Londé Ngosso, to advise, you don't need to keep re-posting the same system information, log attachments, error messages, etc. unless specifically requested to do so.
Despite this, to clarify, the scope of this report is only if the functionality of hdmi is working (not innocuous error messages in logs). Hence, to see if the hdmi issue is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results? ** Summary changed: - [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun + hdmi not working ** Description changed: - Hello, - - I get an error on my laptop with ubuntu 14.04 and kernel 4.5 RC2.
