pressure mark

The trackball can press against the screen when the lid is closed, causing a small mark to appear on the screen.


Lid, screen bezel, keyboard frame, and wrist rest are made from milled aluminium. Side panels and transparent bottom panel are made from acrylic.

Screws in the LCD bezel are not covered, and over time the one in the center can start to rub the paint off of the wrist rest.

fabricate new side panels - forum thread

My friend kindly sent me a pair of metal replacement side panels. First I tried painting them with a paint brush and a bottle of Vanta Black. This flaked off easily, so I sanded them down and repainted them with black spraypaint (satin finish). Managed to chip that as well during installation. I don’t know what I’m doing.

laird wifi antenna - improved reception

2022.04.27 Update: I ended up just stretching the original molex antenna down under the trackball, which improved reception even more than buying an expensive new antenna. Because of its shape and the orientation of its cables, the Laird antenna wouldn’t quite reach.

audio in linux

fix for speakers too quiet:

    By default, the speaker output of MNT Reform is a bit quiet, and
    changing the volume with PulseAudio won’t dramatically change it.
    There’s one more knob you can turn up that is only accessible via

    Open a Terminal and type alsamixer.  Then press F6 and select
    the wm8960-audio card.  Navigate with Cursor keys to the Playback
    slider and turn it up

Well, there is no wm8960-audio listed on my system, only (default). And Master is already cranked to 100. Investigating, I noticed:

   sl@reform:~$ dmesg | grep 8960
   [    3.613559] wm8960 2-001a: Failed to issue reset

edgineer says:

    Usually a reboot gets the audio going for me if I see failed to issue
    reset (happens on booting from power off).  Lukas speculates on a fix
    here[1] and another person[2] provided this line in order to rebind the
    device without a reboot:

          echo 2-001a > /sys/bus/i2c/drivers/wm8960/bind

    I was able to replicate the issue and test the above line out just
    now.  I had to “sudo su” first.  Then the audio device showed up in
    alsamixer again just fine.

This worked for me, as well.

Update 2022.06.20: After numerous updates, sound no longer works for me in Alpine Linux.
