I have an HP Pavilion G4 AMD A10-4600M APU with Radeon(tm) HD Graphics × 4 14.04 Trusty
For some time now, whenever I suspend notebook either by shutting lid or manual suspension screen is off. Recently by chance I have tried to resume whyle hooked to external HDMI TV and realised that HDMI is set to default output on suspension. both video and audio output go to HDMI as usual. But trying to get back to notebook screen gets me nowhere, it remains turned off untill rebooted.
I have also noticed that despite having HDMI unhooked, HDMI audio output device is still detected.
Can anyone shed some light to this issue?
