Hi to all,
I'm new to archlinux, but I've been attracted by the rollin release scheme and I'm trying to understand better how linux works, so I've decided to try it.
I've managed to install and setup everything, but the discrete graphic turn off module. When i was using ubuntu I had found a module (lenovo_acpi.c) that was written just to turn off the discrete ATI card using ACPI and it gives to me a couple of hours more of battery, but with archlinux it seems to not work. I've managed to build it, to modprobe it but with the lsmod the two graphics card are still there and the power consumption is still high.
Is there any known issue? Someone knows any difference with ubuntu/suse/fedora that prevents this module to work with archlinux?
Thanks,
GortiZ

lenovo_acpi works fine under Archlinux. You will have to install the kernel header files to compile it:
sudo pacman -S kernel26-headers
I usually reach about 8W power consumption (check with powertop).

Hey,
is lenovo_acpi still working with current kernel (3.6.3-1-ARCH) ? I just switched from gentoo to ubuntu to archlinux because I couldn't turn my ati card off anywhere..
I also tried this switching:
https://wiki.archlinux.org/index.php/Ac … e_Graphics
which reduces the heat a little and gives me some extra hours.. but it's not that good as lenovo_acpi..
Is there any other way to turn the graphics card off? Or is there any way to get lenovo_acpi to work again?
greetings
