I just upgraded to 12.04 and have just noticed that the
tty sessions tty1-tty6 accessed via F1-F6 have a distorted graphics output whilst the GUI F7 and terminal windows within the GUI work fine.
It would seem like some incorrect resolution setting, but I do not want to risk loosing all screen output by messing up the settings.
What settings should I be looking at?
Grateful for assistance.
