The small mouse pointer on the screen is probably due to your console graphic resolution setting. When you start Linux you should have a boot parameter that sets the VGA card. Evidently your current setting is for high resolution. That is fine in a GUI environment but it does not mix well with a text console. You may want/need to eliminate the use of a frame buffer, if any, and set the VGA resolution lower such as 800x600 using the boot parameter VGA=770.
Here is a link to more information.
As far as SELinux is concerned I have no idea what to do there.
