So the 5.15.0-126 is mainline 5.15.167 and 5.15.0-84 is mainline 5.15.116. There are a lot of commits to amdgpu backported in these, so I think we need to narrow down further. ❯ git log --oneline v5.15.116..v5.15.167 drivers/gpu/drm/amd | wc -l 190 I have two asks that can help here. 1) Can you try a newer mainline kernel? 6.11.y or 6.12-rc7? Do these also fail? 2) Could you bisect which commit causes the issue in 5.15.y? If not a proper bisect, there are a lot of mainline 5.15.y builds on this repo: https://kernel.ubuntu.com/mainline/ You can do a "poor man's bisect" if you can narrow down to two closer tags by just taking binary builds and booting them. ** Changed in: linux (Ubuntu) Status: Expired => Incomplete -- 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/2042713 Title: Pale Green blank screen after login Status in linux package in Ubuntu: Incomplete Bug description: Since linux Kernel 5.15.0-86, when I only get a pale green blank screen after login Linux Mint 21.2 Victoria / Cinnamon so I got to use 5.15.0-84.
