Can you further narrow down which kernel version between 3.16 and 4.1 introduced the problem? |
With newer kernels, display resolutions under 60Hz the attached monitors (tried multiple with multiple modes on DVI and display port) fail to sync. Working kernel: 3.16.0-4-amd64 (Debian) Non working: 4.1.0 (Debian), and 4.3.0-rc6 (mainline). My main monitor is a 4k resolution monitor which will only supports 30Hz at the default full native resolution. [ 14.102283] [drm] radeon kernel modesetting enabled.
