I did a dist-upgrade to Bionic Beaver recently. The version of VirtualBox has gone to a newer version since that upgrade. I noticed some bugs that have been discussed on this site already but I could not find a solution yet. Because I use VirtualBox professionally and I have several customer computers simulated in a box, I want to downgrade to a lower version of VirtualBox to be able to continue work.
- The menu in full screen disappeared, I need to leave full screen before I can minimize the box.
- The mouse freezes, Leaving full screen mode and going back to full screen handles that.
- Full screen does not work properly with multiple monitors. I cannot change the monitor used for fullscreen mode.
As you can see, I have found a workaround to continue work but I find it annoying to work like this.
I have decided that I want to revert to the older version but I have simply no idea what version I was running on my old system (Xenial). Also what is the best way to get the old version back and avoid the upgrade to 5.2 on the next update.
