CAUTION:

I am posting this ticket for information purposes, to save time of people who have "nomodeset" kernel parameter in their grub.cfg

2 weeks ago "Auto-resize Guest Display" and "Seamless Mode" worked fine, but last week something has changed. I could not pin-point the source of problem for couple days, I remember I installed ubuntu updates as usual and after starting VBox the next day both modes became grayed out in "View" menu.

I tried to solve the problem using tips found on VBox forums:

1) Installed new VBox with guest additions - it did not help.

2) I set "Maximum Guest Screen Size" to "Automatic" in File > Preferences ... > Display tab - it did not help.

3) I tried to trigger the guest system to switch to a particular resolution by sending a video mode hint using the VBoxManage tool.

I opened cmd.exe in Windows and did the following:

cd C:\Program Files\Oracle\VirtualBox\

VBoxManage.exe controlvm xubuntu-18.04.1-amd64 setvideomodehint 1920 1080 32

but inside VBox.log I saw just a single event:

VMMDev: SetVideoModeHint: Got a video mode hint (1920x1080x32)@(0x0),(1;0) at 0

of course guest screen resolution did not change.

4) Finally I set the GRUB_GFXMODE to 1280x1024x32 in GRUB and booted ubuntu, the guest screen became big enough to work on it, but "Auto-resize Guest Display" and "Seamless Mode" still did not work.

I started GRUB in commad-line mode to see what video modes (resolutions) are supported by graphic adapter:

grub> hwinfo

or

grub> vbeinfo

From available modes I choose 1280x1024x32

Then I booted the ubuntu and created a new grub.cfg:

# vim /etc/default/grub

GRUB_GFXMODE=1280x1024x32
GRUB_GFXPAYLOAD_LINUX=keep

# grub-mkconfig -o /boot/grub/grub.cfg

at this moment I noticed that I have "nomodeset" kernel parameter in GRUB_CMDLINE_LINUX. After removing it and recreating grub.cfg I booted ubuntu one again, when Xfce login window was displayed the "Auto-resize Guest Display" and "Seamless Mode" menu item become available.

#18408 fixed Exiting seamless mode does not revert guest display back to previous resolution -> fixed after (not in) 6.0.4 and in test builds thoms
Description

In prior VBox versions (< 6.0), the behaviour when exiting from seamless mode was to revert the guest screen resolution back to its previous settings immediately before entering seamless mode. In 6.0.4 (and possibly 6.0.0 and 6.0.2 -- did not test), when exiting from seamless mode the guest screen resolution is set to full-screen, effectively forgetting the prior resolution settings.
