I can get into installation mode just fine but live mode gets stuck, if I wait a while the splashscreen disappears and the screen goes blank.
I’m using a Dell Inspiron laptop with a I5-3210m processor and a gt630M gpu.
Same usb stick works fine on another laptop.
It seems you have two graphics cards.
Can you check if you have the same output in live and installed version with this documentation.
Also you can try to use vga_switcheroo but so far we didn’t succeed to make it works.
Ooo thanks, I disabled the vga-2 output and it worked, both in live mode and install.
Now the problem is that it seems to be using the integrated gpu instead of the discrete one, i played around a bit with that vga switcheroo thing and it didn’t work 
No errors or anything.
