I'm running Dell XPS L501X. I'm able to disable the Nvidia card with the
acpi_call module, but I cannot switch to the nvidia card with either the
noveau or the nvidia proprietary drivers.

$ sudo dmidecode -s system-product-name && sudo dmidecode -s system-version
XPS L501X  
A06
$ lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 18) (prog-if 00 [VGA controller])
02:00.0 VGA compatible controller [0300]: nVidia Corporation Device [10de:0df1] (rev ff) (prog-if ff)
