Changing display resolution

[mike200015]

Hi,

 

I have an ATI Radeon 9200 video card, and i currently have only 1 resolution in the display settings.. 1024x768, and was wondering how to change it.. i looked in the Tips and Tricks thing and it says to type in '-x "Graphics Mode" =" ....' on boot, but when i boot into OS X i dont get the option anywhere to type anything in. I have JaS 10.4.6 installed.

 

Anyone know how to get into the thing when i load OS X to type the graphics mode stuff in?

 

 

 

Thanx,

 

Mike

Press F8 key before boot. If you want to change your resolution permanently edit the com.apple.Boot.plist and add this two lines :

 

<key>Graphics Mode</key>

<string>1280x1024x32</string>

 

You'll find this file in /Library/Preferences/SystemConfiguration/

it didnt work. When i load mac os x.. it goes to a black screen that says loading Darwin x86 for a sec, and then goes to the grey apple load screen, and then loads os x. I think theres supposed to be another screen at boot where i can press F8, but there isnt??

Hit F8 when you see the "loading Darwin" screen the first time.

 

If that doesn't work, do the following in the Terminal (ripped from this thread, but put in reverse):

 

sudo -s
cd /Library/Preferences/SystemConfiguration/
nano -w com.apple.Boot.plist

Enter your password when prompted.

 

To give you boot options:

 

Now look at your file. In between the <dict> and the </dict> brackets, make sure you have the following key: (Note: other keys will also be present)

<key>Timeout</key>
<string>10</string>

If that doesn't exist, or has a different value, modify the file so that it exists now.

 

Now make sure the following key is set this way or nonexistent:

<key>Quiet Boot</key>
<string>No</string>

 

To set your resolution:

 

If you already know what resolution you want your computer to run at and don't want to type it in as OS X is starting up, add the following:

<key>Graphics Mode</key>
<string>1280x1024x32</string>

Make sure you replace 1280x1024 with the desired resolution.

 

After you're done making all these changes, Ctrl-O to save, Ctrl-X to exit.

 

Now restart your system, and cross your fingers.

 

Edit: Avoiding nano

 

By typing this into Terminal, you can edit com.apple.Boot.plist in TextEdit and save your changes:

sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit

Enter your password when prompted.

 

Now, navigate to /Library/Preferences/SystemConfiguration, and then drag com.apple.Boot.plist into the open TextEdit on the dock. Your Terminal window will not respond again until you have exited TextEdit.
