--- Comment #33 from Sandeep sandy.8925@gmail.com --- After poking around a bit, I found out that I can re-enable the LVDS display using KDE's display settings (which uses xrandr), so it's just that the display isn't turned on by default for some reason (even though it was being used before suspend)
