Black screen when running on VM

[wiiznokes]

I tried to build this in a VM, using QEMU/KVM with virt-manager. I notice there was 3 libs that was missing from the read-me:

• cargo
• libgbm-dev
• libclang-dev
• libpipewire-0.3-dev

I was using PopOS 22.04. Also, sudo apt install cosmic-* doesn't worked somehow.

So after having successfully build the project, I made

• sudo mkdir -p /var/lib/extensions
• sudo cp -r cosmic-sysext /var/lib/extensions
• sudo systemctl enable --now systemd-sysext
• sudo systemd-sysext refresh

Then after re login or reboot, when I choose Cosmic and enter the password, there is a black screen :(

I can type word like in a shell, but I can't type command. If I make ctrl-c, I go back to login.

VM support isn't great at the moment (e.g. see a similar issue for virtualbox here https://github.com/pop-os/cosmic-comp/issues/38). You need to emulate a gpu with sufficient acceleration capabilities right now.

I managed to make it work with virtualbox :)

Would a pull request with the libraries I listed and the cp command would be useful ?

The cp-command and the rest of the shell commands not so much. I want people to read about systemd-sysext and the caveats instead of blindly following instructions, to understand that this is not meant as a permanent installation and mostly for testing of pre-alpha software.

The missing libraries however I would appreciate very much. Thanks for documenting those.

Done :)
