thats my first post i have an old imac G4 with 700 mhz. i installed leopard on it with leopard asset it all went well except one think, screen becomes dark after wake from sleep. i googled around and discovered was a bug from leopard with the geforce 2mx kexts. i also saw i have to replace them with the tiger kexts, but im afraid of loosing quartz extreme. anyone has come across this problem? is there any solution? or replacing the kext will work?
