After trying Mint 5 LiveCD, I'm giving it an extended test run in a VirtualBox, to understand how things work for a while before committing to an install.
It seems that while my laptop has a native resolution of 1024x768 @60Hz (which the Live CD detected properly), within VB, it only sees the capability of 800x600. I've gotten around this with other distros in the past (including Ubuntu) by going to the display settings, declaring that my monitor is a 1024x768 LCD, and I'm good to go.
I've poked all around Mint 5, but can't find a similar menu location, nor could I find answers in the User Guide or Wiki. I know it must be there, so if you could point me in the right direction, I'd greatly appreciate it.
