I've installed Kali linux on a couple of machines before, which was absolutely fine. I'm trying to install it on a PC without a IGP (i5 3350P) but WITH a dedicated GPU (amd 7870 XT). The installation goes fine, not a single error, but when I boot up it proceeds the first screen, but after that it goes white and 10 seconds later it starts showing weird stripes on the screen (http://i.imgur.com/CyQU2Cv.jpg).
I included an imgur link because the upload/attachment manager on the forum isn't working for me.
I think it might be an issue that it won't run of the IGP and doesn't recognise the dedicated GPU? I've run kali on the same system but in a VM which worked fine, but probably doesn't rely on the IGP.
Does anybody know what the issue is? It's really hard to find people with the same issue because it's such a vague description as well.
Thank you in advance!
