I'm running Ubuntu 12.04 on a MacBook air - everything works fine, apart from the fact that the screen dims after 60 seconds of activity. Is there any way to stop this?
My computer is on mains power. If I stop using the machine, after 30 seconds the keyboard backlight turns off (that's fine). After a minute, the screen dims by about 50% - this is annoying, especially when watching a video or reading a long page of text.
My "brightness and lock" settings seem fine:
gsettings set org.gnome.settings-daemon.plugins.power idle-dim-time 600
But that doesn't make a difference - it still dims after 60 seconds, no matter what value I set it to.
I've also used
gconf-editor but I don't appear to have
I'm not using Unity - just the standard Gnome desktop.
Is there any way to change this behaviour? I never want my screen to dim. I'm quite happy controlling it manually with the F1 and F2 keys.
No - Caffeine doesn't work. The screen still dims.
No - changing the DPMS doesn't work.
No - Editing stuff in dconf doesn't work.
No - I don't have any other power manager software installed.
