[Resolved] Windows 10 guest : no full screen

Hi,
I'm using VirtualBox 6.0.14 on Debian 9 host.
I recently updated VirtualBox and my Windows 7 guest to a Windows 10 version.
I also took care to install the extension pack on my host and the guest additions on my guest.
Since, I can't get my Windows Guest to display on full screen.
In display settings, I picked "VBoxVGA" as graphic controller, I check 3D acceleration and I'm using 256Mo for virtual memory.
I attached the log file for my current session, hoping it could help. I had to head the first 125k to avoid exceeding maximum size.
Thanks for any advice.
have a good day.
Y.

Seems like the host window manager is blocking attempts to create a fullscreen window. What is the native resolution of the host display anyway?
That "WARNING! :resolution not accepted" message started appearing in some logs a while back. I have to admit that it still isn't obvious to me what it means, i.e. who is rejecting what, and why.

Hi mpack,
thanks for your reply and your hawk eye.
My host has a 1920x1080 resolution.
I have to admit I don't quite understand this log message either.
Anyway, I'll dig Google about it.

The guest is using the old VboxVGA video card and 3D, with the up-to-date 6.0.14 Guest Additions apparently from the ISO that came with Virtualbox. Surmise: Though the old VGA card with 3D active is not supposed to be removed until 6.1.0, could a slight incompatibility have developed in the efforts to make the new video cards? Just a guess.
Yves35, maybe try changing the guest video to VboxSVGA (note the S)? A few guest reboots and perhaps an uninstall & reinstall of the Guest Additions after the change might not come amiss.

I found useful advices on StackOverflow (not authorized to post links yet).
I solved it thanks to the following steps :
1. On VB, File > Preferences
2. On display tab, under "maximal guest screen size", I picked "Hint" and manually entered my full screen resolution : 1920 x 1080
3. Restarted VM
Fun part : I stopped my VM and rolled back these settings to "Automatic", and is still works.
Edit : it stopped working. It seems you have to keep the settings to "Hint" with your custom resolution.
Edit bis : it has an undeterministic behaviour.
Thanks for you help and efficiency.

I had this same problem with VirtualBox 6.1 on Oracle Linux 7.7 running Windows 10 v1903. Changing the suggested size under hints did not give a full screen and the left side and task bar were missing. The maximum screen size was 1024x768. I was using full screen by selecting the "maximize" icon.
When I un-selected the maximize icon and tried to view the entire window the screen sized increased as I expanded the window. I was then able to then select "maximize" to fill the entire desktop on a 1920x1080 monitor. Upon restart the full screen remained.

A maximized window is not the same as full screen. Full screen means no caption bar or frame. Use the purpose built command in the VM View menu.
