Hi, I'm investigating an issue with KMS on my graphics card. I'm hoping this list might give me some direction/guidance where to look. Sometime in between kernels 4.9 and 4.14, the KMS on my card stopped getting set to 2560x1440 and only sets 1920x1080. Passing video= as a kernel parameter just leads to a black screen. I've tried stock kernels on alpine and arch, and also compiled a few as well; I can't see any obvious differences in the compile options that might lead to the difference. My next line of enquiry is to see if there's a change in amdgpu that might be the cause. Given the size of the codebase and the number of changes, I was hoping someone might be able to help me narrow the possible search. Would you be able to suggest somewhere to begin ? The card is a Sapphire R9 380X NITRO 4GB - it identifies as a TONGA. During the boot, I get this message about the mode setting [drm] initializing kernel modesetting (TONGA 0x1002:0x6938 0x174B:0xE308 0xF1) thanks Ian -------------- next part -------------- An HTML attachment was scrubbed...
