I think it will be better to go back to your Ubuntu + Kodi setup, if that works for you. Support for AMD/ATI graphics within LibreELEC (and formerly OpenELEC) has not always been a joy. Even today it seems like a lottery.Your laptop has a ATI Radeon Xpress1150 graphics card, which is... pretty old in computer days. It has no hardware acceleration whatsoever, and perhaps the OpenCL/GL support in LibreELEC for it is also limited, hence the lonely blinking cursor.
Ok, it's a shame. I Install OpenElec (Version 7.0.1) this morning and it runs really well. It's a shame I can not use this one because this has kody kripton, thanks anyway.
