Display scaling not working in Manjaro guest running kernel 5.2 in VirtualBox

I upgraded the kernel to 5.4. The problem that autoscaling doesn't work persists.
$ sudo dmesg does not give me any errors.

$ sudo /usr/lib/systemd//systemd-modules-load gives me no erors either. I have no dkms installed.

What might be wrong here?

What DE, my experience is it works only on KDE, GNOME, XFCE4.

I use xfce in the guest and kde in the host.

In the guest can we see:

pacman -Qs virtual
systemctl status vboxservice.service
uname -sr

What graphics controller do you use, and is your host linux as well?

Can you check that the vboxvideo module is loaded in the guest (e.g. lsmod | grep vbox)? If not, load it with modprobe vboxvideo.

Those are good pointers.

I got the service to run with $ systemctl start vboxservice

I also enabled it now:

$ systemctl enable vboxservice.service
Created symlink /etc/systemd/system/multi-user.target.wants/vboxservice.service → /usr/lib/systemd/system/vboxservice.service.

Will reboot to see if that works [edit: nope]

If the vboxservice wasn't running, that means the guest utils weren't running.

Its all quite strange. I set the graphics adapter too the most dumb one (vboxvga).


$ mhwd -li
Installed PCI configs:

              NAME               VERSION          FREEDRIVER           TYPE

  video-virtualbox            2018.11.25                true            PCI

Fixing/Improving Virtual Machine support (use vboxsvga) seems to contradict Can't auto-resize guest display in VirtualBox (use VBoxVGA).
Not sure about the recommended graphics adapter now..


$ sudo mhwd -r pci video-vmware
Error: config 'video-vmware' is not installed!

$ sudo mhwd -i pci video-virtualbox
Error: config 'video-virtualbox' does not exist!

Remvoed video-virtualbox in the hope to install it later, but now i have video-virtualmachine installed and I cannot install video-virtualbox anymore..

Video-virtualmachine replaces video-virtualbox.

Ah thx, it doesn't take away the issue nonetheless.

Does anybody know the as per Manjaro recommended settings? No combination acutally makes auto-resizing works. Some combination gray out that item alltogether in the menu.

Manjaro and VirtualBox have different ideas about the recommend graphical adapter. None works.
