When I type gedit filename.c:
Unable to init server: Could not connect: Connection refused
(gedit:76): Gtk-WARNING **: 17:57:16.278: cannot open display:
This is the error is displayed and those numbers shown is random everytime I execute it,
when ls -l ~/.config/gedit
is entered
ls: cannot access '/home/blank/.config/gedit': No such file or directory
is displayed
how to fix this?
Most likely the problem is that gedit config files are owned by root.
This happens when you run sudo gedit in a terminal, that is wrong.
You can fix it by running
sudo chown -R $USER:$USER /home/$USER/.config/gedit
That will set correct ownership for these files.
Next time if you really need to run gedit with sudo (not recommended), do it this way:
sudo -H gedit
I has a similar issue when running Ubuntu on Windows with WSL2.
What it works for me was to to follow the instructions at https://wiki.ubuntu.com/WSL paragraph: Running Graphical Applications
Before I was using Xming, but gedit or any graphical visualization was not working. Then I tried with VcXsrv and after gedit worked!
