Can´t login with cosmic-greeter and also not with gdm

Hello in the community!

I´m also testing this new desktop environment on a PopOS! But since the last updates I can´t login anymore, not with cosmic-greeter and also not with gdm. I know that this DE is in alpha or before alpha but I would very happy if it´d work :) I´m running PopOS in a virtual machine on my promxox host. (Maybe an important information?)

I´ve this failure messages in system log:

What GPU are you running this on? We are currently having limited support for virtual machines, if you are not passing through a GPU, please make sure your hypervisor as HW acceleration enabled.

Hello,

Thx for your answer.

Ok, when you have limited support for virtual machines that will be the problem I think. And no, I don´t passing through a GPU but what are you mean with HW acceleration?

[Drakulix]

Most VM-tools (VirtualBox, VirtualMachineManager, Gnome Boxes, etc) have an option to enable "Hardware Acceleration" for the graphics card they are emulating.

Ok, I´m using proxmox. There I mean it is only available when a GPU is installed, what isn´t in my host. But I look again
