Description spaz16 2015-02-24 10:56:53 UTC 
XStoreColors() doesn't work on Intel drivers (and maybe on some other open source drivers), but this works e.g. on nVidia proprietary drivers. I recommend to use XF86VidModeSetGamma() when XStoreColors() doesn't work.
The second thing is that SDL doesn't check XStoreColors() return code - it should return the error value when XStoreColors() fail.

Can you provide a tested patch? I don't have a setup to test this here.

Thanks!
