Dear Friends
I installed Ubuntu Netbook 10.10 in a partition alongside the provided
Windoze 7 in my new-last-week Samsung N145.
It's a lot easier to get into the system on my PC running Ubuntu 10.10.
As a relative newcomer to Linux I've been working at learning to use
Terminal and thought that was coming along nicely until I came upon my
current problem: I can't get the display to un-dim.
In Windoze mode the 'Fn' and 'up' or 'down' buttons control brightness
OK, but using these in Linux brings up an on-screen flickering slider
which doesn't work and necessitates an escape routine with the on-off
switch.
I got into 'Power Management Preferences' and the sliders there don't
work - the screen stays in power-saving rather-dim mode.
Clicked on 'Help' and there is lots of apparently useful stuff there and
a 'pinned post-it' : "Some sliders or option boxes may be disabled if
the GConf policy keys are not writable. This allows administrators to
lock down the actions that a user can select."
So I tried Terminal but can't find a way into GConf or
/app/gnome-power-manager/backlight/idle_brightness
When I first installed Linux on the machine, I am sure the brightness
was fine but I don't know what I did that changed it.
Any ideas on how I could control the display backlight please?
