Running GNOME Terminal From a Zone

As I've mentioned before, I VPN into the Oracle Intranet from within a zone. Once I establish the VPN connection, I'm no longer able to SSH into the zone, which is a slight drag if I'd like to open a new terminal window. The solution is to launch a new GNOME terminal window from within the zone. However, this wasn't without some minor hurdles to clear, so I'm documenting the process for future reference.

I'm assuming your zone already has a user account and the X authority file utility installed so you can launch X applications. If not, follow Steps 2 and 3 from the entry Running Firefox From a Zone.

Of course, GNOME Terminal needs to be installed:

bleonard@myzone:~$ sudo pkg install gnome-terminal
               Packages to install:     1
           Create boot environment:    No
               Services to restart:     2
DOWNLOAD                                  PKGS       FILES    XFER (MB)
Completed                                  1/1       80/80      2.1/2.1

PHASE                                        ACTIONS
Install Phase                                160/160 

PHASE                                          ITEMS
Package State Update Phase                       1/1 
Image State Update Phase                         2/2  

At this point, you'd like to think you could just launch gnome-terminal, but alas:

bleonard@myzone:~$ gnome-terminal
**
ERROR:terminal-app.c:1450:terminal_app_init: assertion failed: (app->default_profile_id != NULL)
Abort (core dumped)

It turns out you also need to install the SMF services responsible for updating the GNOME desktop caches (I've already filed an issue for this):

bleonard@myzone:~$ sudo pkg install desktop-cache
               Packages to install:     8
           Create boot environment:    No
               Services to restart:     5
DOWNLOAD                                  PKGS       FILES    XFER (MB)
Completed                                  8/8   3125/3125    13.5/13.5

PHASE                                        ACTIONS
Install Phase                              3566/3566 

PHASE                                          ITEMS
Package State Update Phase                       8/8 
Image State Update Phase                         2/2 

After installing the package, wait a few seconds while the cache is built. You can verify it's complete when the GNOME Gconf Cache Builder service state changes to online:

bleonard@myzone:~$ svcs -l gconf-cache
fmri         svc:/application/desktop-cache/gconf-cache:default
name         GNOME Gconf Cache Builder
enabled      true
state        online
next_state   none
state_time   August 29, 2011 04:50:45 PM EDT
logfile      /var/svc/log/application-desktop-cache-gconf-cache:default.log
restarter    svc:/system/svc/restarter:default
dependency   require_all/none svc:/system/filesystem/local (online)

After which, gnome-terminal should start successfully:

bleonard@myzone:~$ gnome-terminal &


If for some reason you still run into a problem, try refreshing the GNOME Gconf Cache Service:

bleonard@myzone:~$ sudo svcadm refresh gconf-cache
