ATI Radeon HD7000 Series (Laptop) - Switch Mode Between ATI & Intel Integrated GPU. Stuck on Boot Screen On Intel GPU Selection Mode
- by Monkey Drone
Laptop Specs:
HP Pavilion G6-2020SE
GPUs
1) ATI HD7000 Series
2) Intel Integrated
OS Installed:
x) Ubuntu 12.04 (64 bit)
i) ATI Graphics Card Drivers Installed From AMD website.
Note: Graphics Card Drivers are Working Fine in 3D Mode. It runs a little Hot as it should since its a GPU.
Observation) AMD Catalyst Control Centre Lets me Choose If I want to run the system in HIGH-END (ATI GPU)
OR
Intel Integrated (Better battery life)
While I am on High End GPU Choice, Ubuntu works fine.
Problem) But when I switch to Intel Mode in the AMD CCC and reboot the Machine. Ubuntu goes into 'Low Graphics Mode'. The problem is not that it goes into low graphics mode, it is completely expected since I am no longer using the ATI GPU but the integrated Intel GPU. Problem starts with the 'Selection' of the options.
During that screen, I have no mouse on the screen (even tried plugging in an external USB mouse) & No Keyboard functionality. Thus I am left completely disabled to choose any option and load into Ubuntu.
The Only thing I can do is switch to a terminal and enable ATI GPU through command-line and Ubuntu works Fine again.
Is it a bug that there is no mouse/keyboard available to me during the startup of Ubuntu when its launched in Low-Graphics Mode?
Any suggestions on how to pass through that? My palms are sweating as I write this down because the ATI GPU is really heating up my laptop. I dont want to boot into Windows or keep it around any longer than necessary. Please advise with help and directions.
Sincerely,
MonkeyD
Edit1: The Answer by Celso has helped me switch to Intel, thus giving me sufficient battery power. Kudos to Celso. Now I can at least use my laptop for the time being without having it burn hair off my skin.
I am still looking for answer to my original question of, 'why is lightdm not working properly when I switch to Intel GPU using ATI HD7000 series official drivers provided by AMD'.
