Virtualbox - Full HD Resolution with Fedora Guest

[Sanctioner]

Hello,

This topic is discussed all over the digital world with videos, how-tos, step-by-step instructions. Most of them are different from all of the others. I have spent the past 6 hours trying them all. I must have found and tried about tens of them. None of them work.

I'm not sure if this is the most appropriate place to ask, or a Fedora forum, but i will ask here first. I am using Fedora 23 - Cinnamon on a Win7 host.

The resolution is stuck at a horrid 1024 x 768. I'm surprised the start menu fits completely inside of it. There is barely any space around it. It is completely unusable at this low res.

Most instructions have a few basic steps. Here I tried it as well as a bunch of other things which was hours ago that I cannot recall.

* install guest additions on host
* closed vbox and everything that it spawns
* ran this in windows: "VBoxManage.exe setextradata "Fedora" CustomVideoMode1 1920x1080x32"
* "VBoxManage.exe getextradata "Fedora" CustomVideoMode1" to verify that it took.
* added VBoxGuestAdditions.iso as a CD-ROM to Fedora in vbox manager
* started Fedora (it started in 1024 x 768)
* once in, clicked Devices, then Insert Guest Additions CD Image
* clicked File, Preferences, then Extensions
* verified extension pack is installed
* shut down. and started it again
* Fedora keeps opening in 1024 x 768. i went to display resolution in Fedora control panel and there is no other resolution available to use. I hit [right-ctrl]+[F] but the screen stays the same resolution while maximized, just a lot of black around it.

My hardware is capable of running 50 of these simultaneously. Windows7 is installed on and utilizing UEFI if that matters.

Can anyone help to find out what I am missing? I would appreciate if we work on the easiest things first, then expand to include outrageous workarounds later if we can find out why the easier solutions aren't working. I believe it is capable right out of the box but I am open-minded and just want it working.

Thanks,
-Sanc

The extension pack is not relevant to graphics, only the Guest Additions involves a new graphics driver.

Nor is it necessary to set a video mode hint. All that does is tell the virtual graphics adapter to offer a video mode - you can't force the guest OS to select it.

Try setting VirtualBox graphics preferences (GUI|File|Preferences|Display) MaxGuestDisplaySize to None, install the GAs and make sure they're running, then tell the guest OS to use whatever display size you want. Fullscreen mode is also an option.

You need to install some packages before the guest additions will build. Run this in the terminal first as root…

Code: Select all

dnf install gcc kernel-devel kernel-headers dkms make bzip2 perl

Then reinstall the guest additions. reboot the guest.

install guest additions on host

Guest additions are to be installed on the guest.

I was hoping that was just a faux pas on the users part.

lol, so was i.

i think this was it. i went back to all of the random instructions i found and somehow this wasn't part of any of them. they tend to stop after Device menu, Insert guest additions, making no other guest modifications outside of what you typed. Perhaps my searches missed those that included this.

this fixed it. thanks!
