Lenovo ThinkPad X1, Sandy Bridge (Core i5, 2,5 GHz), NWG2MRT This model has SSD 80/HDD 320 pair. Comes without optical drive. Has UEFI BIOS with BIOS-legacy fallback mode. Has Windows 7 Pro pre-installed, with tons of bloatware (bing toolbar, big Lenovo superbar button et all) pre-installed, too.
Drive space customization
- SSD: two WinRE partitions and one Windows system partition - HDD: blank
I've chosen to:
- leave WinRE untouched (there are two such partitions) - use SSD for my root partition - use HDD for swap, /home, /var (~30 Gb, pacman cache goes here), /tmp
Due to the fact that there is no optical drive, you need to install Arch from USB stick.
The lazy way to install is just default installation, works flawlessly. Installed system will boot in legacy-BIOS mode.
Download the official ISO or create your own using something like Archiso. Follow the instructions for creating a UEFI bootable USB from the ISO. Note that the default bootloader works fine so there's no need to replace it with an alternative like rEFInd. In the BIOS under Startup, set "UEFI/Legacy Boot" to UEFI only and turn off CSM support (this step might not be necessary, try skipping it first if you like).
Upon saving your changes and restarting, the UEFI boot options from the USB stick should come up and you can proceed to installing Arch.
It appears that the default partition table (and Windows installation) uses MBR. To use UEFI, you should reformat the disk as GPT (wiping the drive in the process). Follow the instructions for creating the EFI system partition.
gdisk recommends a size of 300M. Follow the Beginner's Guide to see how to correctly generate (and then fix) the fstab entry for the ESP.
Booting using an efibootmgr entry is quite simple (and doesn't require any extra packages). Simply follow the instructions for creating the EFISTUB and adding the efibootmgr entry. The note about Lenovo Thinkpads truncating the UEFI options doesn't apply to the X1: the recommended efibootmgr entry works fine. The note about escaping the backslashes in the initrd path does apply, verify with
efibootmgr -v that the boot entry doesn't have any missing characters.
Almost everything works out of the box. Install synaptics and video-intel drivers.
Tp_smapi does not seem to work at all.
Suspend works fine, even with status indicator.
The only special keys that seems to work out of the box are the sleep, wifi, and keyboard backlight keys. All of the others (volume, brightness, etc.) need to be mapped using something like acpid. Here are the relevant acpi events

I had no luck getting an acpi event for the microphone mute button.
I will improve this page after several days using this laptop. Today is my first day of it.
