I have used Oracle VM VirtualBox to load Ubuntu 11.04 on my computer. But the problem is that I cannot open it up full screen. The highest resolution I can bring it up to is 1024 x 768. My current Windows resolution is 1680 x 1050. I have a Samsung SyncMaster 226BW monitor. My video card is an ATI Radeon HD 5570.
I’m sort of new to Ubuntu, and I want to learn more about it, but I really want to bring it up to full screen size within the Oracle VirtualBox. Can I do it? If so, can you tell me how to do this?
