Poweroff and Suspend on model 11,4
Poweroff and suspend currently does not work on kernel 4.5.4-1-ARCH. See bug https://bugzilla.kernel.org/show_bug.cgi?id=103211 for updates and progress.
Method 2 for booting using the native boot manager.
I'll be doing this on the weekend. It will be the cleanest way to boot another OS and and it won't require you to create a new partition or generate a standalone boot.efi file (hopefully). Trusktr (talk) 19:00, 26 June 2014 (UTC)
- I gave it a shot over the weekend but without success. I'll try again this weekend. Trusktr (talk) 20:38, 2 July 2014 (UTC)
Native boot manager
Does anyone have guidance on how to boot a non-default kernel (e.g. linux-lts or linux-macbook)? Not sure what steps need to be taken.
The linux-macbook AUR package (which I maintain) explains it after installation: To get suspend working properly you must do the following:
Add disable_mode=1 to your kernel boot options. In my case I use grub so I appended this to GRUB_CMDLINE_LINUX in /etc/default/grub and then ran the following command as root: grub-mkconfig -o /boot/grub/grub.cfg
Create /etc/tmpfiles.d/wakeup.conf with the contents: w /proc/acpi/wakeup - - - - LID0
When you reboot you may have to explore the second item in the default GRUB menu for Arch Linux. I think by default GRUB will attempt to boot a kernel using the last kernel you booted with (typically just named linux).
I have the 15" 2.5GHz model. I've got the Intel GPU working with the patch, I'm going to see if I can completely power down the NVIDIA GPU because it makes the laptop unusable (bad battery life, loud, and increased heat output). I'm going to see if the trick here works, if it does I'm going to reflect that on this page. Garnerlogan65 (talk) 9:30, 25 May 2015 (UTC)
