Correction: I'm still getting a second or two of complete screen freezing every now and then. The kernel says: [69400.016524] [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A (start=19 end=20) time 198 us, min 1073, max 1079, scanline start 1068, end 1082 So something might still be a bit buggy. _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
