Virtualbox and Linux Mint high CPU

change ubuntu linux mint from cinnamon to mate

I use VirtualBox a lot. Mostly on Windows 10 host and Linux Mint guest (Ubuntu, Linux Mint 18). And it was always horribly slow no matter what cpu/memory/video acceleration settings I used. If using without “3d hardware acceleration” it was just generally slow but using the hardware acceleration was sometimes glitchy and most of the time very high CPU usage reported in htop. Today I finally found a solution – install MATE desktop interface in the linux virtual machine! Turns out Cinnamon interface that comes default with Linux Mint heavily depends on graphics acceleration and Virtualbox just cant do that even with the Guest Additions Iso. Mate desktop interface uses only CPU and in a very efficient way – finally the Virtualbox virtual machine feels like real OS and is real fast, CPU usage went from 10-80% to 0-1% idling.
To switch Linux Mint from Cinnamon to Mate:
1. open terminal, type “sudp apt-get install mate-desktop”
2. log out of cinnamon
3. on login screen click the upper right corner of login box and choose Mate
4. log in and enjoy!
