[Kernel-packages] [Bug 1768152] Re: Brightness controll doesn't work - Samsung R560
Thomas, the next step is to fully commit bisect from kernel 4.4 to 4.15 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 from a kernel version bisect is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. It is most helpful that after the fix commit (not kernel version) has been identified, you then mark this report Status Confirmed. Thank you for your help. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Summary changed: - Brightness controll doesn't work - Samsung R560 + [Samsung NP-R560-AS05DE] Brightness control doesn't work ** Tags added: kernel-bug-exists-upstream-4.17-rc3 needs-bisect regression-release -- 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/1768152 Title: [Samsung NP-R560-AS05DE] Brightness control doesn't work Status in linux package in Ubuntu: Incomplete Bug description: Hi, I just migrated from Gentoo Linux to KUbuntu 18.04 LTS.
