Support Gnome 3.18

[Svarozic]

Hi I can not install extension on my Artengos with Gnome 3.18.3, can you support it ?

Hi. I don't currently have access to a machine that has both gnome 3.18 and a radeon GPU. However, until I do, you can try to edit the file metadata.json and replace '3.16' with '3.18'. Please let me know if this works for you.

It seems that it works will metadata.json modification. Thanks for help

Please don't close the issue yet. It's a reminder that I have to handle this.

Hi i have installed this extension successfully and it is showing "currently on default profile". But even after clicking on "set profile to 'low' " or any other option it is not changing that status. Still showing "currently on default profile". Is everything alright or is it a bug ? My machine's specifications are as below :
OS : Fedora 22 (GNOME 3.16.2)
Graphics : AMD Radeon HD 7670m

@shubhampatil17 that is most likely because you are already using the new DPM power management.
When I wrote this extension, power management for radeon cards was really very poor where you could only choose one of three states (low, mid and high), with a few exceptions.
Nowadays radoen cards use a much more complete power management solution, called DPM, where you can choose not only the power profile, but also the card frequency.
I have started working on something like this before my laptop with a radeon card died on me, here (Yes, it's in a separate branch).
In order to use the DPM settings, you should try that branch instead.
Also, keep in mind that both programs (the extension and the systray one) only work with the OSS driver, and not with catalyst.

You can also try this fork of the extension:
https://github.com/lalmeras/shell-extension-radeon-power-profile-manager
It should support DPM, but I haven't really looked closely at it.
