    sodface,

    I know it has been a while but I wanted to let you know the 3 units I left on Alpine have been pretty darn solid for ages.

    One of them just sits as a replacement for an old custom Joggler (itself a replacement for a broken Touch MANY years ago).

    The other ones are sacrificed to the gods of tinkering for various projects, in fact one is currently working as a hugely OTT serial logging console for some dev boards.

    Thanks for coming back with an update DJWillis! Glad to hear you've had success. Are you using the onboard audio and/or internal speakers on any of them or a USB DAC?

    I used the internal speakers (with some ALSA faffing) briefly, but they are now using Topping TP30 DAC/AMPs (again, with some ALSA conf.) as that is what I used with the older setups and I just swapped out the panels and left the AMP and speakers .

    Get the odd crash of SqueezeLite that I am still looking into, but works well for the most part and I have tinkered a fair bit at this point so it will almost definitely be my fault as I was also modding things to move away from running the apps as root.

    I also started to hack up one of the old Jive Applets to turn off the screen on power off if setup as the screensaver (using /sys/class/backlight/backlight/brightness, /sys/class/backlight/backlight/bl_power), not yet working reliably, but works well from the shell directly. Ideally I want an auto backlight and off totally on power off so need to port over a script to manage that and get the data out of the light meter.

    I think I have an idea on what is wrong, permissions on the backlight being tight etc. (as it should be).

    My good lady made a mandatory request to stop backlight glow so I'll keep tinkering.

    Having a snag (of all things) is with fbsplash, considering I use it all the time in other projects I am putting it down learning Alpine.

    In simple terms, a great little platform to hack about on and most of the snags are down to me not leaving well enough alone.

    DJWillis if you have any discoveries with the backlight or anything else, please come back and post them as I suspect they will help at least me!

    >> get the data out of the light meter

    Is there an onboard light meter? I thought there was initially and said so in post #1 then I convinced myself otherwise and went back and edited it out. I'd like to be wrong about that.

    Alpine 3.15.0 was released so I updated the usb boot image using that and the 5.15.4 kernel. Made a few kernel config changes in the FAT filesystems section which maybe will help with mounting usb sticks.

    Updated links are on the Alpine wiki page and also a copy of the wiki page that I ported over to my little site on the web:

    Happy Thanksgiving to those who celebrate it!

    Still tinkering with different configurations on the Chromebase Mini. This is Alpine running the bspwm tiling window manager, touchegg for multitouch gestures, and the LMS material/mobile interface running in a QTWebEngine based browser called Weaver. Weaver windows open with no decoration whatsoever and are controlled from the command line via netcat commands. This is perfect for something like this where you want a kiosk sort of interface for material. It's not strictly kiosk though because I can still swipe and change workspaces and have different apps running. Touch works awesome.
