[ubuntu-uk] Display blanking despite settings in gnome-power-manager and gnome-screensaver

[Iain Lane]

Hello all,

I switched to Gutsy from Windows a couple of months ago and have been
having a blast ever since. However, there is this one problem that I've
been having ever since the switch and it's pretty annoying. I'd been
living with it for a few weeks until I got a new laptop (eee pc),
installed Xubuntu on it and started seeing the exact same problem. Here
goes:

After exactly 10 minutes of idleness (no KB or mouse activity), the
screen will go blank (very irritating when watching movies as players do
not seem to be able to disable this, either). This is not a blank
screensaver, as I changed the saver to something else and still just get
a black screen. In gnome-power-manager (System -> Preferences -> Power
Management), all sliders are set to "Never". In gnome-screensaver
(System -> Preferences -> Screensaver), the "Regard the computer as idle
after" slider is at 40 minutes. Here's what I've tried and failed to do
so far - nothing made any difference at all:

* Disable DPMS in xorg.conf
* Remove gnome-screensaver
* Install xscreensaver instead
* Remove gnome-power-management (all per [1])

Anyone have any ideas what would be causing the screen to blank, and how
I can stop it? It seems counterintuitive that all of the applets to
manage this are being ignored.

Iain
