Here is the error spam I get: Failed to start VirtualBox Guest VMSVGA resize client. See ‘systemctl status vboxdrmclient.service’ for details.
This goes on and on for around 30s and all I get is a black screen after that.
I’ve tried rebooting the system, reinstalling and reloading virtualbox but I get the same error.
virtualbox virtualbox-host-modules virtualbox-guest-iso are for your HOST system, if your system is Manjaro or Arch based system, in principle the host-modules for your running kernel; example:
if your host run Manjaro with the 5.8 kernel then linux58-virtualbox-host-modules will be installed.
virtualbox-guest-utils will install automatically in the GUEST if you run Manjaro on a VBox install.
The DKMS are usualy good if there are no precompiled host modules for your running kernel. Manjaro provides them.
