Can't log display error

[polloarena]

Hi, after installing Tiger in my G3 500 dual to log I need to boot in a safe mode all the time else:

I use a Sharp Flat Panel Monitor and somehow my system assumes I have 2 monitors and places the Sharp "display" on the right side. I have a grey screen in front of me where I can see the mouse pointer if I move the mouse. If I move the mouse all the way to the right it vanishes and this looks very much as if the during the bootstrap process the system understand there are 2 Monitors connected to the machine.

If I start the Mac in safe mode (with the Shift key down) everything is fine.

How can I start the computer normally and get the screen without pressing the shift key?

Or is there a way to edit the boot-loader file sequence? and if yes how to do so? I am not very familiar with the terminal and in any case I need to use it starting up in the safe mode else I have nothing to work with

Regards

'G3 500 dual' - Apple never made such a model. How did you do it?

When you booted the G3 500 dual (?) in 'safe' mode, have you launched (run, opened) 'System Preferences' and selected the 'Displays' utility?

If you do such, do you see something like 'this'? If so, then drag the menu bar from the current (ghost) display, to the 'other' (Sharp Flat Panel) display. You should now see a menu bar on the 'Sharp Flat Panel Monitor'. If so, reboot your Mac (in non-safe mode).

If you now can boot, normally, and have the menu bar present, revisit 'System Preferences' 'Displays' utility, and try to determine and eliminate the ghost monitor.

Unfortunately this option only works with two monitors attached and I only have one.

For some crazy reason my system rewcognizes I have only one Monitor when I boot in safe mode.

In safe mode calling the Display system prefs shows the only monitor I have: I have no ways to "bless" it (don't know if this is the proper way to say so, but I hope you understand what I mean) as I have just one ...

I am trying to figure out ways to use the terminal but I am not familiar with it
