the desktop from a different machine, it connects fine, but only shows a black screen, indicating (from the documentation), that no display manager is running.
How can I get a display manager to see and connect to the xspice-xserver, so I can see it, when I connect to the remote machine? Also: Can you reproduce the issue on your desktop?
Full description:
I am currently on Debian 9 and pulled the xserver-xspice package from sid using apt pinning and conservative settings. My hardware is an Intel Skylake desktop computer using the Skylake gpu.
/etc/apt/preferences
Package: *
Pin: release o=Debian,n=stretch
Pin-Priority: 900
Package: *
Pin: release o=Debian
Pin-Priority: -10
Documentation and howtos on running XSpice are rather limited. I found and used those two:
I thus start the XSpice server using this command:
Xspice --xsession slim --config spiceqxl.xorg.conf --port 5920 --disable-ticketing --tls-port 0 :10
I tried a bunch of different display managers (sddm, xdm, gdm, wdm) and different settings for the vt, from :2 up to :40. When using the slim display manager, I get the following error message:
/usr/bin/X11/xauth: file /var/run/slim.auth does not exist
Invalid MIT-MAGIC-COOKIE-1 keyinterface_get_command: native
_XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed
_XSERVTransMakeAllCOTSServerListeners: server already running
(EE)
Fatal server error:
(EE) Cannot establish any listening sockets - Make sure an X server isn't already running(EE)
(EE)
All the other display managers do not work either, but also do not show this error message. Thus I tried stopping the display manager running locally on the desktop using this command, before I start Xspice:
systemctl stop sddm
Thus no X11 is running locally. Albeit I would like to both run a local X for local users and also connect remote users at the same time. Now when I use the command (same one again):
Xspice --xsession slim --config spiceqxl.xorg.conf --port 5920 --disable-ticketing --tls-port 0 :10
Xorg and the display manager (slim) come up on the monitor connected to the desktop, just like the "normal" xserver.
And again, as pointed out above, I only get a black screen, when I connect with Spicy. The display manager seems to only display on the locally connected monitor no matter what.
Thanks for reading,
