Second monitor flickery and unusable

[Alex Whitman]

After boot or after log out, my second monitor is flickery and unusable at the login screen. The mouse won't move from the primary monitor to the secondary. After login the secondary monitor works fine.

In 12.04 the secondary monitor would show a clone of the primary monitor which it could be doing currently but the screen doesn't display correctly for me to know.

lspci reports my graphics card as:

I've managed to work around this for now by using a the display-setup-script config option to run:

xrandr --output HDMI1 --off && xrandr --output HDMI1 --auto --right-of HDMI3

Closing assumed fixed. Sounds like a driver issue anyway.
