You cannot change your laptops graphic card.
If they are no wallpapers after upgrading to 4.4.2 Kitkat this means they might have been wiped out. You can find free wallpapers on zedge.net/wallpapers/6987/xolo-q1010-wallpapers
You can upgrade it from Intel x4500 to Nvidia 210m. You have to find the motherboard and change it. Really bad nvidia card, not worth it at all.
You can upgrade your android using the settings menu. But it depends on some models because some require you too upgrade it through a computer. Or If you have a custom ROM or custom firmware to update that you would have to use a recovery. Hope this helped:)
