I saw many saying that the latest version of Ubuntu 16.04 includes an opensource driver for ATI. I have an HP laptop with AMD 6770m + Intel HD 3000 hybrid graphics and wants to install Kubuntu on it. I created a bootable USB drive of Kubuntu 16.04 and booted from it just to check everything works perfectly (I don't want to install it separately and ruin bootloader as of now). But my laptop is getting too hot and the battery is not lasting for more than 30 mins. Also the brightness control is not working at all and it stays high always.
How can I get hybrid graphics on Kubuntu/Ubuntu working well? I am ready to turn off the ATI card since I am not going to play any games on Linux. I just need the Intel graphics + Cool Laptop + Good battery Life + Brightness control.
My BIOS setting for switchable graphics mode is FIXED. Do I need to change it to DYNAMIC?
UPDATE
I wasn't able to make things work in 16.04 so installed 14.04 LTS along with the AMD Catalyst driver. Now everything works perfectly fine. Below are the steps.
- Clean install Ubuntu 14.04 LTS
- Install the fglrx catalyst drivers using “Additional Drivers” window. This will enable us to switch graphics
- Restart Ubuntu
- FAN Noise Fix - Refer this url and install i8kutils
- Brightness Control - Check this link
This is the official documentation for AMD/Intel hybrid graphics
