HP-UX Desktop Troubleshooting Guide

7.2.1.2 For Xhp
1. Check if the legacy HP device (typically HP VISUALIZE-FXE card(s)) are available
on the system with the following command:
# ioscan -kd graph3
This command lists the legacy graphics device(s) connected to the system. If there
is no legacy card connected to the system then you cannot run Xhp on the system
unless you run this as a print server. For more information on running Xhp as
print server, see GAG.
2. If the legacy graphics device is available on the system and Xhp continues to fail
because of an error in graphics card, then you may need to check the existence of
the “/dev/crt*” device files by running:
# ll /dev/crt*
Also verify that these are character special files and not ordinary files. If this check
fails then
• Delete the all the device file using the following command:
#rm –rf /dev/crt*
• Reboot the system (and restart X manually if it does not restart automatically).
This will automatically create the device files.
7.2.2 Error due to Input Devices
The Xserver on HP-UX typically supports two input devices - keyboard and mouse.
7.2.2.1 Mouse as input device
Xserver may fail to start due to any one of the following reasons:
• Improper physical connection of mouse with the system.
• Device drivers not available to support the hardware
• Incorrect input device entries in the X start-up files.
7.2.2.1.1 Physical connection of the mouse
To find the existence of the pointer device on the system check the output of the
following command:
# ioscan –k | grep –i mouse
In some cases, physical connection of the mouse with the system is required for X to
start. The following table provides the information regarding the mouse connection
required on various OS versions.
