I installed Ubuntu in an Old PC and the problem is that Ubuntu is unable to detect my monitor which is Samsung SyncMaster 591s . When I go to System -> Preferences -> Monitor , There is no option to change the resolution and it is set to 800 * 600 . Which looks utterly ugly.

Here is a screenshot enter image description here

There are no options in Resolution, Refresh rate, Rotation listed in the Monitor preferences other than shown in the screenshot.

I don't have any Graphic Card installed.

Its a dual boot system with windows xp and, XP has perfectly fine resolution. Here is the output of lspci , if it helps
