Clarification：This device is not produced by Purism, it is just because there's no such vendor (GPD) in h-node's database.

The GPD pocket 3 is a UMPC which is really powerful for an UMPC and is useful in many scenarios, AND could also work in a free software activist's hands.

Tried several GNU/linux-libre distros, most of them barely made to the desktop environment, EXCEPT Debian. Uruk GNU/Linux(3.0_beta)'s GRUB reported no suitable video mode found.PureOS reported the same. Trisquel Nabia 10.0.0.1 doesn't show anything but blank screen.

Just as expected, the screen is rotated, and will not be initiated if suspended. Just follow the tips on the internet and they will be fixed. No blobs needed.

Display seems to be fine. GLXgears shows 60FPS which is identical to the display refresh rate. The HDMI or Lightning could provide more framerate possibilities.

All the components of this computer are soldered to the board except the M.2 SSD so it's really hard to switch the WLAN card. And the default card which are AX201 (N6000 model) or AX210 (1195G7 model) have no free driver available in my knowledge.(Github may have some)

The webcam is working, which surprised me. It is running under a terrible framerate. The resolution is hardware limitation, but the low video FPS is caused by driver issues . With blobbed distros it is at least acceptable at approx. 30fps.
