The problem is basically 'ubuntu 15.04 will install - but wont work' unistalling will fix the problem, given the chance I could have edited the answer to include 'and install 14.04 or other linux system that will work well with the hardware available'.

@Fabby I still have 15.04 on a HDD partition, it broke during an upgrade and i cannot fix it because everything i tried failed. So now its just storage space and Im currently using Kali 2.0, without a single problem yet..

@muru I didnt say reinstall .. I said uninstall.

@muru the OP said 'After weeks of struggling with various black/purple screens'. After weeks of a system not working and multiple installs of previous versions and new installs its not worth all that for Ubuntu 15.04 which is not that amazing anyway.. I like ubuntu .. just not 15.04

I defo feel like low rep users are disrespected on askubuntu, its making me dislike being on this site tbh.... :( If i come to ask a question now all im gonna think is 'whos gonna jump on me now?' 'am i gonna be banned any minute for asking questions on a q&a site.... not feeling comfortable here

I felt the better option would be to uninstall 15.04 as it really does suck! Its a fair answer and it was different to other answers, it would be an option for the OP.

@fabby If the 'car' is a piece of junk then answering 'get rid, its a piece of junk' is a good answer, it relates to the question, its better than saying waste your time, money and life fixing a 'piece of junk'. The OP for (askubuntu.com/questions/623367/…) doesn't actually ask a question!! which is against the rules.

I'm confused, I followed the basic rules. My answer is a fairly good quality answer.
