OpenSolaris Desktop Optimization for Sun Ray
There are a number of configurations in the OpenSolaris Desktop that can be configured to better suit Sun Ray in terms of its resource usage. The following sections described what they are and how they can be set accordingly. The prior work for this page is based on [1]. Many of the settings listed have since been adopted as adopted as default values in the OpenSolaris Desktop, those settings are now omitted.

Desktop GCONF configuration

Preview as sound: gconftool-2 --type string --set \ /apps/nautilus/preferences/preview_sound never

Turn off the background screen gradient gconftool-2 --type string --set \ /desktop/gnome/background/color_shading_type solid

Wireframe mode gconftool-2 --type bool --set \ /apps/metacity/general/reduced_resources true

Limit nautilus thumbnail size. This is a configuration to decide whether to generate thumbnail or now. Choosing 5M which should cover most photo.

gconftool-2 --type integer --set \ /apps/nautilus/preferences/thumbnail-limit 5242880

Xscreensaver graphical "hacks" User's with Xscreensaver hacks enabled can consume significant resources even when they are away from their desk and their session is detached from a DTU. You can prevent graphical hacks from running on your server by removing these packages:

pkg uninstall SUNWxscreensaver-hacks pkg uninstall SUNWxscreensaver-hacks-gl

Tracker file indexing

Tracker file indexing is used by the desktop search. Creating the file index is a very CPU and disk I/O intensive operation. As each user owns it own file index and that can cause a very heavy load on the system when that file index creation starts running. To turn this off for every one, see Managing Auto-start applications

Other configurations to consider

What applications should not be auto-start in Sun Ray environment?

The mechanism for managing the auto-start of these applications is described at Managing Auto-start applications

New GDM login/logout fading effects

There are a couple of places where the fading effect will need to be addressed:

File Manager fading effect (as response to /desktop/gnome/background/picture_filename)

gnome-settings-daemon when nautilus is not used to draw the desktop background.
