I've installed KALI 2017.3 in a virtual box VM.
I also installed the guest additions and upgraded all the graphics drivers available.
The auto-adjust feature is greyed out. As well as choosing resolution for the display (in the bottom right of the VM window, on the display icon)
The maximum resolution I can choose inside KALI, in the system configuration, is 1024x768.
What am I missing? What else can I try to get auto-adjust resolution feature working?
edit about the suggestion to mark as duplicate of Why is Kali Linux so hard to set up? Why won't people help me?
It turned out eventually, that this was because of a missing feature in the kernel version supplied with the current KALI iso image, which was not trivial from the issue and error messages. So, this question and answer could be helpful even to experts in KALI.
As a personal side-note, I disagree with notion that a question should not be asked if the subject is "expert level". Even experts could find themselves tackling an unusual issue that may appear to be basic. In fact, it's probably mostly experts.
