The Sony VAIO PCG-F540 has a video card from NeoMagic (MagicMedia 256AV+) that seems to be fully supported by Ubuntu 13.10: http://manpages.ubuntu.com/manpages/saucy/en/man4/neomagic.4.html if the display works fine on 12.04 live CD without any additional parameter then you probably need to open a bug report against xserver-xorg-video-neomagic. I had a look to Launchpad and the bugs I found are listed here: https://bugs.launchpad.net/bugs/+bugs?field.searchtext=neomagic&search=Search+Bug+Reports&field.scope=all&field.scope.target= 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.
