Help!  
I’m working remotely via zboost/rgs, hp z8, centos7.6, flame2022\_2.

This may not be totally relevant, but I was attempting to install Blender using these instructions:

> **[Install blender on CentOS using the Snap Store | Snapcraft](https://snapcraft.io/install/blender/centos)**
>
> Get the latest version of blender for on CentOS - Blender is the free and open source 3D creation suite.

all seemed good, but when I loggged out and back, the resolution is locked at 640x480(!).

Theres no options in the nvidia x server setup utility to amend this. If I run xrandr in a terminal there are no other resolutions available.  
I suspect what may be happening is that the physical gui monitor (in the suite) is off / not responding and so centos is defaulting to a lo-res display setting.  
zboost cannot seem to force a higher resolution either.

I’m waiting on someone to have a look locally, but in the meantime,anyone any ideas how to fix this without physically being in the room to check things?
