+ [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.
+
+ [Test case]
+ boot a kernel with the revert
+
+ [Regression potential]
+ shouldn't be any, since this reverts to what was used on kernels before 5.0
