Title:
X server fails to start on MacBookPro9,1 with hybrid Intel/Nvidia
graphics: no screens found
Status in “xserver-xorg-video-intel” package in Ubuntu:
Confirmed
Bug description:
I have a MacBookPro9,1, which has both an integrated Intel HD Graphics
4000 controller and a discrete Nvidia GeForce GT 650M. I want to
disable the Nvidia graphics and boot using Intel only, since I don't
need the Nvidia chip's capabilities and it shortens battery life (and
makes suspend/resume not work; see bug #1084960). But when I
blacklist the Nouveau driver and reboot using the Intel driver only,
the X server fails to start: it reports "no screens found" and
crashes.
I'm booting using EFI rather than BIOS; not sure whether that's
relevant.
I'll attach the X server log and the dmesg log. Just let me know if
there's any other information I can provide.
