Linux Connection Considerations; Full-Screen Crosshair Cursors; Gamma Correction On The Receiver; Black Or Blank Connection Session With The Linux Sender - HP Xw460c - ProLiant - Blade Workstation User Manual

The Remote Computer monitor blanking feature can be disabled by setting the following Sender property to 0
(false).
Rgsender.IsBlankScreenAndBlockInputEnabled
If this property is set to 0, monitor blanking will be disabled, meaning that a monitor connected to the Remote
Computer will display the user's desktop session. Furthermore, because monitor blanking is disabled, the warning
dialog shown in Figure 5-7 will not be displayed. For more details on this property, see Section 8-6-2,
general properties."

5-2 Linux connection considerations

5-2-1 Full-screen crosshair cursors

Certain applications that use large crosshair cursors (for example, PTC ICEM Surf uses a full-screen crosshair
cursor) will not display correctly on the Receiver. Full-screen crosshair cursors can be disabled by typing the
following in a terminal window:
/usr/contrib/bin/X11xprop -root -remove _SGI_CROSSHAIR_CURSOR
/usr/contrib/bin/X11xprop -root -remove _HP_CROSSHAIR_CURSOR
This will force the application to use an X cursor, which will display correctly on the Receiver.

5-2-2 Gamma correction on the Receiver

The color on a 3D application on the Sender can look incorrect when displayed on a Receiver. This is because the
gamma of the Local Computer monitor may not match the gamma of the Remote Computer monitor. To correct
this, any tool that will adjust the gamma for a display can be used. Some tools will adjust the gamma for the
entire monitor, while others will adjust the gamma on a per-window basis. Per-window tools that can be used to
adjust only the Receiver window will provide the best results.

5-2-3 Black or blank connection session with the Linux Sender

Connection to an X server that is configured with less than 24-bit or 32-bit default visuals (depending on the
graphics device) will cause the Linux Sender to generate a black or blank connection screen. For example, some
default installations may configure a 16-bit visual in /etc/X11/XF86Config after the installation. Reconfiguring the
X server to serve 24-bit (or 32-bit) default visuals, and restarting the X server will usually fix the black or blank
connection situation.
