GMA900 on laptop boots to blue screen

[kaiz3rsoze]

I have a GMA900 in a laptop and the display works fine without any of the patches, but only at 1024x768 and without QE. So I've tried both of the available patches to enable QE and higher resolutions for GMA900 under 10.4.8, the JaS patch and the B612 patch, and neither of them work. Both boot up to a light blue screen and nothing happens, with or without the VGA dongle trick. I'm assuming it might be because the patches are trying to set the resolution higher to what my laptop display supports (1280x800), but I don't know. Can anyone please offer some insight into this problem?

use my GMA900 Patch located in my sig.

to get past the blue screen you need either of the two tricks:

the two wire trick (i prefer this one)

or the

one wire trick

Thanks, it worked! One little thing though - is there any way to get the graphical startup screen working again? The patch turns on text output for some reason.

 

Also (just a minor inconvenience), is there any way to disable the second monitor so that the cursor doesn't go way off the right edge of the screen?

edit your com.apple.Boot.plist in /Library/Preferences/SystemConfiguration/

drag it to desktop then edit in text edit

change this:

<key>Kernel Flags</key>
<string>-v</string>

 

to this:

<key>Kernel Flags</key>
<string></string>

 

save and drag back into /Library/Preferences/SystemConfiguration/

authenticate and replace when prompted

repair permissions using disk utility.

you will notice the change when you reboot.

 

as for the mouse theres a monitor gathering trick:

(im just recalling from memory i might be wrong but hey its worth a shot, its found in the forums somewhere)

 

open display pref. pane in system preferences

click on the arrangement tab

click gather displays

set other display to same resolution as native, click apply

drag the menu bar to the monitor you just readjusted, click apply then gather again.

now drag the menu bar to the original monitor, click apply then gather again.

That how to do it I think

 

Or use the one wire trick and fiddle around wth the display pref.

I figured out you can also hold down command+option+o+f... and it boots to one screen instead of the wires..

 

now for the wire trick.. are you using specific wires or can i use a paperclip that is cut up??

This worked, but 1280x800 isn't an available resolution on the secondary monitor (1280x768 is), so it ends up giving me black bars on the top and bottom of the screen. Is there any way to add support for this resolution to the second monitor?

im not too sure other than tring to edit the com.apple.windowserver.plist

 

i dunno how or what to edit but it may be the trick.

Diabolik,

 

I´ve just installed your patch, but still getting blue stoped screen at my laptop Toshiba.

 

It has an Intel 915. I´m running the Jas Mac os 10.4.8.

 

So, how can I solve the blue screen at startup problem?

 

Thanks.

use either of the wire tricks in post #2

[edmund]

wire trick worked great for me
