On suspend, HAL passes VBE related quirk options to pmtools which crashes the proprietary NVidia driver

[Christian Kroll]

On suspend or hibernation, HAL passes VBE related "quirk options" to the pmtools (at least on my Dell Latitude D620). The pmtools on their part utilize the vbetool which isn't compatible with Nvidia's proprietary driver family (see chapter 18F in the drivers' README.txt.gz). On the aforementioned notebook, this causes a reboot as soon as you try to wake it up. There should be a way to instruct HAL to avoid passing those options to pmtools (ie. an option somewhere in /etc/default/$FILE).

After reading through the HAL specification, I noticed that there already is a way to instruct HAL not to pass VBE related options to the pm-utils. It can be done by setting the following properties to false:

sudo hal-set-property --udi /org/freedesktop/Hal/devices/computer --key power_management.quirk.vbemode_restore --bool false
sudo hal-set-property --udi /org/freedesktop/Hal/devices/computer --key power_management.quirk.vbestate_restore --bool false
sudo hal-set-property --udi /org/freedesktop/Hal/devices/computer --key power_management.quirk.vbe_post --bool false

This solved my power management issues in conjuction with the binary Nvidia driver.
I should have RTFM more carefully. Sorry for creating noise on the bug tracker.

Not really a bug. Problem solved via RTFM ;)
