This is probably a duplicate question, but i'm not able to find an answer that i understood. I have just installed Ubuntu on VirtualBox in WinXP. I'd like to improve the screen resolution to 1280x800 (which is what my host OS uses), but the settings only show up to 1024x768 in Monitors (also it shows Unknown Monitor).
Thanks for any help,

Thanks Uri, that worked. There is an option under Devices (VB menu) to install the Guest Additions. – rajath May 8 '11 at 6:50
