virtualbox.org

Host: MacOS 10.12.4
Guest: Windows 8.1 Corporate 64bit (4Gb/256Mb video)

I can not set screen resolution more than 1024x768. Video driver do not allow to do it.
Auto screen resize after window resize do not work as well.
Screen resize via screen size request do not work.

What is wrong?

What is wrong?

You haven't installed the Guestadditions?

If Towo's guess is not enough then please post a VM log file. With the VM fully shut down, right click and "Show Log" in the GUI, save "VBox.log" (no other file) to a zip, and attach the zip here.

I'm having the same problem... Virtualbox Guest Additions is installed. I've re-installed Guest Additions several times, disabled/enabled 3D acceleration etc. I downgraded Virtualbox to the prior, working version and its associated Guest Additions but that didn't get the resolution and auto-resize working, so I upgraded back to latest/greatest Virtual box and its associated Guest Additions. Host is Mac Sierra 10.12.4, Virtualbox Version 5.1.22 r115126 (Qt5.6.2). Resolution 1920x1080 isn't available in the Windows guest generic driver. 1080p doesn't work, auto-resize doesn't work...everything was working great until a couple weeks ago. Log should be attached.

It should, but it's not

I am having the same issue, the VB will not mirror the laptop resolutions. I have reinstalled the extension pack and the guest additions with no luck. I have attached the log file.

Thank you for the help

This is not the log file. Please try again:

• Follow a "start the VM from cold-boot"/"observe error"/"shutdown the VM" cycle.
• With the VM shut down completely (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response (see the "Upload attachment" tab below the reply form).

Under View the Auto resize Guest displays somehow was unchecked (somehow = it must have been something I did:) Checking that has snapped everything back to normal.

Thanks for getting back to me on this.

Hello, I have the same problem with my Asus gaming monitor. Can you tell me briefly what do you mean by guestadditions?

User Manual, ch. 4 Guest Additions.

Hi,

I hope I'm not hijacking the thread, but I'm having the same issue - I'm attaching the log file so some guru can help me.

Thanks in advance.

Kind of, but we forgive you. Just remember, it's just as easy to create your own, private, 110% of the attention, thread.

You haven't installed the Guest Additions. You have just inserted the CD. Now from your guest you need to run the "VBoxLinuxAdditions.run" and make sure that you don't get any failures along the way.

What happens is that I'm getting errors when I run VBoxLinuxAdditions.run - I went to the /run/media/daniel and did:
sudo ./VBoxLinuxAdditions.run
and got: and the /var/log/vboxadd-setup.log.gz is attached below.
But now the screen is black.

From the file "vboxadd-setup.log":

...
/tmp/vbox.0/vbox_mode.c: In function 'vbox_best_single_encoder':
/tmp/vbox.0/vbox_mode.c:358:3: warning: passing argument 2 of 'drm_encoder_find' makes pointer from integer without a cast [enabled by default]
   return drm_encoder_find(connector->dev, enc_id);
...

This looks similar to a problem reported by "tim79" in viewtopic.php?f=3&t=86799#p434690
In there it is mentioned that there was success with the 5.2.23 GAs...

Do I have to compile the sources to get VBoxGuestAdditions_5.2.23-126769.iso or there are binaries for it?
