[h1]OS Tested[/h1]

[h2]Debian 8[/h2]

[p]Tested with Debian 8, which is in "testing" as of 2015 March 16.[/p]

[p]dmesg log for wifi firmware loading:[/p]
[code]
[ 1.578731] iwlwifi 0000:03:00.0: firmware: direct-loading firmware iwlwifi-7265-9.ucode
[ 1.578969] iwlwifi 0000:03:00.0: loaded firmware version 23.214.9.0 op_mode iwlmvm
[/code]

dmesg log for bluetooth firmware loading:
[code]
[ 4268.531230] bluetooth hci0: firmware: direct-loading firmware intel/ibt-hw-37.8.10-fw-1.10.3.11.e.bseq

[/code]

[p]These work out of the box: 2.5" SATA hard drive, M.2 SSD drive, SD card reader, Ethernet, USB device passthrough in KVM via VT-d, built-in speakers, built-in microphone, headphone jack, VGA port, USB ports, suspend/resume, ability to read the status of the two PowerBridge batteries, function row keys (speaker/microphone volume control, display brightness control, and radio toggle).[/p]

[p]3D graphics requires a sufficiently new graphics stack. The packages in Debian testing [i]almost[/i] work--you also need "xserver-xorg-video-intel" version "2:2.99.917-1~exp1", which is currently in the "experimental" distribution.[/p]

[p]The Trackpad (i.e. the touch-sensitive pad below the keyboard) works out of the box; the synaptics driver can interpret multitouch gestures. Depressing the bottom left and right corners produce left and right mouse button clicks.[/p]

[p]The Trackpoint (i.e. the red nub in the middle of the keyboard) partially works. The nub itself can move the pointer, but the three buttons (located between the spacebar and the Trackpad) that complement the nub do not. This is described here: [a]http://who-t.blogspot.com/2015/01/lenovos-x1-carbon-3rd-touchpad-woes.html[/a][/p]
