If VirtualBox guest additions are installed the resolution can be changed. Installing gcc should be enough to get the dependencies, such as gcc, make, binutils, etc.
When you install it on VirtualBox, it's launched with the screensaver locked. No way to unlock it, like if the mouse pointer wouldn't work. Anyway on how to unlock that screensaver? --Jeancayron 18:44, 22 May 2011 (UTC)
