http://askubuntu.com – Colors from graphic card gets sometime inverted. When I start Ubuntu 12.04 its just fine, but sometimes after some time the colors get inverted. I use a 40" lcd-tv as a monitor, and if I cahnge the cannel and then turn it back its ok again for some time and then it happend again. I have a "Sapphire Radeon HD5450 DDR3 HDMI 1GB" and a 50HZ SONY TV. I have a dual boot so it happens the same in my Windows 8, I have a nother computer connected to my TV and I have never had a problem like that earlier. (HowTos)

Ok …. So there is no easy way to Mod the Stock Google Browser.apk to make it easy on the eyes. Trust me I have tried, and I am a fairly good themer. Problem is, the websites determine their webpage colors. I wanted something easy on the peepers with these colors. (Black background/White text, Blue links w/Grey visited links).

I've found myself truly wondering why so many android developers don't seem to offer an inverted option for their apps. I mean, look at all the inverted apps that float around out there. I can't imagine that Google is doing it for the same reason that say, Facebook is - by that, I mean that it's a brand thing for many companies.

Just curious what everyone's opinion on inverted gapps(dark background, light text) are. I just flashed Black Bean AOKP and it's taking some getting used to. It feels waaaay different than stock somehow for me.
