No - although I only need to boot to OSX once and force integrated GPU. The setting seems to remain persistent across reboots and power cycles (probably stored somewhere as an EFI variable?). Anyway, (like Seth and Matthew) I think the problem is i915 and not the gmux device. It seems to me that if i915 has no output connected during startup/module initialization it won't find one later on: e.g. even though gmux is setup correctly I get a black screen and in my X log: (WW) intel(0): No outputs definitely connected, trying again... > > No, this one is only going to get you backlight control. Actually, my patch only allows you to talk to the gmux device of MBP10,1. Only with forcing the integrated GPU in OSX and with: > [..] switching patch ([1], see patch 12), [..] the MBP works well with the Intel GPU across reboots and suspends/resumes. (With 'echo OFF > /sys/kernel/debug/vgaswitcheroo/switch' the discrete GPU can be turned off and I get an estimate of 7 hours runtime on lowest brightness settings) Also in support of that the problem is with i915 is the fact that actual runtime GPU switching works (2 times) if the MBP is booted with the Intel GPU.
