1) Agreed, I will file another bug report. 2) I did already provide that information to you in the original bug- report using Vbox Guest Additions (VGA) 5.2.4. It did take a lot of time to produce it, because the system took 10-60 seconds to react to any mouse click.
Remember the problem occurs only in Ubuntu Gnome, both in 17.10 and 18.04. I tried 17.10 with VGA 5.1.30, 5.2.4 and 5.2.7. I tried 18.04 with VGA 5.2.4 and 5.2.7. I can't use 5.2.6 for testing, see the next statement on the Download page of the Virtualbox website: ------------------------------------------ Important: The Guest Additions which come with VirtualBox 5.2.6 and 5.1.32 do not work properly on Linux guests with 3D enabled. Here are updated versions for 5.2.6 and 5.1.32. ------------------------------------------ That updated version is VGA 5.2.7. -- 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: Host: Ubuntu 18.04, Virtualbox 5.2.6 Guest: Ubuntu GNOME 17.10 and 18.04, using Oracle Guest Additions 5.2.4, or 5.2.7 The problem is the guest's screen almost freezes completely as soon as I maximise any window in the guest. Any mouse click takes 10-60 seconds before the system reacts to it. I am not using Oracle Guest Additions 5.2.6 as the guest won't boot. Windows 7 and 10 work without any problem. WORKAROUND: Disable 3D acceleration. WORKAROUND: Use as a guest Ubuntu Mate or Xubuntu.
