Hi Lee,

This works for me in Lubuntu 13.10 i386 (and is particularly useful with
old Intel graphics)

Edit (or create) /etc/X11/xorg.conf as follows: (there should be a tab
before each line except the first and the last).

Section "Device"
	Identifier "Intel Graphics"
	Driver "intel"
	Option "AccelMethod" "uxa"
EndSection

Restart X (reboot, restart your display manager, whatever). Colors are
back to the way they used to be and flash works.

Best regards
Nio
