Title: What do I do if I set the resolution too high?

Hi all,

I am using NeXTSTEP 3.3 on VMWare and set the screen resolution too high. Now it's in an endless boot cycle. I spent a lot of time on that image and would like to recover, but in single user mode I have not been able to find the file that contains screen resolution configuration. Could someone please point me in the right direction?

Thanks!

Here are some tips.  This is mostly from memory on Openstep, so keep good notes and make a copy of any file that you edit in case you have to backtrack. 

First Method - Assumes you changed the display driver/device to something other than VGA.

#cd /private/Devices
#cd System.Config
#cp Instance0.table  Instance0.table.oldversion

edit Instance0.table with a text editor and change the line "Active Drivers". Replace <driver with bad settings> to VGA. 


Second method - You can edit the video driver/device to change the settings back to more reasonable ones. 

#cd /private/Devices
#cd <your video driver>.Config
#cp Instance0.table  Instance0.table.oldversion
#cp Default.table Instance0.table

           Alternately, you could edit Instance0.table but that requires more detailed information on the settings/syntax for this file.


When done  #sync and #shutdown -r now.

Good luck.

I seem to recall also that there is a boot option config=default?
