Hello,

I just got a PowerColor SCS3 HD6850 1GB Passiv.

 

Currently I have no Graphic card included in my dsdt.

My org.chameleon.boot.plist includes:

 

 

<key>GraphicsEnabler</key>

<string>y</string>

 

<key>AtiConfig</key>

<string>Bulrushes</string>

 

<key>AtiPorts</key>

<string>4</string>

 

The graphics work and the framebuffer gets loaded but the Mouse Cursor jumps around when moving.

 

Anyone like to help me to get this fixed , please?

Changing the framebuffer can affect the cursor and make it lag (don't ask me why - can't remember). Try getting rid of the ATIConfig key and adding:

UseAtiROM

Yes

 

Failing that try setting the framebuffer to Gibba / try all the ati 6xxx framebuffers. One should work, if your very unlucky and it doesn't work see here & good luck:

As a temporary measure disable graphics enabler (change it to no) and you should be working fine with no framebuffer (couple of games / dvd player won't work but thats it)
