Since Ubuntu 11.04 Natty, after a fresh Ubuntu installation on my desktop PC, the monitor starts into ‘input signal out of range Change Settings to **x** 60HZ’.
The problem can be fixed by reset the Grub screen resolution ratio. I used to use Startup-Manager, but ‘StartUp-Manager is dead’ it has been dropped in Ubuntu 12.04’s repository.
In Ubuntu 12.04 LTS, we can use grub-customizer to fix the problem:
- 1. Start your machine, on ‘signal out of range’ screen press Enter. Wait a second (or try Ctrl+Alt+F1, Ctrl+ALt+F7), it will boot into Ubuntu.
- 2. Once boot into Ubuntu, configure the network and install grub-customize by running following commands in terminal:
sudo add-apt-repository ppa:danielrichter2007/grub-customizer sudo apt-get update sudo apt-get install grub-customizer
Or directly download and install the deb from launchpad.net
- 3. Launch grub-customizer. In its Preference window second tab, check and change the resolution. Remember to click ‘Save‘ the configuration
