NVidia GeForce 9500M GS

[dsTny]

Hey guys,

 

I successfully installed Yosemite on my Acer Aspire 7720G with Nvidia GeForce 9500M GS graphic card. I use Clover as boot loader. But I have several problems that caused that my system is a bit laggy especially using Mission Control and Application Windows. It seems that this is caused by two problems, one problem is that Clover does not recognise my graphic card correctly.

 

If I check inject Nvidia graphic card in Clover Configuration, Clover tells me that I have a GeForce 8600M GT. But injecting graphic card makes booting Yosemite constantly. If Clover should not inject my graphic card, it tells me correctly that I have a GeForce 9500M GS but often on startup Yosemite, the notebook restarts again. It seems that this happen in the step when normally the cursor appears in startup (so before the login window). I attached some pictures in System information with (not) injected graphic card and Chimera.

 

In Mavericks I used Chameleon/Chimera which always recognised with GraphicsEnabler=Yes my GeForce 9500M GS correctly. But to can download iMovie, I used Clover for some minutes with the result that it recognised the wrong 8600M GT and the download did not start because of a low power GPU.

Also it seems that not injected graphic card let Yosemite runs "smoother" (for example on scrolling through pages).

So what can I should I do? Inject graphic card or not? I prefer not, but my Yosemite should always start and not with luck. Could I fix this by using EFI or something else? Has someone Mavericks / Yosemite, uses Clover and has a GeForce 9500M GS and tell me how to get it correctly work (performance, battery safe on idle, QE/CI)?

 

Thank you very much for your help

 

/edit: I also attached my config.plist for Clover (with not injected Nvidia) and my dsdt, maybe you need this

The latest version of Chameleon will boot Yosemite so you are probably better off using that and getting the correct injection done. Also if you see "Error agpm controller unknown platform" then it means you are not getting proper power management for video card. You can at least in Mavericks edit the AppleGraphicsPowerManagement.kext and put your device ID in one of the macbook entries. I use MacBookPro6,1 for my smbios.plist on my 6920G which has the same video as yours the edited section looks like this.

You need to rebuild the caches or the change will not be seen and use MacBookPro6,1 as your device for this to work. And if you ever use it not connected to the Dell monitor then notice some annoying flickering when it changes power states you will need a VGA dummy plug which you plug in after booting but before the desktop loads. This seems to take care of it entirely if you have it plugged in at boot it disables the laptop screen on my machine at least that is why I say after boot plugin, no idea why the dummy plug does what it does but it works perfectly for this purpose.

Well.. I write it in this thread again The lags from Mission Control, Application windows and switching desktops seems to be gone if I disconnect my external monitor. Maybe the graphic card has to calculate so much that this causes the problem Have you got an external monitor connected, too and check whether you also have also lags?

 

I already changed the AppleGraphicsPowerManagement so this works

 

Actually I don't want to change back because I find Clover better. For example it doesn't need a FileNVRAM file to get iMessage working

 

I saw that the 8600M GT and the 9500M GS are similar - only the GPU memory clock of 9500M GS is 10% faster than the 8600M GT. So depending on what HWMonitor shows (GPUSensors), it seems that it runs on high speed permanently. So it seems that Clover uses the correct settings, right?

 

Thank you

When I have mine connected to external display (only tested the VGA) it disables the laptop screen so I have never seen any lag like you describe, is this connected via the dvi port yours has? If so try vga to see if it helps. The power is not working correctly for the video card that is what I get if it is not working full power all the time to it the frequency and voltage to is is supposed to drop when it is working like I see with the frequency here I don't get voltages displayed. On the iMessage I have nothing for the nvram installed and it was going to allow me to sign in on it both on Chameleon and the Clover boot stick I made to test booting with that.
