Title: vgaswitcheroo on the Macbook Pro 8,2 Status in “linux” package in Ubuntu: Confirmed Bug description: Hi By default when you try and switch graphics card on a Macbook Pro 8,2 from the ATI card to the Intel card , the screen is blanked and never turned on. This is due to the driver not knowing about the LVDS Panel mode since the machine was started with the discrete card on. This patch http://cgit.freedesktop.org/~mlankhorst/linux/commit/?id=ae7b687c2a57ec50a9d3dde7b0a80a262fdc8c8 fixes graphics card switching. I have applied this patch on the 3.9.1 and 3.8.2 upstream kernels and it fixes the issue for me. Could this possibly be fixed for S and be SRU'd for Raring? --- ApportVersion: 2.9.2-0ubuntu8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: shadeslayer 2556 F.... pulseaudio /dev/snd/controlC0: shadeslayer 2556 F.... pulseaudio DistroRelease: Ubuntu 13.04 HibernationDevice: RESUME=UUID=f6d8363f-0b01-42c3-b0bd-f859a365fd6c InstallationDate: Installed on 2013-03-05 (49 days ago) InstallationMedia: Kubuntu 13.04 "Raring Ringtail" - Alpha amd64 (20130304) MachineType: Apple Inc.
