I am using an external monitor for my laptop to run Ubuntu with. I just updated Ubuntu today, but when it is about to reach the Ubuntu login screen, then the monitor says "out of range." Now, Ubuntu boots up into the GUI if I unplug my monitor and use my laptop screen, but I prefer to use the external display. I have tried all of the suggestions from my search results in Google.
I tried pressing Ctrl + Alt + +, but nothing happens. I tried pressing Ctrl + Alt + -, but nothing happens.
I used Ctrl + Alt + F2 to get into a terminal to run the command:
sudo dpkg-reconfigure xserver-xorg
but nothing happens. I believe there are supposed to be options to change the settings, but it does not even give me any.
I tried to edit
/etc/usplash.conf and /nano/etc/usplash.conf, but they do not exist.
sudo apt-get update and
sudo apt-get upgrade hoping that it would install drivers or something to help my situation, but they did not help.
My monitor is a Westinghouse 22" LCD with resolution 1680x1050. It has been working for the past few months until I updated it today.
