Switchable graphics computers
-----------------------------
Computers with switchable graphics (such as Optimus) fail to choose a
video card and end up on a black screen. This has been reported for
MacBook Pro 6,2, MacBookPro10,1 Retina, MacBook Pro 15-inch early 2011
and might affect many others.
There are two possible workarounds for this issue:
* It is possible to force the computer to start with the integrated
GPU only, for example using a third party application,
http://gfx.io/, to force integrated only through OS X, and then
reboot in that special mode that works with Tails.
* It is also possible to make it work by booting with `i915.modeset=0
rootpw=pass` (and then changing the root password once the computer
is started) and drop a file containing:
Section "Device"
Identifier "Device0"
Driver "nouveau"
BusID "1:0:0"
EndSection
and restart X with `service gdm3 restart`
