gmax3100 not working

[alebb]

Hello everybody. I have a problem with my graphics card.

First i wanna say i ve already tried searching on google, on this forum ecc, but none tutorial,old topics worked with me. 

The problem is that i can use only 1024x758 resolution. But it is supposed to be much more. 

I ve tried setting 32bit, installing a lots of next ecc. but nothing.

Can someone help me? Thanks

Hi again,my friend

To run Lion on to 32 bit mode you need to write on Extra/com.apple.Boot.plist(etc:org.chameleon.Boot.plist)

 for 32 bit mode,write this one(red font)

    <key>DSDT</key>
    <string>/Extra/DSDT.aml</string>
    <key>EthernetBuiltIn</key>
    <string>Yes</string>

    <key>GeneratePStates</key>

i've tried but nothing, alway 1024x768. I ve seen into the next you gave me and the ID dev is 2a02 but mine is 2a42. I checked on windows with everest my graphics card. Everest says it's gma4500mhd but Lion says its gmax3100.

4500 or x3100? http://laptops-specs.blogspot.com/2011/02/acer-travelmate-5335-specifications.html

Anyway when i found out my graphics card is a gma4500 i follow the steps of this http://www.osx86.net/files/file/1889-intel-gma-4500mhd/ 

but when i reboot the apple logo appear the system loads but then the screen gets dark. The SO is working but the screen no.

Anyway should i star another topics abaut gma4500 or can i continue with this?
