Ubuntu MATE 21.10 for GPD Pocket 3

In what has become something of a tradition, the Ubuntu MATE team have released images for the GPD Pocket 3 modular handheld PC. Many thanks to the team at GPD for providing sample hardware for us to work with!

Tweaks for the GPD Pocket 3:

All the hardware in the GPD Pocket 3 works with a modern Linux OS, but some configuration tweaking is required to deliver an optimised “out of box” experience. Here’s what we did:

• Enable frame buffer and Xorg display rotation.
• Accelerometer support for automatic screen rotation.
  • Also automatically rotates touch screen and stylus (draw and erase)
• Enable fractional scaling by default
  • Results in an effective resolution of ~1280x800 to make the display panels easily readable.
  • Simple to toggle on/off via the Display Scaler app if you want to restore full resolution.
• Enable audio via the HDaudio legacy driver.
• Suspend is implemented via s2idle
  • A temporary workaround until S3 sleep state is supported.
• Enable scroll wheel emulation while holding down the centre trackpad button.
• Enable Tear-Free rendering by default.
• Enable double size console (tty) font resolution.

Sadly, no support for the fingerprint reader. AFAIK only USB fingerprint readers are supported in Linux.
