I want to install elementary OS and try it out but it never reaches the GUI the background appears for a fraction of a second and it then goes into an endless loop mouse cursor bottom right and back to a blank screen. It just keeps doing that forever. I had the same issue with Ubuntu 18.04 and it never was resolved, 18.10 is fine on the latest download. The graphics card is an ATI / AMD RS740 [Radeon 2100] built into the PC a Packard Bell UTOW-BEN. Can anyone help?
