GPU not detected Ubuntu

Apologize for the late reply but in my case it was an hardware issue, my lap is Dell inspiron 5500 and after searching found that removing the CMOS battery for a while then plug it in again may help, but be aware to remove the main battery for a while first before removing cmos to cut in power running on the hardware, done this and the gpu appeared normally.
