OEM Technical Manual • May 1999
Once you enter this command, the system will use this display mode when Common
Desktop Environment (CDE) comes up on the monitor. If you enter this command
within a GUI, you must log out and then log back in before it takes effect.
To check which display modes are currently supported by your graphics controller
card, enter:
machine_name% m64config -dev /dev/fb -res \?<cr>
or
machine_name% m64config -dev /dev/fb -prconf \?<cr>
Once you enter the above command, a list will appear. Display modes followed by a
’[2]’ suffix are not currently supported. The ’[3]’ suffix indicates the current screen
resolution.
Note that you can get information on m64config by entering:
machine_name% man m64config<cr>
■ To recover when the display becomes unviewable
The display may become unviewable as you move between GUI and console modes:
■ If you exit the GUI and the console mode display is unviewable, try entering:
machine_name% set-default output-device<cr>
■ Entering the GUI from console mode is unlikely to be a problem unless
m64config has been used to set a GUI display mode not supported by the
current monitor. In this event, you can use rlogin to access the system over the
net, or reboot the system with a terminal or workstation, and then use the
m64config command to set a supported display mode. When you enter CDE
again, it will be at the new display mode setting.
■ If the screen becomes unviewable and you are unable to perform a remote login:
1. Reboot the system or if necessary, cycle power on the system.
2. Stop the boot process as the boot banner appears by holding down the Stop key
and then press A (use the Control and Break keys on PS/2 keyboards).
3. Type boot -s<cr> (for boot into system administration/maintenance mode).
4. Use the root password to enter the system administration/maintenance mode.
5. Use the m64config command to change the display mode setting (see “Set the
Display Mode for OpenWindows or CDE” on page G-5).
6. Either use reboot<
cr> to restart the system, or type exit<cr> to exit system
administration/maintenance mode.
