Vgaswitceroo at startup

Postby Compiled on Mon Jan 21, 2013 12:52 pm

I've been trying for the past week to get my laptop running perfect in Mint 14 (Mate/Cinnamon), but I've run into an issue.

If i run
Code: Select all
echo OFF >> /sys/kernel/debug/vgaswitcheroo/switch
it disables the DIS gpu fine.
I then run
Code: Select all
sudo gedit /etc/rc.local
and add the above to it.

Apon rebooting I notice that the DIS gpu fan is still running, so i'll :
Code: Select all
sudo cat /sys/kernel/debug/vgaswitcheroo/switch
and notice that the IGD is PWR and the DIS is OFF (even though I know its physically on).
So I'll re-run switcheroo/switch and it turns off for about a minute then turns back on.

I'm at my wits end here.
I have a i7 3610QM + AMD Radeon 7970M.

I have also tried to install the lastest AMD drivers (13.1) and they work until I reboot (I can't find a how-to-install for noobs tutorial for this driver in Mint 14).
Is there anything I can do to disable to DIS automatically (i have a muxless machine here so BIOS switch is out of the question). I've tried using bash scripts but that doesn't work either unless I'm doing something wrong. I have currently uninstalled Mint 14 and I am just running Windows for the time being (I would like to dual boot).

Please help I was up until 4:30am trying to figure this out and I am at the point where I am just going to forget about *nix for a few years (until there is a stable automatic solution with software etc).
