2.8 Screen Issues

2.8.1 Sun Ray Session Uses Default Display of 640x480 When Monitor is Connected to DVI-2

When a monitor is connected to DVI-2 on a Sun Ray 2FS Client or Sun Ray 3 Plus Client and there is no monitor connected to DVI-1, the Sun Ray session uses the default display of 640x480.

Workaround: When connecting a single monitor to a Sun Ray 2FS Client or Sun Ray 3 Plus Client, connect it to the DVI-1 port.

2.8.2 GNOME May Crash After Hotdesking When Dynamic Session Resizing Enabled (Oracle Linux 5)

When hotdesking an Oracle Linux 5 desktop with dynamic session resizing enabled, GNOME may crash. If GNOME crashes, all the windows are terminated and a new session is created. This issue does not affect desktop resizing when using kiosk mode.

Workaround: Disable dynamic session resizing.

2.8.3 Screen Flickers on Sun Ray 3 and Sun Ray 3i Clients When Viewing Configuration GUI

When a Sun Ray 3 or Sun Ray 3i Client is at full resolution (1920x1200 or 1920x1080), the screen may flicker when the Configuration GUI is displayed with STOP-M.

2.8.4 No Screen Lock For Second Oracle Linux Session

A user who creates two Oracle Linux sessions cannot create a screen lock for the second session. When Sun Ray Software needs to lock the screen, it uses xlock for the second session. When the user tries to lock the screen from the menu, nothing happens.

Workaround: Start a screensaver daemon for the second session manually, which enables screen locking and stops Sun Ray Software from using xlock.
