What's new in this kext? I have a ThinkPad T60 w/ dev ID 7149 and 1400 x1050 res and it's been working since 10.4 days

Do you know how to force the driver to only recognize 64MB vram vs 128 reported? I have CI/QE hardware support but get mouse tearing and some interlacing issues on the right side of my laptop screen (especially when gaming) and I have a suspicion that it is the Apple driver not supporting hypermemory and not correctly utilizing the 64MB of vram

Hi lostproc

Do you use also an kext injector (like NATIT_ATI_AUTO)? or use only the modified ATIRadeonX1000.kext ?

 

The main problem for this graphics card is the resolution recognition. tipically it is possible to have CI/QE enabled but it is possible to use only the vesa resolutions. So, in many cases, the biggest resolution is 1152x864 (at the boot you can see which resolutions your system support with the flag "?video")

Hi super_engine,

I use the native Apple ATIx1000 kext with IOPCIMatch on the ID. I have to fix the resolution to native panel level (1400x1050x32) via preferences in com.apple.Boot.plist. While this is good, I cannot switch resolutions without changing this file. I can see all of the modes the driver can do if I do a ?video at boot, including 1900x1200x32 which is supported via the external VGA port. What I've been trying to figure out is how to edit the ATIX1000 kext or plist and change the VRAM and see what happens. I've found numerous examples for nVidia cards, but not too many for ATI cards.
