Adding my laptop into the mix.  Samsung QX410

obiwan ~ # dmidecode -s system-product-name && sudo dmidecode -s system-version
QX310/QX410/QX510/SF310/SF410/SF510

obiwan ~ #  lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | egrep 'VGA|3D'
00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) (prog-if 00 [VGA controller])
01:00.0 3D controller [0302]: nVidia Corporation GT218 [GeForce 310M] [10de:0a70] (rev a2)
obiwan ~ # 

obiwan ~/tmp/acpi_call # ./test_off.sh

Trying \_SB_.PCI0.OVGA.XTPX: failed
Trying \_SB.PCI0.P0P2.PEGP._OFF: works!
obiwan ~/tmp/acpi_call # 


one thing to note, the nVidia card shows up as a "3D controller", rather
than a "VGA controller".
