A few minutes ago 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 the latest kernel.
Confirmed. Weird that the internets doesn't have any other reports of the same. (Except if it actually is the same as https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e85843bec6c2ea7c10ec61238396891cc2b753a9 ) Could it be caused by one of the patches carried by Fedora? What info could help debugging this issue?
https://bbs.archlinux.org/viewtopic.php?id=168767 sounds like same issue ... but no solution.
I just updated to kernel 3.10.9-200 and the issue is still present.
An additional bit of information: When started with the "nomodeset" kernel option the display is no longer distorted but X doesn't start anymore so it seems this is really a intel KMS driver issue.
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 19 kernel bugs. Fedora 19 has now been rebased to 3.11.1-200.fc19. Please test this kernel update and let us know if you issue has been resolved or if it is still present with the newer kernel. If you experience different issues, please open a new bug report for those.
I see exactly the same problem with kernel-3.11.1-200.fc19.x86_64. The Arch link and Dennis' report now both point at https://bugzilla.kernel.org/show_bug.cgi?id=59841 where some progress is being made.
Exactly the same problem, Dell xps 13 FHD. I tested fedora 19 and 20. It works perfectly with kernel 3.9.5-301.fc19 but fails with 3.11.6-200.fc19 and 3.11.6-300.fc20 This affects Fedora 20 too, so maybe the bug must be moved to that category. The problems seems related to UEFI boot, Using legacy boot mode it works.
Here is what the upstream bug says about the pending patch: "Linus just pulled them into his git tree and they'll be in 3.12 (with cc: stable for backporting)." I'm not sure what this means with regards to the kernels present in the current Fedora releases. Does this automatically get picked up? If not it would be a godd idea to include it in the Fedora kernel anyway which should be less contentious now that this fix has been accepted upstream.
Seems this is: commit c6cd2ee2d59111a07cd9199564c9bdcb2d11e5cf Author: Jani Nikula <jani.nikula> Date: Mon Oct 21 10:52:07 2013 +0300 drm/i915/dp: workaround BIOS eDP bpp clamping issue which is indeed CC'd to stable. It isn't queued there yet, but we'll pick it up automatically when it does. I'll work on getting it included into Fedora before then, since the upstream stable maintainer is traveling at the moment.
Please test this build when it completes. It has the patch referenced above, along with the other i915 fixes queued for stable. http://koji.fedoraproject.org/koji/taskinfo?taskID=6120540
I got an 'invalid signature' error trying to boot that kernel. Do I need some additional step?
Are you using a secure boot enabled machine? If so, the scratch build won't work.
It boots now. Now the display is not garbled (Yeah!) but is very dark, mostly unusable. The brightness controls doesn't works, neither manually echoing in /sys/class/backlight/intel_backlight/brightness or /sys/class/backlight/acpi_video0/brightness

We're tracking that issue in bug 903136 (i think).
I can also confirm that with this kernel the display is no longer distorted just extremely dark.
Great. Thank you for testing. We'll get the patch added to the next official build. We'll track the backlight issue in the other bug.
Thanks for your time. If it helps, the sabayon kernel (3.11) works perfectly in this laptop, even the backlight. Maybe worth to look what patchs they apply.

What are the plans for dealing with the brigthness issue with regards to F19? While this specific bug has been fixed the kernel still does not work for these Systems.
Being tracked in the bug mentioned in comment #14.

I installed Fedora 20 Alpha with updates til 2013-11-08 with the new kernel kernel-3.11.7-300.fc20. It worked for me. The notebook is the Dell XPS 13 L322X (Sputnik, FullHD). But now the backlight is off and not changeable. The applet is shown to change the level of brightness, but the backlight remains dark. See Bug Report 1028383, 845077
