How to rotate iBook G4 display?

Asked by rhodes54 (415points) September 13th, 2009

I have a 12” iBook G4 800mHz running Tiger and I need to figure out how to get it to display in portrait mode so that I can read sheet music from it.
Is there a terminal script or hack that will allow me do do this? And no, holding down the option key when opening Display Preferences doesn’t work. Or at least it doesn’t give me the option.

Thanks,

Why do you need to read it in portrait? I dont think standing the notebook on its side is best for it or the hard drive.

It’s for music gigs. I just had my MusicPad Pro stolen and I need something soon. It would only be that way for an hour at a time.

but i dont understand why you just cant open it and read it as it normally stands.

It won’t fit that way on an upright piano and the screen would be too small in landscape mode.

Grab a cheap external? It will give you that option.

edit :: I don’t think this can be done without fiddling with nvram. You don’t really want to do that. A few wrong keystrokes and your computer is fucked. And not in a way that you can just reload the OS. Like low-level fucked.

Needs to be somewhat portable. Want to do it with ONE device, if possible. I was really praying for the long-rumored Apple Tablet to come out last week, but no dice. The Kindle DX is too small and too slow for quick page turns and the Mimo usb-powered touchscreen is cool, but also too small. needs to be at least the size of paper. If I can get my iBook to rotate and then mod the display to fold 180 degrees, it would kinda sorta work.

Besides, I’m broke. A cheap external would almost buy me a used Tablet PC (all I need is Adobe Reader or something, not much processing power required.)

Ummm… Use at your own risk.

This is super risky. A restart would be required. I don’t really suggest changing that value to 90.

Thanks for the link, this isn’t my main computer so I’m not really worried. Can always reset PRAM and clean install if it doesn’t work. I’ll report the results

That is a plist file in here..

Luckily this isn’t as bad as mucking around in NVRAM. But it can still really fuck things up.

You would probably have to switch the height and width values too. Good luck. I would really suggest backing up that file before you mess with it.

Nuts, I can’t find Rotation in ANY of the strings. I’m in Omni Outliner and did a full search.

It is very possible that your video card doesn’t support rotation.

To get the editor in my pic you need Developer Tools installed. It is a free download from Apple but it is about 2Gigs.

I’m seeing all the other strings (in MY plist) in the plist pic that you posted, just not one for Rotation. You must be right about the card not supporting rotation.
