Trying to enable hybrid graphics on a HP Pavilion DV7-4142eg:
dmidecode -s system-product-name; dmidecode -s system-version HP Pavilion dv7 Notebook PC 058B110000242B10000020100
lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA 01:05.0 VGA compatible controller [0300]: ATI Technologies Inc M880G [Mobility Radeon HD 4200] [1002:9712] (prog-if 00 [VGA controller]) 02:00.0 VGA compatible controller [0300]: ATI Technologies Inc Manhattan [Mobility Radeon HD 5000 Series] [1002:68e0] (prog-if 00 [VGA controller])
Using a self-compiled kernel 2.6.36.2, the dmesg says
VGA switcheroo: detected switching method \_SB_.PCI0.AGP_.VGA_.ATPX handle
but using the "acpi call" method results in kernel Oops
Please find attached the DSDT table.
By the way, it is not possible to change the display brightness via the keyboard buttons for this purpose.
