1. The host is using 5.2.6. I kept the guests at 5.2.4, because 5.2.6 did freeze during login or did enter a login loop dependent on the distro. I filed a bug report with Oracle and many persons had the same issue during login. The beta version 5.2.7 did solve the 5.2.6 login issues.
Today I also tried the 'beta' version of 5.2.7 with Ubuntu 18.04 with respect to maximising the window, but without success. 2. I did keep Guest additions 5.2.4 installed for all distros, but I do not remember how 5.2.2 behaved. Probably I was still using Ubuntu 16.04 for both host and guest during that time. 3. I only have the window maximising problem with Ubuntu Gnome 17.10 and 18.04, but NOT with Ubuntu Mate 17.10; Xubuntu 17.10; Peppermint 8 nor with Linux Mint 18.3. 4; That package had not been installed, but after installing that package and 1 or 2 dependencies, the system hung during reboot directly after starting the Gnome Display Manager. It looks like the bug of point 1 had been re-introduced, but now for both 3D enabled and 3D disabled. I will try to remove the package again through ctrl+alt+F2 or restore a back-up. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1748729 Title: Xorg freeze Status in xorg package in Ubuntu: Incomplete Bug description: I run Ubuntu 18.04 in Virtualbox 5.2.6 with as host OS; Ubuntu 17.10 with the propriety Nvidia driver 340 as suggested by Ubuntu. The screen almost freezes completely as soon as I maximise any window in the guest OS Ubuntu 18.04. Any mouse click takes 10-60 seconds before the system reacts to it. It took a long time to generate this bug-report. I had the same problem with Ubuntu 17.10, while Guest OSes Ubuntu Mate 17.10, Xubuntu 17.10, and Peppermint 8. Windows 7 and 10 work without any problem. WORKAROUND: Disable 3D acceleration.
