            Bug ID: 60881
           Summary: Dell XPS 13 (L322X) display does not work anymore with
                    kernel 3.10
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.10
          Hardware: All
                OS: Linux
              Tree: Fedora
            Status: NEW
          Severity: high
          Priority: P1
         Component: Video(DRI - Intel)
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: dennisml at conversis.de
                CC: intel-gfx-bugs at lists.freedesktop.org
        Regression: No

I updated my Dell XPS 13 (aka "Sputnik") and after the reboot I only got a
completely garbled display as if the display frequency isn't right for the
monitor.
Once I boot into the previous 3.9 kernel things start working again as
expected. It seems the driver got broken in kernel 3.10.

When started with the "nomodeset" kernel option the display is no longer
distorted but X doesn't start anymore but that might be related to Fedora 19
not handling the non-KMS fallback case well (Xorg aborts with no usable screen
configuration).
