Hi all. I have a laptop with switchable graphics (Intel HD 4000 and AMD 8600M). When I try to boot to graphical installer using the minimal ISO I get the message:

xauth: file /home/antergos/.Xauthority does not exist (this error x2)

waiting for X server to begin accepting connections
.. (and it keeps adding 2 dots infinitely).

Using the standard iso booting stops abruptly without an error.

I tried using radeon.modeset=0 or 1, playing with acpi, etc. Any ideas?
