Have you guys tried uninstalling the Intel Xorg driver so you default to kernel mode settings.

I'm having this same issue on a Dell 7537 running Ubuntu 16.10 (kernel 4.8). The flickering that occurs is a rapid change in the brightness of the screen, in a random, persistently manner (it never stops). Not so often the screen goes all white and quickly returns to normal. It's interesting to mention that on Ubuntu 16.04 (kernel 4.4) the bug appears to be fixed, as the flickering does not occur. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1554613 Title: Screen flickers on XPS 13 9350/9550 (Intel Skylake/Broadwell GPU) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1554613/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Can anyone please post the instruction to revert this and go back to normal Xenial kernel release when the bug is fixed there?

Amazingly, Bluetooth ON/OFF seems to have an effect on this bug. I have been running with Bluetooth constantly ON for the past couple of days and have seen no flicker at all. As soon as I turn off Bluetooth a flicker occurs after a couple of minutes. I also copied the firmware file from the Windows drivers for the Dell Wireless 1830 card as Bluetooth wasn't finding any devices without it. I am not 100% sure, but I think before adding the bluetooth firmware I got flicker with Bluetooth ON as well. You can get the firmware file from this thread - https://bbs.archlinux.org/viewtopic.php?id=204739 I am running an XPS 9550 with an i7-6700HQ. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1554613 Title: Screen flickers on XPS 13 9350/9550 (Intel Skylake/Broadwell GPU) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1554613/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@eugenesan but the workaround you posted in the summary lists mainline kernels. These kernels still have the problem so they are not work arounds.

@pranith On my system, 4.6.0rc3+intel-drm-next solved the issue. Other people report solution only with more recent version, 4.6.0rc5+intel-drm-next. The difference in reports might be related to installed BIOS version or/and power management behavior in different conditions.

Skylake has been out for 7 months and we still have problems Ok, I looked into that bug and it seems its not the same. It specifically mentions external monitors and also not black screen flickering, but more a graphical flickering, without the completely black frames in between. Nevertheless, I tried the proposes patches from https://bugs.freedesktop.org/show_bug.cgi?id=91393#c102 on intel-drm- nightly and I still got the FIFO underrun ERROR and also the black screen flickering. So thats not a solution. Also, it seems that the FIFO error does appear for the first flicker, but not for any ones after the first, so in my opinion, it can be used as an error criteria. I could bisect the kernel further, but as seen in https://bugs.freedesktop.org/attachment.cgi?id=123104 there are so many commits, which I cannot build. Maybe someone can help me to compile one of these? I can then do the remaining (since they are all in order, it seems like the reason they dont compile might be the same). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1554613 Title: screen flickering on XPS13 9350 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1554613/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Skylake has been out for 7 months and we still have problems I am starting to believe that the common error [drm:intel_cpu_fifo_underrun_irq_handler [i915_bpo]] *ERROR* CPU pipe A FIFO underrun is not actually responsible for the flicker. To be more precise, the FIFO underrun may result in conjunction with a flicker, but is not a unique indication. I am currently bisecting the kernel and right now I am on commit 5ffd4da+. This commit does show the FIFO underun but not at the same time the screen turns completely black for a split second. I assume the flicker (screen completely black for a split second) is not directly mapped by the FIFO underrun. Reading https://bugs.freedesktop.org/show_bug.cgi?id=91393, I think our bug is at least related, if not identical. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1554613 Title: screen flickering on XPS13 9350 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1554613/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I am currently bisecting the kernel again and one thing I realize is that I can detect an error through dmesg and then set the commit to bad, but after reviewing some kernels which I have marked as good, it turns out these were bad too. This messed up my bisect and I have to start over again. Does anyone know how to specifically excite the error? So far I mostly open chrome and open netflix and youtube, since browsing through the galleries sometimes helps to see the bug, but unfortunately not always. Any method is welcomed and could speed up my bisect a lot :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1554613 Title: screen flickering on XPS13 9350 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1554613/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Flickers seem to happen essentially when the > machine is more or less idling. I believe I am having the same problem. I am on XPS 13 9350 too, and now on 4.6-rc3 kernel. And yes the flickers do tend to occur when the machine is kind of idling. My suspicion is that it has something to do with RC6. When I change the i915.enable_rc6 parameter from 7 to 0, the flickering seems to go away. The problem is, of course, disabling RC6 will drain battery a lot faster. PS. I notice that even with i915.enable_rc6=7, the GPU never goes to RC6p and RC6pp. Is that not supported on Skylake yet? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1554613 Title: screen flickering on XPS13 9350 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1554613/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
