Hi folks! I've installed Xubuntu 13.10 64-bit in a new VirtualBox guest, and even after installing dkms, linux-kernel-headers and VBoxGuestAdditions the max resolution available still 800x600.
The host PC is a Windows 8 Home Edition 64-bit running VirtualBox 4.2.18.
No errors were reported during VboxGuestAdditions install.
It's a notebook from my company, I can't remove Windows by now... is there any fix to this problem?
