[Kernel-packages] [Bug 1824216] Re: Linux 5.0 black screen on boot, display flickers (i915 regression with certain laptop panels)
Kernel 5.0.0-13 currently in proposed fixes this issue on my XPS 15 2-in-1 (9575) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1824216 Title: Linux 5.0 black screen on boot, display flickers (i915 regression with certain laptop panels) Status in linux package in Ubuntu: Fix Committed Status in linux source package in Disco: Fix Committed Bug description: [Impact] On my Dell XPS 9575, I get a black screen on boot when running the 19.04 live image, OR after updating from 18.10 to 19.04. It appears to be a kernel related bug that was introduced in 5.0 that is affected by certain laptop panels not conforming to their stated specifications. Several other Dell systems exhibit the same issue, and it's very possible that there are other panels used on other systems that will also have the same issues. Intel is aware of this issue and has already created a patch. You can see the relevant threads here: https://bugs.freedesktop.org/show_bug.cgi?id=109959 And the patch here: https://patchwork.freedesktop.org/patch/296411/ It would be fantastic to get this patch applied before release, as it would be very difficult install 19.04 on the affected systems otherwise. I was able to get the live image booted by adding the nomodeset kernel parameter to grub, so as a work around you can use this approach to install.
