Hi, I'm on KDE Plasma x11 and since the recent updates I can't get auto-sized feature to work with my guest OS Mint MATE, but instead - it always opens as a small fixed window 800x600px (completely ignoring the fact that the guest window is actually maximized on my 1920x1080px screen).

Each time I have to run inside my Guest OS in order to auto-size it properly. Is there a way to automate this when starting the Guest OS, as it worked fine about two months ago?

Settings: This is how my guest OS loads: Thanks!

Such a command is not necessary when the Guest Additions are working properly.

Start the VM from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the VM from within the VM's OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Right-click the VM in the main Virtualbox window's VM list, choose Show in Explorer/Finder/File Manager. In the "Logs" subfolder, zip the VM's "vbox.log", and post the zip file, using the forum's Upload Attachment tab.

I just fixed it.

I always start the VM from full normal shutdown.

Zipped log is attached below.

Very old Guest Additions to try running 3D acceleration. Better to have them closer in version if not up-to-date.

However, 7.0 has just come out of beta and is still going through growing pains. 7.0's Guest Additions are particularly affected atm. I'd try 6.1.40's GAs https://download.virtualbox.org/virtual ... 6.1.40.iso.
Linux VMs have prerequisites for installing GAs, see https://www.virtualbox.org/manual/ch04. ... ions-linux and https://www.virtualbox.org/manual/ch02. ... nux-prereq

That did the trick, now it works great, thank you!

Great! Glad you're up and running.
