Increase time before screen dimming - Mint 12

[humturtle39]

I get the impression i'm missing something stupidly obvious, but my laptop screen dims after 10 seconds on battery power and I can't find an option within GNOME to increase that time?
Found an option to toggle screen dimming on/off, but I still want the screen to dim, just not after 10 seconds.

Help much appreciated.

Check under "Power" and "Screen" entries under settings. Don't have Mint on laptop, so I can't be more precise.

I didn't find anything in those two wich would increase/decrease screen dimming...

Go to system settings/screen (lock), disable 'dim screen'. No idea how you can increase the time of 10 seconds default.

Or in a terminal, start 'gnome-control-center screen'

Try the following command in the terminal:

Code: Select all

gsettings set org.gnome.settings-daemon.plugins.power idle-dim-time 60

Unfortunately, this no longer works with Mint 13: "No such schema 'org.gnome.settings-daemon.plugins.power'"

Anybody know how to change the idle time in Mint 13?

TIA

I forgot to mention that I'm running the Mate edition of Maya.

Anyway, I found the solution:

In your home directory ~/.mateconf/apps/mate-power-manager/backlight/%mateconf.xml insert the following entry:

<entry name="idle_dim_time" mtime="xxxxxxx" type="int" value="300"/>

Set "xxxxx" to the same mtime as the other entries in the file. The time is in seconds, so my setting of "300" equates to 5 minutes.

Logout and login again.

Heres what to do: Go to:
Menu
Control Centre (this is under Systems)
Screen Saver
all screen saver tools are there, you can adjust the time out up to 2 hours or take the dimmer off altogether.

In MATE you can start Mint → System Tools → Configuration Editor or

Code: Select all

mateconf-editor

from command line) and go to

Code: Select all

/apps/mate-power-manager/backlight/

There you'll find

Code: Select all

idle_dim_time

setting (in seconds) – thi is the setting. Also you can set

Code: Select all

idle_brightness

to dim more or less.

I had the same issue (with Linux Mint 14) and the method posted by Maug Lee worked perfectly, thanks!

The solution posted by Maug Lee didn't work for me, perhaps because I didn't have exactly the same problem.

I had dual monitors set to a solid blue background. The right-side monitor would dim almost immediately after booting Mint 13 Mate. The left monitor didn't dim. The right monitor was set as the default monitor.

When I switched to one of the supplied desktop background images, the problem went away - no more immediate dimming. But would greatly prefer a solid background.

A similar method to that posted by Maug Lee also works in Mint 17 Mate, only the appropriate setting can be found by opening

Code: Select all

 dconf-editor 

from the terminal and going to

Code: Select all

 /org/mate/powermanager/idle-dim-time 

.
