I could really use some help. Sorry in advance for long post. Friend gave me sweet 24" LG monitor, which worked when I plugged it in. Perfect resolution, etc. Then power went out or something happened and shut system down. When I rebooted monitor displayed out of range 92.9/58. Nothing I do can get past this screen. I tried holding Shift down at boot, but will not pass this screen. Only thing that works is booting from live CD, and Clicking, Try Ubuntu. When I do that, the screen comes alive and is perfect. I even open Display settings, and it has a selection that is just right. When I reboot, taking ubuntu CD out, I get that same out of range screen. I even booted with ubuntu CD, then when it opened, I went into Terminal and downloaded the most recent nvidia driver, 304.51. Said it installed. I went to nvidia-settings in Dash, and a dialog says I need to restart X server. Went to Terminal typed nvidia-settings config (something like that, can't remember), and it said something I can't remember, but about xorg file. Nothing is working. As soon as I reboot without ubuntu cd, I get out of range. Help!
Since the cause of the problem might have been a sudden power outage, I'd try checking the file system for errors. Boot from the CD again, open a terminal window and run
