The screenshot is in the link. Is there any way arroung to solve the problem or I need to re install the Ubuntu with the actual monitor plugged in while installing it. I get out of frequency error HF: 68.7 kHz VF: 85.0Hz Operating Frequency HF:30-54 kHz VF: 50-120 Hz After 30 seconds i get a black screen with the cursor blinking for some time and then the monitor shuts off.

Prepare a live usb. Try booting through it.

If you succeed do the following,

Run Boot-Repair
Click Advanced options
Go to the GRUB options tab
Tick the out-of-range option
Apply

If you failed to boot with ubuntu live disk. Prepare a disk for Boot repair ISO. This should do the work.

A live USB is not necessary. A live CD will do just fine. – nanofarad Jul 16 '12 at 17:48
