HP Remote Graphics 4.2.0 User's Guide Transparent Overlay Windows - Certain applications, primarily 3D applications, create windows in the overlay planes that entirely cover the main application windows that exist in the image planes. These overlay windows are primarily transparent and are used to contain text or other rendered images that should not be drawn into the image planes of the application. These overlay transparent windows are also called glass-bottom windows, as they can be used to "see into" the image planes. Applications that use glass-bottom windows do not currently share well with Remote Graphics Software. This problem is present only on HP-UX systems with graphics devices that 1) support overlay planes, 2) have the overlay planes enabled, and 3) run applications that create glass-bottom windows. As a work-around, to enable these applications to share properly over a Remote Graphics Software connection, the overlay planes can be disabled. Most applications will still run correctly with the overlays disabled. To disable the overlays, the X server's configuration file must be edited. The following table shows where the various configuration files exist: X server (platform) Xhp (PA HP-UX) Xf86 (PA HP-UX) Configuration File /etc/X11/X0screens /etc/X11/XF86Config The following X0screens entries will disable the overlays for an Xhp X server: Screen /dev/crt ScreenOptions SuppressPseudoColorOverlayVisual The following XF86Config entries will disable the overlays for an Xf86 X server running ATI Fire GL-UX graphics: Section "Device" Identifier "hp Fire GL-UX" Driver "firegl123" VendorName "hp" BoardName "Fire GL-UX" Card "Fire GL-UX" Option "Overlay" "false" Option .... other options .... #EndSection 7.

Transparent Overlay Windows - Certain applications, primarily 3D
applications, create windows in the overlay planes that entirely cover the
main application windows that exist in the image planes. These overlay
windows are primarily transparent and are used to contain text or other
rendered images that should not be drawn into the image planes of the
application. These overlay transparent windows are also called glass-bottom
windows, as they can be used to "see into" the image planes. Applications
that use glass-bottom windows do not currently share well with Remote
Graphics Software.
This problem is present only on HP-UX systems with graphics devices that 1)
support overlay planes, 2) have the overlay planes enabled, and 3) run
applications that create glass-bottom windows. As a work-around, to enable
these applications to share properly over a Remote Graphics Software
connection, the overlay planes can be disabled. Most applications will still run
correctly with the overlays disabled. To disable the overlays, the X server's
configuration file must be edited. The following table shows where the various
configuration files exist:
X server (platform)
Configuration File
Xhp (PA HP-UX)
/etc/X11/X0screens
Xf86 (PA HP-UX)
/etc/X11/XF86Config
The following X0screens entries will disable the overlays for an Xhp X server:

Remote Audio Issues (Linux only):
ALSA Quirks:
ALSA drivers can have problems mapping correct mixer channels to the
correct sliders. This means that on some more advanced or proprietary sound
hardware, the “Master Volume” control might incorrectly get mapped to the
“Headphones” slider or “Wave Mix” slider for example. The Receiver tries to
do its best to remedy these situations by adjusting common sliders like
“PCM,” “WAVE,” and “LINE” to appropriate levels, then attaching the volume
slider to “Master Volume” and the “Headphone” mixer channels. This should
