[Kernel-packages] [Bug 1785481] Re: amdgpu WQHD resolution(2560 × 1440) not available
Donk, the next step is to fully reverse commit bisect from kernel 4.15 to 4.16.18, in order to identify the latest kernel commit that did not work followed immediately by the next kernel commit that did work. This will allow a consideration of the fix commit for backporting. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ? This article was written for folks who don't know anything about linux, so it's easy to follow. Please note, finding adjacent kernel versions, or providing a commit without testing it and reverting it is not fully reverse 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 confirmed via testing, you then mark this report Status Confirmed.

[Kernel-packages] [Bug 1785481] Re: amdgpu WQHD resolution(2560 × 1440) not available
Donk, in order to allow additional upstream mainline kernel developers to examine the issue, at your earliest convenience, could you please test the latest mainline kernel? Please keep in mind the following: 1) The one to test is in a folder at the very top of the page (not the daily folder). 2) The release names are irrelevant. 3) The folder time stamps aren't indicative of when the kernel actually was released upstream. 4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . If testing on your main install would be inconvenient, one may: 1) Install Ubuntu to a different partition and then test this there. 2) Backup, or clone the primary install. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the mainline kernel, please comment on which kernel version specifically you tested. If this issue is not reproducible in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the Bug Description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists. If the issue is reproducible with the mainline kernel, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Also, you don't need to apport-collect further unless specifically requested to do so. It is most helpful that after testing of the latest mainline kernel is complete, you mark this report Status Confirmed. Lastly, to keep this issue relevant to upstream, please continue to test the latest mainline kernel as it becomes available. Thank you for your help. ** Tags added: latest-bios-3003 -- 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/1785481 Title: amdgpu WQHD resolution(2560 × 1440) not available Status in linux package in Ubuntu: Incomplete Bug description: Hello, I use ubuntu 16.04 with hwe stack and an Radeon R9 285.
