I'm having an issue with my Ubuntu Server 16.04 installation. I have it running on a Zotac Z-Box CI23 Nano. It installed fine, but on its first boot all I had was a blank screen. I edited /etc/default/grub and changed GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"

This let me see the startup, but the text is all garbled white blocks:


I first thought it might be a bad cable, so I switched cables with no change. I changed monitors with no effect. I switched to a TV using HDMI with no effect.

Any ideas would appreciated.


I finally got this figured out. At first I thought it was bad hardware so I RMA'd the machine. The same exact thing was happening on the replacement. So I spent a few hours fiddling with grub settings. This is what ended up working for this machine:

in /etc/default/grub:

Comment out GRUB_CMDLINE_LINUX_DEFAULT="splash quiet" entirely. Uncomment GRUB_TERMINAL=console

Uncomment GRUB_GFXMODE=640x480 I set it to GRUB_GFXMODE=1280x800 because that's the monitor I'm using's default.

Save it then sudo update-grub and reboot and it is showing as expected. Only the combination of those three changes seem to make it work for me, but YMMV.

  • Are you saying the problem is solved? If so can the bounty be removed? – WinEunuuchs2Unix Aug 26 '16 at 2:30
  • Yes it can, I couldn't figure out how to remove it. – ColLeslieHapHapablap Aug 26 '16 at 7:58
  • @boredemt It can't be removed. You can't award it to yourself AFAIK. But, after the bounty period ends, you might get half of it back, if your answer is the most-upvoted one (sorry, don't have much info on that). – EKons Aug 27 '16 at 12:35
