-------- Original Message -------- Subject: Netbook LCD brightness Date: Sun, 03 Apr 2011 17:44:36 +0100 From: Tony Wood <tonywoo...@ntlworld.com> To: Hampshire@mailman.lug.org.uk 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? Tony Wood Dear All BINGO! It's OK now: it just needed an excursion into the BIOS. d:-) Sorry to trouble you. Thank you.
