How to configure screen brightness when not using a laptop

rated 0 times [ 1] [ 0] / answers: 1 / hits: 496 / 2 Years ago, fri, april 29, 2022, 7:38:59

For a way too strange reason, my TV (which I'm using with a Dell Inspiron 1145 laptop running Ubuntu 11.10) does not allow me to do a fine-grained brightness configuration. Therefore, I'm looking for a way to configure this using Ubuntu by itself.

I've found a lot of articles/forum posts describing how to this, but all the solutions were related to notebooks.

Is there a way to configure my Tv/Monitor brightness without using its own controls?

I've used to use xgamma, from terminal:

myuser@mypc:~$ xgamma -gamma 0.8

I suppose the default gamma value is 1.0 (you can set greater values to brighter...). As far as I remember, the value is reset when you start a new session.
