i did this

mount -uw /

rm -r /system/library/extensions/Nvdaresman.kext
rm -r /system/library/extensions/geforce.kext

But I still have the problem when i reboot. I type in "reboot" after I type all the rm stuff. but it did not do nothing new reboot. maybe I'm doing something wrong.
what should it say between "rm -r /system/library/extensions/Nvdaresman.kext" "rm -r /system/library/extensions/geforce.kext"
