Evening everyone, loving life with Ubuntu mate 20.04 on my P50, very smooth UNTIL I decided to fire up a few virtual machines in VBox. With a 4k screen, the guest comes up microscopically small and I have not found a good method to increase the scale without dastardly side effects to the main desktop. Any kind advice would be appreciated. On a side note, when connecting a 1080p second monitor, the interaction between resolution hunting and the main screen makes both go bananas unpredictably. Fonts, window sizes, you name it, crazy. Unplugging the second monitor and we stabilize, but frequently will not restore to intended settings for the main monitor until a reboot happens.

Did you install guest additions?

Afternoon, thanks for the reply, yes, the additions are installed, but the vm spawn directly in the middle of the screen in the workspace and can not be moved from there, nor can the resolution seem to be altered.

Some distro's have guest additions and the first update after installing it usually fixes it.
Some issue with guest additions I think. Make a new test vm maybe of Ubuntu latest standard iso, update, and try it.

Evening everyone, well, naturally I stumbled on something similar in another forum and did some digging. It seems that middle button is somehow getting hung in focus for the guest OS window causing it to appear frozen. Could be a bug, who knows. One click forces the focus off and the window is then movable again. This also clears up the inability to use autoscaling win win. Thanks to the folks checking in on this one.

kind regards,
Bob
