Linux Mint 19 800x600 Resolution Help

[Chris Taylor]

Hi, I've installed Proxmox 5.3-8 on my Dell r410 server and installed Linux Mint 19.

The installation went fine and all works however the last issue I'm having is getting the screen resolution to change to something more usable than 800x600.

I run the VM over VNC. I've tried several solutions via Google searches.I've changed the display hardware options to VMware compatible. Enabled QEMU agent under the options. Installed the qemu agent on the Linux VM and I'm still not able to change the screen resolution.

At this stage I'm out of ideas myself. Is there anything I'm missing?

Please post your VM config

> qm config ID

how do I actually do that?

how do I actually do that?

just open a console to your host or connect via your favorite SSH client.

as soon as you have a command line as root, just type:

> qm config 100

(100 is the ID of your virtual machine, just replace this with yours)

sometimes the guest does not correctly list all available options for the resolution and they must be set in the xorg.conf for example

see one guide here for example: https://forums.gentoo.org/viewtopic-t-979150-start-0.html
