Why don't hotkeys work in Unity3d on Ubuntu?

Question

linux

Installed the Unity3d game development program in Ubuntu. To manipulate objects in the unit, the mouse is used with the shift keys held down, but in Ubuntu this key combination does not work. Under Windows everything works. I understand that Ubuntu intercepts pressing hot keys and they do not reach the program. Tell me how to fix this so that all key combinations work in Unity 3d under Ubuntu?

Answer 1

At least because officially Linux for the unit goes like this, "in between times". It's good that it works at all)
By the way, unity hotkeys also periodically fall off in Windows - so don't whine)))

Answer 2

because everything except lts by default with glitches
you want to work norms use lts
