Arch Linux

VMSVGA window resizing is not working under wayland (gnome via gdm). I haven't tested X. Tested with a fresh Arch guest running under a VirtualBox 6.1.12 host.

To recreate this you can `pacman -Syu gnome gdm virtualbox-guest-utils` and reboot

I assume the window resizing is broken is because the vboxdrmclient.service fails with exit code 252. I can't seem to get any more ouput on the failure than that.

Could this possibly be related to /usr/bin/VBoxDRMClient missing the setuid bit?

```
$ sudo journalctl -b0 -u vboxdrmclient.service

Jul 16 11:25:20 measurebox systemd[1]: vboxdrmclient.service: Failed with result 'exit-code'.
```

FYI VMSVGA window resizing is working if the guest additions are installed via the official Guest Additions ISO from oracle and their VBoxDRMClient binary has the setuid bit.
