Hi Aere,

1. Does it work for you with UXA acceleration (for graphics and video)
according to this method?

Edit (or create) /etc/X11/xorg.conf as follows: (ugh, can't format,
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.

2. The problem with audio is new to me. If you have the time, please
report it as a bug at launchpad.

Best regards
Nio
