研究方向

Start by tracing how VBoxDRMClient and the VBoxClient vmsvga-session process are started for Guest Additions on Arch Linux with XFCE. Compare that setup with the working VBoxClient --vmsvga command in the report, then inspect the uploaded logs for clues. Done means automatic resizing works after resizing the VM window without manually restarting either process.

What happened?

Automatic guest display resizing doesn't work on guest system with Arch Linux x86_64/XFCE and VirtualBox Guest Additions 7.2.22. Resizing the VirtualBox window does not change the guest display resolution.

However, the following workaround fixes the problem immediately:

$ sudo pkill -x VBoxDRMClient
$ pkill -f '^/usr/bin/VBoxClient --vmsvga-session$'
$ VBoxClient --vmsvga -f -v

After running these commands, automatic display resizing works correctly.

How can we reproduce this?

The host system is Arch Linux x86_64 running Oracle VirtualBox 7.2.22 r175245. The guest system is also Arch Linux x86_64, with XFCE running and virtualbox-guest-utils 7.2.22-1 installed. The VM uses the VMSVGA graphics controller, and the vboxservice service is enabled and running.
