@justmy2cents, thanks for the encouragement.
For the record;
Open a command line shell
#installs arandr - a GUI to help you write a screen config file.
Code:
sudo apt-get install arandr
Use arandra to create a screen configuration file. Save the file to somewhere accessible. I used /home/me/.screenlayout/myscreen.sh - I think you may need to make it executable as well with chmod +x
If using lightdm , from the command line
Code:
sudo nano /etc/lightdm/lightdm.conf
Add the following lines in the [SeatDefaults] section
Code:
display-setup-script= <full path and name of file created with arandr>
session-setup-script= <full path and name of file created with arandr>
This hasn't entirely solved my issue but it does configure the screen resolution just before the log in screen, meaning that for the session and user session the screen resolution is likely to be useful.
Cheers.
Then open a command line shell:
sudo
