Resolution problem in ubuntu for mac os catalina


Recommended Posts

Hi there, I started a computer science course online and for that I had to install linux's With virtualbox. At the moment it is working on a very low resolution and I cannot change the resolutions almost.

 At first I was able to change some resolutions to a 4: 3 ratio and it worked with such annoying blasts in the mouse but still worked. When I tried to change to my MacBook Resolution - 2560 by 1600 and some other resolutions it got stuck completely and I had to turn the system off and on.

The ubuntu is version 18.04.3 and I have a Pro 13 'bottle with mac os catelina 10.15.2.

Does anyone have any idea why this is happening? I have no clue about these things and couldn't find an answer online ..

Thanks in advance
