I don't know a whole lot how to debug gnome-terminal, but one thing I know is that it has a "server process". I assume it's that process that's not starting. Can you try running /usr/libexec/gnome-terminal-server from xterm and see if it sheds any light on what's going wrong?

Comment 2 Debarshi Ray 2020-09-15 13:27:23 UTC

A bit of background on GNOME Terminal ...

/usr/bin/gnome-terminal is just a tiny little launcher. It sends a D-Bus message to /usr/libexec/gnome-terminal-server to request it to create a new terminal tab or window. The server binary is where most of the application lives.

Could you please open two xterm windows? In the first, do:

$ /usr/libexec/gnome-terminal-server

Then, in the second, do:

$ /usr/bin/gnome-terminal

What do you see in those two windows?

(Just be careful not to wait too long between those two commands.)

Comment 3 jari.kosonen4 2020-09-16 18:54:05 UTC

[jari@ENVY-17 ~]$ /usr/libexec/gnome-terminal-server
Non UTF-8 locale (ANSI_X3.4-1968) is not supported!
-> Here is strange result as this.

[jari@ENVY-17 ~]$ /usr/bin/gnome-terminal
# _g_io_module_get_default: Found default implementation gvfs (GDaemonVfs) for ‘gio-vfs’
# _g_io_module_get_default: Found default implementation dconf (DConfSettingsBackend) for ‘gsettings-backend’

# unwatch_fast: "/org/gnome/terminal/legacy/" (active: 0, establishing: 1)
# watch_established: "/org/gnome/terminal/legacy/" (establishing: 0)
-> Issues as this listed

But it is starting now.
It looks like setting 'export LANG=C' in .bashrc caused the problem of gnome-terminal not starting.

This is expected. Non-UTF-8 locales aren't supported.

Yes, exactly.
