I have two computers running Ubuntu 16.04 with Unity, and I'd really like to use the distributed multihead (Xdmx) software in order to use one of the computers as a second monitor, instead of just using two computers with Synergy. I replicated this error at work and home (I have two computers each location). First, on both machines I installed Xdmx:
sudo apt install xdmx
On the slave, I added the line xserver-allow-tcp=true at the end of /etc/lightdm/lightdm.conf to get slave to listen to host so that the host can grab its display. I then restart slave in order to have this take effect. On both machines, just to be safe, in order to let the X screen be grabbed, I do
xhost +
In order to make sure that slave is listening to host and I can grab the X display from host, I type on host telnet 192.168.99.20 6000 and it works (192.168.99.20 is the IP address of slave). Finally, on host I do
startx -- /usr/bin/X11/Xdmx :1 -display :0 -display 192.168.99.20:0 -ignorebadfontpaths +xinerama -norender
Both screens go black for a few seconds, and then come back on and I see a lot of output, with the error at the end:
xinit: XFree86_VT property unexpectedly has 0 items instead of 1
xinit: connection to X server lost
waiting for X server to shut down
Couldn't get a file descriptor referring to the console
Any help or suggestions you have would be amazing, thanks!
