Installed 10.4.7, and it works swimmingly (after some tweaking). I'm using an italian PC keyboard and even with the correct italian OSX profile, a lot of keys are displaced. How can I fix it?

 

Also, I can't choose 1152x864 screen resolution, only 1024 and 1280. Is there some file I can edit for that?

 

thanks :D

no idea about the keyboard, but if you have a Nvidia graphics card, then go here:

I'm pretty sure there are some drivers for ATI cards as well.

Some people find they need to install the GMA900 package under Customize in order for GMA950 video to work properly. You should be able to boot the DVD, go to Customize and select ONLY the GMA900 package. The Install button will now say Update. Click it.

 

Warning, if the GMA900 package doesn't help, it will probably hurt and you will probably be reinstalling.

If the drivers and acceleration were working fine, you would be able to select the resolutions in the System Preferences.

 

Since you cannot, the drivers are not working and you are in VESA mode. The available resolutions are read from the card, not a plist.

 

You can try to set an arbitrary resolution at boot and if you happen to find one that works, you can add that to a boot.plist to force the video card to that resolution.

 

During boot, you need to get to a command prompt. When you boot, the screen first turns black and then grey with a spinning icon.

 

As soon as the screen turns black, start tapping the F8 key quickly and repeatedly until a command prompt appears.

 

Typing ?video will display a list of available resolutions.

 

Typing the following at the command prompt will force the resolution at boot. However, if the video card and monitor cannot sync, you will end up with a black screen.

 

At the prompt, type: "Graphics Mode" = "1280x1024"

You must use the quotes and you can replace the 1280x1024 with a value you found from ?video.

 

Once you find an acceptable resolution, you can add it to the boot plist file:

Edit the file: /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

Add the following to the file:

<key>Graphics Mode</key>

<string>1280x1024</string> (or whatever resolution you select)

Did some experimenting. ?video at boot does not show 1152x864 as a valid resolution. Only 1024x768 and 1280x1024, plus higher and lower ones. But in OSX (system prefs/displays) I have a lot of wacky resolutions available - like 1024x497 or 1280x622 (wtf?) and they actually work. editing the boot plist does not change anything.

The resolutions in System Preferences are determined from the video card and the monitor. There are no resolution selections pre-stored in OSX anywhere.
