I'm running Ubuntu 18.04 on Windows Powershell on Windows 10. I installed XMing and PuTTY and configured them so that X11 forwarding is turned on. After all this, and installing x11-apps and running xeyes, it tells me "Error: Can't open display: 0.0". I tried changing the DISPLAY to 0 and 'localhost:0.0, but nothing. I installed several packages, many of which will probably end of being unnecessary. I've tried just about everything in the responses both of these questions:
https://unix.stackexchange.com/questions/67111/x-cant-open-display-0-while-display-variable-is-correct?newreg=2fece9554c164efd90a2726a9c526fb5
https://unix.stackexchange.com/questions/1596/can-i-launch-a-graphical-program-on-another-users-desktop-as-root , but
who | awk -v user="$target_user" '$1 == user && $2 ~ "^:" {print $2}'
returns nothing and
xhost +
gives me the same display error. I tried various configuration files such as xauth, /etc/X11/Xwrapper.config. It might be important to note that xinit
returns the fatal error no screens found
and /var/log/Xorg.0.log
shows many errors
dbus-core: error connecting to system bus: org.freedesktop.DBus.Error.FileNotFound (Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory)
open /dev/dri/card0: No such file or directory
open /dev/fb0: No such file or directory
No devices detected.
I need to be able to use image tools like ds9 for my research and have been unable to do so, so any help would be very much appreciated.
