  • I got black screen and CPU IERR event when I boot from Ubuntu Install Disk (14.x and 15.x), so I tried to add "nomodeset" parameter during install. it will install normal and boot normal. after that I tried to install Intel graphic driver(v1.1.0) . but the issue still occued when boot up without "nomodeset" parameter. Does someone can help me about this? Thanks!!!

    configuration:
    cpu:e3-1285v4
    platform: denlow platform with PCH C226.
    Main OS: Ubuntu 14.10 server x64

  • Hi Tom - I've relayed your question to the devs, I'll see what they say.

  •  Hi Tom,

    My first question is what GPU you have on your machine?

    Please reply here with the output of:

    lspci -nn | grep VGA

    Also, have you tried to remove the nomodeset before install installer? I'd like to know if you also got blank screen on this case.

    But besides anything it is important to report your issue on the right place.  Could you please go ahead and report the blank screen at bugs.freedesktop.org following this instructions: https://01.org/linuxgraphics/documentation/how-report-bugs

    Thanks,

    Rodrigo.
