I had a look to Launchpad and the bugs I found are listed here: <a href="https://bugs.launchpad.net/bugs/+bugs?field.searchtext=neomagic&search=Search+Bug+Reports&field.scope=all&field.scope.target=">https://bugs.launchpad.net/bugs/+bugs?field.searchtext=neomagic&search=Search+Bug+Reports&field.scope=all&field.scope.target=</a> But I didn't see nothing about wrong colors, just banding issues due to the lack of dithering on drivers. And Aere, did you try with a Lubuntu 12.04 live CD to see if the color are right? As far as I remember LXLE is focused to strongly support old chipsets too. Perhaps they are using some additional settings or different drivers. Let us know. F.
