Hi, today I bought this nice piece of hardware. I didn't get chance to windows boot up first time
I installed latest Ubuntu 12.10 Beta 2 abd try install bumblee. Seems to works. But seems to nvidia card is always on. There is some problem with bbswitch module.
1) check the status
bumblebeed: Unable to disable discrete card.
2) trying disable card
root@xps:# optirun --status
Bumblebee status: Ready (3.0.1). X inactive. Discrete video card is on.
root@xps:# tee /proc/acpi/bbswitch <<<OFF
What is your experience?
