hello, i need help
iam using 10.6.2 and my video card is gigabyte geforce 9400 gt 1mb dvi-i/vga/hdmi, and i have 2 monitors.
for the first time all working like a charm with this guide so i continue working with installing applications and updates.. while it updates iworks/ilife09 i go downstairs for launch.. when i back my snow gone sleep and i cannot make it awake... so i push power button and restart.. and then i got KP/message orders me to shutdown

i delete nvd* through leopard on another paritition and i can log in to snow leopard again.. with 2 monitors connected display running.. the only problem is QE/CI can't be enabled...
