I’m having this problem for two machines, currently I have to use
nomodeset in grub to get into live desktop.
Machine 1 is a desktop running a I7 3770k with Sli Gtx 770s, nouveau does not like my cards and am forced to use
nomodeset. I wish in the grub menu there was a way to select nvidia or nouveau packages if the user still wants to use display drivers.
Machine 2 is a laptop running a I5 (Second generation not sure exact model), with HD 3000 graphics. When the Antergos splash screen is supposed to show after the grub menu its a pure white screen. It eventually stalls trying to load into the live desktop,
nomodeset gets me into the live desktop but the splash screen is still pure white.
