Hi, i recently bought a sony-vaio laptop.
It has hybrid graphics intel/nvidia

$ sudo dmidecode -s system-product-name
VPCZ11X9E
$ sudo dmidecode -s system-version
J0044RC7
$ sudo lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' |
grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation Arrandale
Integrated Graphics Controller [8086:0046] (rev 02) (prog-if 00 [VGA
controller])
01:00.0 VGA compatible controller [0300]: nVidia Corporation Device
[10de:0a2b] (rev a2) (prog-if 00 [VGA controller])

I have switcheroo enable in kernel (from git)

$ dmesg | grep switch
[    9.136240] VGA switcheroo: detected DSM switching method
\_SB_.PCI0.P0P2.DGPU._DSM handle

but no files for switching under /sys/kernel/debug (which is where I
have mounted debugfs.)
$ ls /sys/kernel/debug/
acpi  apei  bdi  bluetooth  boot_params  dri  hid  ieee80211  kprobes
mce  mmc0  mmc1  tracing  usb  x86


Any advice? I just need to enable the nvidia card, cause KMS on intel
gives me a black screen.

Thanks,
