Troubleshooting Tips

Solution
• Check to see that the appliance is plugged in.
• The appliance may be in PowerSaver mode. Move the mouse to
activate the display.
The Sun Ray 150 appliance supports only 1024x768@60Hz screen
resolution. If the image sent by the Sun Ray enterprise server is of a
higher resolution, it will create a "panning" effect on the appliance.
If this effect is not desirable for your desktop, there are two ways to
change the resolution:
• Open a terminal window and type the following command:
/opt/SUNWut/lib/utxconfig -r 1024x768
If you type this command with your smart card inserted in the
appliance, the new display setting will be associated with the smart
card and will follow your smart card to any other appliance
attached to the Sun Ray enterprise server. If you type this command
without your smart card inserted, the new display setting will be
associated with the appliance and will remain in effect until you or
another user types the utxconfig command to change it.
• Ask your system administrator to change the display mode for all
appliances using the utxconfig command, which is fully
described in the Sun Ray system administration documentation.
Adjust the Brightness setting (see page en-13).
• Disconnect the keyboard or mouse, wait 15 seconds, then
reconnect.
• Disconnect the power cord, wait 15 seconds, then reconnect.
