first, sorry about my english, it's sucks

did anyone's ati fireGL 5250 working perfect?

Can open QE/CI ? and if it can work with external display?

my 5250 card can work with external display (mirror mode) when don't modify the driver

but when i modify the driver open the QE/CI, it' don't working anymore

PS:I forgot where I download the driver, it's a zip flie includ about 5 files(ATIRadeonX1000GA.plugin ATIRadeonX1000GLDriver.bundle ATIRadeonX1000VADriver.bundle ATIinject.kext ATIRadeonX1000.kext ), I use kext helper b7 to install them.

and i found if i plugin the External Monitor before turn on the power and use Fn+F7 chang display mode before the mac os booting,it's can use the External Monitor,but the screen is Vibration（do you know i mean? just like tv with bad singal), and in System Preference can't detect the External Monitor.

check out htis thread:
