Follow up to: this question:
After uninstalling a load of packages in order to free space on /boot for upgrades etc. I loaded Ubuntu software manager and was prompted to install an update, which I did, and then restarted. After restarting, the network connection is down. All settings are before, I hadn't touched
/etc/network/interfaces before, only created/edited the network settings in Network Manager.
Also, the screen resolution is wrong and can't be changed. It would appear that I've lost network card drivers & graphics drivers. I have fixed this many times before in Windows but I wouldn't have a clue how to go about it in Linux?
