Hi,
I'm running VirtualBox 5.2.8 r120774 on arch (Linux 4.15.6-1-ARCH #1 SMP PREEMPT) and am struggling with crappy guest resolution since the update to version 5.2.6 came out.
In all of my guests I can't get beyond 1280x720 resolution, although my host resolution is 2560x1440.
Before version 5.2.6 my guests automatically resized to the maximum resolution available, so way beyond 1280x720.
I tried almost everything
- completely removed virtualbox,
- reinstalled with current guest addition iso
- uninstalled old guest additions in win7 guest and reinstalled the current version (5.2.8)
nothing helped.
Before the updates to the current version I could also resize the screen resolution of my ubuntu live-cd system to the max available.
Now it is also stuck with 1280x720.
Maybe there's something broken with the QT packages (according to the wiki, VirtualBox has a QT GUI), I don't know.
When I try the Windows-Version of VirtualBox (also 5.2.8), everything is fine, the guest resolution resizing is OK.
Can anyone help me out please ?

I investigated a little bit more...the setting of the virtual monitor always dictates the guest resolution. My monitor count in every VM is one, I don't use a second virtual screen,
but the virtual screen is ALWAYS active and even if I set the resolution of the virtual screen to 1920x1080, I just get big scrollbars at the side of the VM, but the resolution inside the VM doesn't change, even if I manually set it to 1920x1080, the icons stay huge, fonts too, only thing that changes is that the desktop itself becomes huge (at a low resolution).
This reminds me of old xconfig days, where exactly the same happened if you chose a higher resolution of the virtual monitor than the physical one.
It seems that something's really messed up in the current linux version (my best guess is current guest additions) of virtualbox.
I hope this gets fixed with the next release, it's really annoying having to work with a low resolution (2002 is long gone! :-P).

I checked virtualbox at my other arch linux system on my surface, running plasma5 -> same problem.
UPDATE 12-MAY-2018:
Today the update to version 5.2.12 r122571 was released. Updating and installing the new guest additions (5.2.12.0) in my Windows-VMs didn't change the problem.
I'm still stuck with 1280x615 resolution in my guests.
Even with this version these bugs didn't get fixed!
