[SOLVED] linux Mint (Ubuntu, Debian) SPICE display resolution

[EllyMae]

I'm running Linux Mint in a guest VM. Having trouble changing the SPICE display resolution. I've tried everything that I could think of, after much reading on the topic.

I have the VM hardware option set to SPICE with 64MB of storage:

I have the vdagent task running in the guest:

I have restarted the guest many times.
After restarting the guest VM, selecting the SPICE console and logging in to the guest, I get this notification:

I launch the driver manager, but it doesn't find anything that needs to be installed.
I then go to the display hardware settings:

If I try to make any changes and click on Apply, this is what I get:

Then, my host screen usually gets messed up, and I have to reboot the guest and try again.
Does anybody know what's going on here?
Thanks a million.

i don't know about mint, but on debian at least there is the 'xserver-xorg-video-qxl' package that could help
alternatively you could try to use the virtio gpu instead (should also enable spice for recent pve installations)
what kernel does the guest use? also can you post the complete vm config? (qm config ID)

I changed it to Virtio-GPU, and it's working great! And, yes, it did enable SPICE.

Kernel: 5.15.0-41-generic x86_64

The VM config is below.

Thank you so much for your help.
