apport information ** Package changed: xorg (Ubuntu) => bbswitch (Ubuntu)
** Summary changed: - Suspend does not work + bbswitch prevents suspend and taints kernel ** Tags added: apport-collected ** Description changed: When initiating suspend (to RAM), the kernel gets tainted. This is a regression that appeared after upgrading from Kubuntu 13.10 to 14.04. My computer has a discrete nVidia card (hybrid SLI system, on ASUS UL80VT).
