Restore monitor res in command prom - bjames - 08-19-2018

Dam.. I set a monitor resolution that now cannot be displayed when the system boots into the login scree. The monitor is black and says “out of range”

Last time I had this issue was over 10 years ago. I can’t remember how to reset the resolution to 1280x1024_60. From the command prom within the “stop for maintenance” prom on startup.

Can someone tell me what to enter? Thanks

connect via serial console and log in as root.

Type the command: /usr/gfx/setmon -x 1280x1024_60

Can I enter the string from the maintenance prom at startup?

No, as IRIX has its own display settings which are independent from those in the PROM.

to the octane (octane is the system I need to rest the resolution) via the serial 1 ports.

I added the serial device “terminal” to port 1

Now what do I do to login to the octane from the o2 as root?

Re: Restore monitor res in command prom - bjames - 08-19-2018

I’m getting frustrated. I used the prom to login in as single user by typing “single” enter my root password and it takes me into the Unix shell. From there I type nvram monitor h and hit enter. Reboot and monitor stays black when the main login screen is supposed to display.

I was able to remote login as root to the octane using the serial connection, however if I access the tool chest, there is no display properties menus, and if I try to setmon from a shell, it says I can’t change the properties unless I’m resident on the octane - I interpret this as you can change display properties remotely.

I’m running Irix 6.5.8 on the octane

Is there a way I can delete all vfo files except the correct one or is there a editable file I can manually enter and save so when the machine boots up Irix (login screen) it will use the correct resolution.

Here are my notes:

console in or telnet/ssh in, su to root


oe whatever vfo you want to use, vfo's available are in





### or even better ###



Once in the prom, type: single
Press return.
You can then login in and use the command above

Is there a way I can use the original IRIX installation CDs to repair this? If so, what CD would the display properties be on? IRIX Foundation 1 or 2?

Re: Restore monitor res in command prom - Irinikus - 08-20-2018

If you log in via a serial (null modem) cable from a PC using PuTTY or hyperterminal you can easily fix this problem.

I think the settings are (9600 / 8-N-1) for the Octane and log in as root and type: (The mouse and keyboard must not be connected.)


You log in as root, by allowing IRIX to load, giving you a login prompt, then you simply type "root" and hit enter, you then type in the command given above.
