Distro resources

Archlinux

Amazingly the X1C3 works out of the box on Archlinux. Only a couple of niggly issues remain:

• HDMI sound output does not work
• Trackpad is a horrible UX
• Resources for running with Archlinux

Debian

Debian Jessie worked out of the box via the Ethernet connection and a netinst image on USB. All buttons appear to work. Need some more time to test but amazing. Did install the non-free firmware and repos. Confirmed that HDMI audio does work however I had to configure the HDMI audio source to be higher in the list to be selected for output. ArchLinux above should work with proper settings.

Ubuntu

Ubuntu 14.10 on ThinkPad X1 Carbon 3rd Gen
