I was on my laptop, and I decided to use my external monitor to enlarge the screen. It wasn't showing the display, even after I pressed the detect displays button. So I followed the instructions on this website: Ubuntu 16.04LTS extended display not working and I followed the steps. On the last step, I had to do the command
sudo apt-get install nvidia-364
and it showed me this:
Reading package lists... Done
Building dependency tree
Reading state information... Done
N: Ignoring file '50unattended-upgrades.ucf-old' in directory '/etc/apt
/apt.conf.d/' as it has an invalid filename extension
E: Unable to locate package nvidia-364
I don't know what to do now because I don't have the nvidia-364 package. Can anyone help me?
Thanks, Vaibhav
P.S I have a Ubuntu 16.04 Lenovo Thinkpad.
