AIX Version 4.3 Commands Reference, Volume 1

chdisp Command


The chdisp command changes the default display being used by the Low Function Terminal Subsystem.


chdisp { -d DeviceName | -p DeviceName


The chdisp command changes the display used by the low function terminal (LFT) subsystem.

To generate a list of available displays and their respective display identifiers and descriptions, use the lsdisp command. For an example of the listing displayed, see the lsdisp command example listing.

Note: The chdisp command can be used only on an LFT.

Alternatively, you can use the Web-based System Manager Devices application (wsm devices fast path) to change device characteristics. You could also use the System Management Interface Tool (SMIT) smit chdisp fast path to run this command for certain devices.


-d DeviceName Changes the default display currently being used by the LFT. This change is temporary resulting in the default display reverting back to the original display when the system is rebooted.
-p DeviceName Changes the default display to the specified display at the next reboot. This stays in effect until the user changes the default display again. The user must have superuser access to use this option.


  1. To temporarily change the default display to a display with a device name ppr0, enter:
    chdisp -d ppr0
  2. To permanently change the default display beginning with the next reboot to a display with the device name gda1, enter:
    chdisp -p gda1


/bin/chdisp Contains the chdisp command.
