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
