Whether starting zcashd during a text-mode only session or gui desktop session, it's producing output that I've saved here:
Of more concern though, during text-mode sessions, these errors are being produced when I run the solveequihash benchmark:
[ 1322.302734] [drm:intel_dp_link_training_clock_recovery [i915_bpo]] ERROR failed to enable link training
[ 1322.311321] [drm:intel_dp_start_link_train [i915_bpo]] ERROR failed to start channel equalization
[ 1322.469883] [drm:intel_cpu_fifo_underrun_irq_handler [i915_bpo]] ERROR CPU pipe A FIFO underrun
Is that output produced by zcashd?
