determining swap performance

The DBE API does not allow users to determine if double-buffering in a
visual is through software or hardware. However, the API does provide a
way to determine relative swapping performance on a per-visual basis.
The XdbeScreenVisualInfo() function returns information about the
swapping performance levels for the double-buffering visuals on a
display. A visual with a higher performance level is likely to have better
double-buffer graphics performance than a visual with a lower
performance level. Nothing can be deduced from any of the following: the
magnitude of the difference of two performance levels, a performance
level in isolation, or comparing performance levels from different servers.
For more information, refer to the DBE man page on
XdbeScreenVisualInfo().

supported devices

The X Server supports DBE on the following devices:
HP VISUALIZE-FX5 and FX10
HP VISUALIZE-FXE

display power management signaling (DPMS)

Monitors constitute a large percentage of the power used by a
workstation even when not actively in use (i.e., during screen blanking).
In order to reduce the power consumption, the Video Electronic
Standards Association (VESA) has defined a Display Power Management
Signaling (DPMS) standard which can be used to greatly reduce the
amount of power being used by a monitor during screen blanking.
The X Server features the ability to make use of DPMS on the following
graphics devices:
HP VISUALIZE-FX5 and FX10
HP VISUALIZE-FXE
configuring X Windows on HP-UX (HP Visualize graphics cards)
X Server configuration
