Thomas Diesenreiter, the next step is to fully commit bisect from 4.13.4 to 4.15.17, in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions, or providing a commit without testing it and reverting it is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. It is most helpful that after the bad commit (not kernel version) has been confirmed via testing, you then mark this report Status Confirmed. Thank you for your help. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1771204 Title: Horizontal lines on Samsung Laptop np900x3f after Update to 18.04 Status in xorg package in Ubuntu: Incomplete Bug description: My laptop was running fine for years, but after the latest update to 18.04 and the reboot there were horizontal lines everywhere.
