then i installed ubuntu-mate-desktop,, it did its thing, and it worked. I messed it up so bad that i actually had to reinstall ubuntu because the apply button was completly off screen, and i could not change resolution back, so i reinstalled ubunto and it worked fine. So, first i stalled ubuntu through virtualbox, and it worked, however whenever i go to set the screen resolution, anything past 1360x768 goes right off the screen making it impossible to use properly. I hope this can help other frustrated folks out there.I have been using linux for a while, so im pretty good with figuring things out, however this one has got me stumped. Burp and ZAP look fine and everything seems to be functioning correctly at this point. I changed it to 200%, started the Kali guest and it works!!! Finally. So I poked around settings for the VM again and noticed a 'Scale Factor' setting under Display. It worked! Sorta.Īpplications launched by Java (i.e., Burp, ZAP, etc.) were not scaling properly and still displayed in tiny windows with tiny font. I think I get it to work by changing guest's resolution to max (3840x2160) and then scaling to 200% in full screen mode. I tried all the suggestions you've seen here and more. But I figured if I installed virtualbox guest additions, the problem would resolve. I noticed the problem right away during installation - a tiny window made that experience a constant eye test. Latest virtualbox (5.2.16 in this case) I ran into the same issue most of you are seeing: It seems as if VirtualBox didn't understand the actual natural resolution of the screen I'm using when running without guest additions and as if the guest additions helped it understand the natural resolution, but failed to handle the screen accordingly. When I boot an iso of an ubuntu as a novel VM it uses the full screen but at a horrific resolution (my display is 4k but I get something like 1900x1080), and again, when I change the resolution in the guest then only a part of the screen is rendered at the previous resolution. I also noticed that trying to install the guest additions causes a lot of messages in the guest additions installation window mentioning a return code 2 (it then asks me to reboot the guest and windows tells me that guest additions are an installed program, so may be that's not really an issue). I noticed that deinstalling the guest additions leads to a situation where the guest's screen does not scale back to the top left corner, but everything remains in low resolution on the full screen.

When I change the resolution in the guest it essentially only changes the size of the guest's screen, keeping the rendering at the old resolution (hence the guest screen then is larger than the host's 'window' and hence parts of the guest's screen are hidden). The host is in full screen with a very low resolution until windows starts, then it scales to the top left corner, while the mouse still takes input from the complete screen (so input and rendering do not correspond anymore). I know I'm late to the party, but was there any followup on this? I am having exactly the same problem, only with the opposite OS situation (host is Ubuntu, guest is a Win 8.1).
