OK, found it. I tested drm-tip from http://kernel.ubuntu.com/~kernel- ppa/mainline/drm-tip/current:
Linux winki 4.17.0-994-generic #201806152200 SMP Sat Jun 16 02:03:28 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux and the problem is fixed in that kernel. And looking at the log https://git.launchpad.net/~ubuntu-kernel-test/ubuntu/+source/linux/+git /mainline-crack/log/drivers/gpu/drm/i915 the problematic commit "9081fd9 drm/i915/edp: Allow alternate fixed mode for eDP if available." was reverted there on 2018-05-31. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773581 Title: [Samsung NP900X3G-S01US] Horizontal lines after update to 4.13.0-43 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1773581/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
