Would it be possible for you to do a kernel bisection? First, find the last good -rc kernel and the first bad -rc kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/
Then, $ sudo apt build-dep linux $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git $ cd linux $ git bisect start $ git bisect good $(the good version you found) $ git bisect bad $(the bad version found) $ make localmodconfig $ make -j`nproc` deb-pkg Install the newly built kernel, then reboot with it. If the issue still happens, $ git bisect bad Otherwise, $ git bisect good Repeat to "make -j`nproc` deb-pkg" until you find the commit that causes the regression. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1847980 Title: Lightdm is just a black screen when booting kernel 5.3 on an i5-6500, but kernels 5.0/5.2 work Status in lightdm package in Ubuntu: New Status in linux package in Ubuntu: Confirmed Status in xorg-server package in Ubuntu: New Bug description: Xorg freeze at boot on Intel Corporation HD Graphics 530 with linux-image-5.3.0-17 after upgraded to the development release Ubuntu Eoan Ermine (development branch).
