When I boot up and choose Ubuntu (I use dual boot, also I run dual screen setup), the VGA and HDMI do not configure properly when HDMI is plugged in. If HDMI is not plugged in the VGA works fine. How can I fix this issue?

  • Why do I have to edit my question? It is pretty straight forward. May 9 '19 at 23:21
  • Before attempting to solve your problem, I need to know about HDMI port(s), and other ports such as VGA or DP that your system supports. Are they alive or disconnected? What are the default and recommended screen resolutions? Are drivers up and running? HDMI carries not only video but also audio. So the state of audio daemon should also be known. @Mike Peterson, if it is pretty straight forward then why is the system not behaving as you expected?

  • Does your external monitor have DP (Display port)? If so, please connect your computer with external monitor through DP instead of HDMI and test whether it works. Please report.
