I am running openhabian on Ubuntu Server 18.04, hosted on VMware ESXi 6.5. Open-VM-tools is installed and updated to its current version.

When I first run openhabian I am greeted with a warning, which suggests a column increase, ergo my dilemma. I surmise that a resolution increase would help, but I seem to be stuck at 800x600 (measured against a desktop 17.04 instance). Working on a change of $COLUMNS (also failing gain persistence) didn't work either.

There are a lot of older posts on resolution changing, none of which have worked for me. I have modified /etc/default/grub in a variety of ways to no avail, nothing has worked, no matter my combination of changes to:


Upon any change, I always to a sudo update-grub and reboot to test. I have also tried modifying /etc/grub.d/00_header which didn't help.

On top of this, I tried a solution for changing the columns variable here with no luck. Although a temp change didn't seem to make the warning go away either, so I am still leaning to this being a resolution issue.

For the life of me, I can't get any of this to change, but I'm happy to try any suggestions. Thanks!

Also, I'm fairly new to Linux, so my apologies if I have completely missed the obvious here.


I have mostly resolved the resolution issue here... I am going to remove some of the random things I've added below to see what exactly is necessary and then retry by rolling back to a previous snap shot. As anticipated, the resolution is proportional to $COLUMNS, with 1024x768 allowing 128.

FWIW, here is the current changes that I have in place:

  1. Removed svga.guestBackedPrimaryAware = "TRUE" from .vmx file
  2. Increased video ram from 4MB to 16MB per: https://kb.vmware.com/s/article/2152053
  3. Avoided wide-screen resolutions (initial desire was 1280x800, I have it working at 1024x768)
    • GRUB_GFXMODE=1024x768

The more I edit this solution, the more I feel 'special' :)
