Hi guys. Need a bit of help on this one. I am using a dual boot system with Windows XP Pro and Ubuntu 8.04 (Hardy Heron). Ever since my video card (nVidia XFX 7600 GT) conked out, I'm stuck at a screen resolution of 800x600. The only other option that is available is 640x480. Is it that the system requires a video card to push up resolution or am I yet to uninstall a particular driver? Can't figure it out. Thanks in advance for any help.
