[ltp] Screen doesn't blank properly on R50 with ACPI.

[Luke Yelavich]

Hi all

Whenever it comes time for the screen to blank on my R50, instead of the
backlight turning off, the screen fills almost entirely with white. This goes
away when a key is pressed however.

I am running Slackware 10.0, with ACPI. This happens with both a 2.4.26, and a
2.6.7 kernel.

Apm is fine, but I would rather not use APM, as once my fan turns on, it stays
on, and this is my only problem with ACPI

The command I use to set the screen blanking is the following:

setterm -blank 15 -powersave powerdown -powerdown 60

I have tried setting the powerdown and blanking to the same, with no difference.

This only occurs on the console. I haven't tried setting anything up in X yet.
An external monitor works as expected.

Suggestions welcome.

Luke
