Zamundaaa <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |WAITINGFORINFO Status|REPORTED |NEEDSINFO --- Comment #6 from Zamundaaa <[email protected]> --- Alright, so bandwidth is the problem: [ 129.170690] amdgpu 0000:05:00.0: [drm] Mode Validation Warning: Total vertical active bandwidth failed validation. [ 129.170693] amdgpu 0000:05:00.0: [drm:amdgpu_dm_atomic_check [amdgpu]] DC global validation failure: The operation is not supported. (24) [ 129.170881] [drm:sdma_v4_0_process_trap_irq [amdgpu]] IH: SDMA trap [ 129.170915] amdgpu 0000:05:00.0: [drm:amdgpu_dm_atomic_check [amdgpu]] Atomic check failed with err: -22 Afaik "Total vertical active bandwidth" refers to the GPU side and not the cable/display, so the format+modifier changes should've helped. Does limiting color resolution on either display help? Also, which "color accuracy" setting are you using? About the DisplayPort screen freezing after this happens, from the log it seems like KWin continues to present new frames just fine, so that bit might actually be a driver bug. -- You are receiving this mail because: You are watching all bug changes.
