Anybody else noticed that bumblebee and bbswitch stopped working after the latest update to Fed18 (kernel-3.7.4-204.fc18.x86_64, xorg-x11-drv-nouveau-1.0.6-1.fc18.x86_64, etc.)
This on a laptop with optimus (intel/nvidia).
Could the fact that "/sys/kernel/debug/vgaswitcheroo/switch" is now a default entry and that "vga_switcheroo" is enabled have anything to do with it.
dmesg |grep switcheroo [ 13.840837] VGA switcheroo: detected Optimus DSM method _SB_.PCI0.PEG0.PEGP handle [ 16.711017] vga_switcheroo: enabled
cat /sys/kernel/debug/vgaswitcheroo/switch 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :Pwr:0000:01:00.0
