|OpenBSD 6.2 on a Librem 13 v2|
OpenBSD is my primary OS for both servers and desktop because of the emphasis on security, standards, and a developer oriented focus. I especially appreciate the default minimal install.
Why a minimal install is an issue for me...
Security! The less stuff I've got running the safer I feel. I administer systems running several different *nixes and even a few with that monolithic monster from Redmond. A minimal install makes it significantly easier to secure and maintain systems. The nice thing about OpenBSD is that a minimal install is the default.
Intel ME -
The Intel Management Engine is disabled in BIOS.
Wireless - It's a AR9485 :-(
There are probably more posts on the net about getting these wifi adapters to work in BSD than there are cat pic sites. Atheros has been acquired by Qualcomm and doesn't seem too eager to play with the FOSS world.
“Not Configured” Devices -
Several ACPI features, thermal regulation, and some features of the Intel 100 series chipset are detected but not configured.
Console Video -
The default console video works fine and X(7) starts without any configuration. However, the brightness up/down keys on the keyboard do not work. Brightness can be set with wsconsctl(8).
External Video -
Connecting to the HDMI port as expected. You may need to tweak X(7) or use xrandr(1) to get your preferred window manager to play nice. The external video toggle function key (Fn+F7) prints "p" and does not switch the video configuration.
The touchpad is an Elantech. Tapping must be enabled in wsconsctl.conf(5) if you are not using the synaptics(4) driver.
The audio has a soft buzz when the audio system is enabled during boot. This can be easily solved by muting the speakers when not playing audio. When watching video or listening to music the buzz isn't always noticeable. The keyboard mute button works as well as the volume up and down keys.
Manual suspend and resume, as well as hibernate, all work as expected with apmd(8). Suspend on lidaction must be disabled because resume on lid open enters an infinite loop that will require you to disconnect the battery to recover.
BIOS - Version 4.6-a86d1b-Purism-5
The backslash/pipe key doesn't work as expected. It produces the < and > scancodes for some weird reason. It turns out this is easy to fix with a combination of wsconsctl(8) and xmodmap(1).
The Purism key pops the IceWM menu. The other special key generates a keycode but isn't assigned to anything useful.
The keyboard backlight toggle key works with three levels (off, low, high).
Power saving and CPU throttling do not to work. The BIOS is missing the necessary entries to allow the CPU to regulate itself. This obviously affects battery life.
Other - Color
The machine is a deep, deep matte black with no visible branding on the lid or interior. The downside to the color is that it really shows finger smudges. If this bothers you, you'll need to carry wipes with you to clean it up every time you use it.
