Comment 47 for bug 752542

Hello,

I'm having difficulty in switching from my on-board Intel graphics
card to my nVidia card. I believe I need to use some ACPI commands to
perform such switch.

I've used the acpi_call 'test.sh' script - but never see the 'It
works' message. I also cannot see any /sys/kernel/debug/switcheroo or
similar controls despite debugfs being mounted and modeset=1 being set
on the kernel command line.

I've attached a dsl file describing my ACPI configuration. Please find
below additional information about my hardware.

Can someone point me in the right direction as to how I can make
progress on this? Or even some pointers on how to interpret my dsl
file.

amurray@summer:~/acpi_call$ sudo dmidecode -s system-product-name
Dell System Vostro 3750
amurray@summer:~/acpi_call$ sudo dmidecode -s system-version
