Hey @jeff.ohrstrom,

I see that there are settings for resolutions with VNC, that we would normally use on a command line, for OnDemand’s desktop app through turboVNC. However, it doesn’t seem to actually appear (see below unanswered topic):

Hi, sorry for the troubles. I don’t think the link you provided is going to be much help as that was for a separate app a user was trying to get this functionality with.

Here, you’re just trying to run XFCE desktop and change the resolution, which is more straightforward.

Looking at the posted `yaml` though, it doesn’t look like things are formatted correctly from what I see. But, it’s also not raw so I’m unsure.

But, i see you have `bc_vnc_resolution` twice, and it doesn’t look like some of these lines are at the right scope, such as some entries under `attributes`.

Could you possibly post the raw `yml` in so we can ensure the formatting is correct to begin? You can use backticks to do this.

No worries, here is what the yaml looks like @travert .

```auto
title: "Korok Desktop"
description: "This launches a XFCE desktop on the Korok compute nodes."
cluster: "link"
attributes:
  desktop: "xfce"
  bc_vnc_resolution:
    required: true
  bc_num_slots: 1
  bc_vnc_idle: 0
form:
  - bc_num_hours
  - desktop
  - bc_num_slots
  - bc_vnc_idle
  - bc_account
  - bc_queue
  - bc_vnc_resolution

```

What does it render when you do this:

```auto
title: "Korok Desktop"
description: "This launches a XFCE desktop on the Korok compute nodes."
cluster: "link"
attributes:
  desktop: "xfce"
  bc_num_slots: 1
  bc_vnc_idle: 0
form:
  - bc_num_hours
  - desktop
  - bc_num_slots
  - bc_vnc_idle
  - bc_account
  - bc_queue
  - bc_vnc_resolution

```
