Problem:<\/font><\/strong> <\/p>\r\n

Booting Image for Linux (either the CUI or GUI version) results in a black screen instead of the IFL menu or desktop. This issue affects some newer laptops (e.g. Dell Latitude 5289, Lenovo e-560), but may also affect other systems.<\/p>\r\n

Solution:<\/font><\/strong><\/p>\r\n

To avoid this issue you will need to add the acpi=off<\/strong> Linux kernel boot parameter before booting. The method for doing this depends on whether you're booting the IFL media in Legacy or UEFI mode.<\/p>\r\n

Booting Legacy Mode IFL Boot Media<\/strong><\/font><\/p>\r\n

When booting to IFL the initial screen operates with a five second timeout and has selections for various graphics options. A "boot:" prompt is displayed where you can enter your selection.<\/p>\r\n

Instructions:<\/strong><\/p>\r\n

    \r\n
  1. Once at the "boot:" prompt, within five seconds, enter the number of the graphics selection of your choice. This will abort the countdown and allow you to enter the kernel boot parameter.

    <\/li>\r\n
  2. Type a space.
    \r\n
    \r\n <\/li>\r\n
  3. Type the kernel boot parameter: acpi=off<\/strong>
    \r\n
    \r\n <\/li>\r\n
  4. Press ENTER to boot IFL.<\/li>\r\n <\/ol>\r\n

    For example, to boot the default graphics option, you would type: 1 acpi=off<\/strong><\/p>\r\n

    Booting UEFI Mode IFL Boot Media<\/strong><\/font><\/p>\r\n

    <\/strong>When booting to IFL the GRUB menu is displayed. The initial screen operates with a five second timeout and has selections for various graphics options.<\/p>\r\n

    Instructions:<\/strong><\/p>\r\n

      \r\n
    1. Once the GRUB menu is displayed, within five seconds, select (highlight) the graphics option of your choice and press e<\/strong> to edit the menu item.
      \r\n
      \r\n <\/li>\r\n
    2. The GRUB commands for the menu item will be displayed in a simple editor. An example entry is shown below (spacing will likely be different):
      \r\n
      \r\n setparams 'IFL (GUI) Network Boot Disk - best available graphics mode'
      \r\n
      \r\n     set background_color=black
      \r\n     gfxpayload='1024x768,800x600,640x480'
      \r\n     echo     'Loading vmlinuz...'
      \r\n     linux   \/vmlinuz uefimode=yes iflkmap=us ktl=qwerty iflbflag=2
      \r\n     echo     'Loading initrmfs.gz...'
      \r\n     initrd  \/initrmfs.gz<\/font>
      \r\n
      \r\n <\/li>\r\n
    3. Use the arrow keys, END key, etc. to move to the end of the linux<\/strong> line of text.
      \r\n
      \r\n <\/li>\r\n
    4. At the end of the line, make sure there is a space and then type: acpi=off<\/strong>
      \r\n For example:
      \r\n linux   \/vmlinuz uefimode=yes iflkmap=us ktl=qwerty iflbflag=2 acpi=off<\/strong><\/font>
      \r\n
      \r\n <\/li>\r\n
    5. Press F10 (or Ctrl-x) to boot the modified menu item.\r\n\r\n <\/li>\r\n <\/ol>","protected":false},"excerpt":{"rendered":"
