Screen brightness settings for Mint 17
I have installed Mint 17 and now I cant even adjust the brighness on my laptop. It was an option in mint 16 under screen lock settings but its not available here. I cant find it in power management settings either. Laptop is Acer 5680. Anyone has any ideas?

Re: Screen brightness settings for Mint 17
On Cinnamon... menu/system settings/applet/Brightness
Put the applet on your panel and it should work.
I had a similar problem with the keys not working properly but now it's ok.
I turned off my nvidia card but I can not say whether it was that the solution

As mentioned earlier I did check but its not there. Mint 16 is so much better than mint 17. It used to boot faster too.

Run this command in terminal
(but before that your nvidia graphics driver should be installed and enabled; this will work only if your system works with nvidia graphics driver)
Now Run this
Under "Section "Screen", before "EndSection" add this line:
You can also install xbacklight using:
Place xbacklight command with your chosen settings in your "startup-applications" applet. command:
(this number 45 is the percentage of brightness, you can put any other number)
Reboot your system and Enjoy.
Code: Select all
sudo nvidia-xconfig
Now Run this
Code: Select all
sudo gedit /etc/X11/xorg.conf
So that section would look something like this (yours might not be exactly the same)Option "RegistryDwords" "EnableBrightnessControl=1"
Save file and now reboot your system and Enjoy.Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
EndSubSection
Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection
You can also install xbacklight using:
Code: Select all
sudo apt-get install xbacklight
xbacklight -set 45
(this number 45 is the percentage of brightness, you can put any other number)
Reboot your system and Enjoy.
Re: Screen brightness settings for Mint 17
I made the changes that you suggested, i.e.
sudo nvidia-xconfig
sudo gedit /etc/X11/xorg.conf
and added to the config file:
Option "RegistryDwords" "EnableBrightnessControl=1"
It dimmed the screen but it also changed the screen to 640x480 resolution. I can't get it back to 1024x768 which is my optimal. I'm a newbie to Linux Mint having just installed it on my ex-Windows PC. How can I revert back to the original config?

Re: Screen brightness settings for Mint 17
You might have to change the video driver to use the x-server video nuveau driver...
I have an nvidia card and half of the Cinnamon controls won't work using the 'recommended' driver, so I had to go back to generic one to get them to work.
All I can tell is, if you use that driver, everything should work... including the brightness applet. (because that's what I have to use now since they got rid of the 'brightness and lock')

Re: Screen brightness settings for Mint 17
I looked and looked, tried and tried looking to adjust brightness for both screen and keyboard, oddly not found in SETTINGS. Why I don't know. BUT I was able to adjust by clicking on the battery icon(lower right hand of screen), and there pops up a sliding adjustment for both screen and keyboard. I have mint 17 Cinnamon.
Re: Screen brightness settings for Mint 17
If you can adjust brightness from the panel, you should find the setting also in the power settings.

delete the file /etc/x!!/xorg.conf and reboot, it will restore.Ip Man wrote:I made the changes that you suggested, i.e.

Re: Screen brightness settings for Mint 17
Go to menu -> power managment.
Use terminal to download xbacklight, e.g.
Type xbacklight and see available commands. I used xbacklight -inc 10 a few times till reached desired brightness.

Re: Screen brightness settings for Mint 17
I am on Linux Mint 17.3 Cinnamon. My graphics card is: Advanced Micro Devices, Inc. [AMD/ATI] Thames [Radeon HD 7550M/7570M/7650M]
I am not using the proprietary drivers, just the default open source ones because the proprietary ones are very limited in features and give me way more problems even though I do get better gaming performance out of the proprietary drivers.
The Brightness applet does not work for me. When I change the brightness nothing happens. The xbacklight program does not help me either. When I set the brightness nothing happens.
