I updated my Nvidia drivers via the Additional Drivers tab and the installation went ahead and installed then requested a reboot, after the reboot I lost the desktop and it instead booted to command line. So in response to this I ran these 2 commands to repair it.
sudo apt-get purge nvidia*
then reinstalled the drivers by running this.
sudo apt-get install nvidia-current-updates-dev
I regained my desktop environment after a reboot but since then my screen (Benq 27") is now shown under Displays as a Laptop and it will not detect the Benq, even though it does offer a full range of resolutions and aspect ratios.
Can someone please give me a push into the right direction please?
