I used to open text files with sublime, and for Read-only files, I used to do :
sudo sublime. But now just suddenly the
sudo sublime command gives the following error :
(sublime:3931): Gtk-WARNING **: cannot open display:
sublime command is working fine. I tried the same with
gedit, and the same thing happened, with the error with gedit being shown :
error: XDG_RUNTIME_DIR not set in the environment. (gedit:3933): Gtk-WARNING **: cannot open display:
gtk, and tried
gksudo, still got the same error!
I searched the web and found these ways :
xhost +localhost: https://askubuntu.com/questions/614387/gksu-gtk-warning-cannot-open-display-0
ssh username@hostname -X
ssh username@hostname -Y
- How do I fix a "cannot open display" error when opening an X program after ssh'ing with X11 forwarding enabled?
None of the above worked.
What worked out for me was :
pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY sublime
I want to know why exactly am I getting this error, that too suddenly! Also, I want to get back to the
sudo sublime version, since it is easy to remember. How can I fix that?
Also, the recent changes I did to the system were :
Installed Mac theme for Ubuntu : http://www.noobslab.com/2014/04/macbuntu-1404-pack-is-released.html
Installed gksu(for gksudo)
Help would be highly appreciated!
