Well I think this is already been asked but any of those questions did not answer me.
My computer, a HP d260 MT brand machine has the following specs:

• Pentium 4 processor @3.0 Ghz


• On-board Intel 82865G graphics controller @ 96mb


• 1 GB RAM

I have seen many telling that with their Intel 82865G graphics they are able to run ubuntu 13.04 but I tried ubuntu 11.04 on my computer last year and its desktop screen was not showing and unity was not working

Please help me.
