brightness and screen resolution


How may I lower the screen brightness and contrast in Ubuntu? In Windows, I use the Intel Graphics Extreme 2, but there isn't one for Linux, as Intel says Linux distros have graphics driver by themselves.

So what to do? I cannot use the Monitor's panel and I don't want to because it is almost broken and its time consuming. And I don't want it to change when I boot Windows.

And when I change my screen resolution to 1024 x 768, my display turns off and nothing happens.

If your display turns off almost certainly your card is not set up correctly. Have you gone to your display settings in Ubuntu and checked if it is using the correct driver?

Where is the display settings in Ubuntu? How to check if it is using the correct driver?

When I go to the System > Monitor Resolution Settings, below the Mirror Screens check there is written Unknown, the resolution is 1152 x 864. In Windows the resolution 1024 x 768 is working fine.


Can I just know how to adjust my brightness?

It's not a straight forward process adjusting your brightness from command line. Post the contents of your /etc/X11/xorg.conf file, let see if we can get 1024x768 for you. Or buy yourself an anti-glare filter for your screen seeing as you don't want to use the controls.

I changed my resolution to 1024 x 768, my display turned off, when I restarted my PC, the resolution has changed?

Now I want to adjust the brightness, contrast and gamma. The monitor is burning my eyes, please help

And you didn't told me if I'm using the correct driver.

BTW, it would be cool if I able to know why the display is turning off when I change the resolution.

Doesn't matters if it is a straightforward method or not, just want the task to be done, cuz the monitor is burning my eyes

Is this the entire contents of your xorg.conf? There's no reference to your monitor or it's capabilities and no reference to your graphics card driver. I would start by going to System--> Administration and run the Hardware Drivers app. If that doesn't detect, download and install the correct driver for your graphics card, let us know in this thread.

Open your Synaptics Package Manager and check if you have the xserver-xorg-video-intel package installed. If not install it. Just type intel in the search box to filter the list of packages.

No change, it's still the same. The xorg.conf is same, the screen resolution when changed turns off the display.
