Public bug reported: This bug was reported after running a system update. It has had no immediately visible effect.
Some hardware specs: Dell XPS 15Z with Nvidia Optimus card. Had quite a struggle installing and getting 14.04 up and running with native resolution. Modifications I have made: GRUB: I have tried some different settings to avoid a black screen after the GRUB boot page. Currently it looks like this: GRUB_CMDLINE_LINUX_DEFAULT="" GRUB_CMDLINE_LINUX="acpi_osi=linux noapic nolapic i915.i915_enable_rc6=1 i915.lvds_downclock=1 i915.i915_enable_fbc=1 pcie_aspm=force" Bumblebee installed and things seem to be running relatively stable (mouse lagging after suspend some times though).
