Hello all, while I don't like OsX and have been "linux power user" for over many years, I was offered a new MacBook pro 15" (non-retina) as an upgrade for the old work laptop (edition summer 2012). Using Fedora as main OS I immediately suspected this choice was not ideal, but the build quality and hardware was tempting so I accepted the offer, well aware I'd have to work a bit to get Fedora running on it. Also very rarely I need to test some things on OsX so being able to dual boot in it sounded like a good idea. By following some guides I installed rEFIt and managed to install Fedora 17 initially, but that was a disaster of workarounds needed to apply as kernel parameters and never got it stable, so I ended up installing beta1 of Fedora 18.. much better: after yum updating to the latest kernel packages I noticed I don't even need dirty tricks such as disabling apic: the system is stable for desktop usage. There are still plenty of problems to solve for "on the road" usage: - if I try to suspend it, it can't resume -> have to cold-restart it. - booting up is extremely slow, rEFIt seems to search for a long time before handing over to Grub - when using out of the box parameters, the battery doesn't give you much more than 30 minutes work time All these combined make it damn hard to "quickly check something". After using powertop I can get it to roughly 1,2 hours, better but clearly something is wrong yet. I'm suspecting the NVIDIA card: if I run lspci it reports a single VGA device from NVIDIA; I'm pretty sure that this laptop has an intel one as well and is supposed to activate NVidia only on demand. I don't actually need dynamic switching, I'd like to disable the Nvidia one and use the Intel one only; I'm not even sure what X is using today: /var/log/Xorg.0.log mentions VESA .. looks strange to me as Gnome3 is succesfully working with all effects. My suspicion is that I'm not booting the system with EFI and the damn thing is emulating the BIOS mode as it would do for Windows installations (through Apple's bootcamp), this might explain why the Intel device is "hidden"? Looking at >top I can also see that gnome-shell is burning a hell of CPU, is that how I'm having the full effects experience while running on VESA? I see gnome-shell using around 50% of *each* of my CPUs. In my experiments I also tried to use nuoveau or the Nvidia proprietary drivers, to see if they could improve either CPU or battery. nouveau: it doesn't seem to load the modules. NVidia: system locks up booting from self-built kernel 3.8.0-rc2 (to try newer nouveau): system boots, Gnome3 shows a useless error "something went wrong, contact your sysadmin".. no clue so I abandoned this path (of course this could have failed for other reasons). As resuming from suspend also fails because the screen doesn't turn on again, I hope all these problems are related. Anyone has a clue please? As I'm suspecting it's using the BIOS emulation (how to check??), I'd like to try booting it as a "real EFI" OS but I have no clue of how that would work, and couldn't find much literature on this subject, at least not suitable for my level of skill.. any pointers appreciated, especially to work with Fedora 18!
