Hi, I tried Mer on my 770 this weekend. Thanks for your work, it's looking great. Some issues I had:
it freezes on every other boot for me
wireless connection was crazy but now it' seems stable with the new network manager
setting backlight doesn't actually change anything
load applet always shows max cpu consumption, and used swap isn't accurate, either (is it just for taking screenshots?)
can't use ctrl-c in xterm with onscreen keyboard

I would love to have a newer kernel with working wlan driver and iptables nat module (I also have a wsod-ed 770 and it would be so nice to use it as a wlan card/small server) .
