After installing nvidia-current driver with jokey my dell xps m1330 laptop won't compleetely shutdown. When i try to switch notebook off I finish with blank screen and hear hard drive heads parking. Then I need to poweroff notebook with long pressing the power button.
I've tried adding option acpi=force to kernel, but it didn't change anything.

I don't have shutdown problem after removing drivers.
Also with v.173 it shuts down normally, but I have problems with displaying sites content in web browser.
