@ijonglin I've put together a hardware workaround by using a 2.4GHz wireless keyboard and adding an OTG adapter so that I can have a wireless keyboard (just not through bluetooth). But still wondering if there's a cleaner solution.

Recently installed Ubuntu Touch on a Lenovo Tab M10 HD (2nd Gen) 4GB/64GB. Works very nicely, and initially connects to Bluetooth keyboard. After being idle or put to sleep, the keyboard is shown to be reconnected, but doesn't work at all.

Using rfkill and restarting the service do NOT help, but rebooting the device will "reset" the problem.

Anyone have a progamatic/script workaround to cleanly restart bluetooth services on this device?

After a really awesome Pixel 3A XL install, I wanted to get a native Linux device on a Tablet. After trying to install everything on a $50 Lenovo Tab M10 HD (2nd Gen) , but 2GB device, I finally figured out that I needed to a $90 4GB device. Then everything ran smoothly.

My primary use is a portable Linux-based spot for portable writing kit in LaTex and rendering PDF to a eReader, and after figuring out the Lomiri construct of chrooted environments, I was off to the races.

Rock solid:

• Install (once I had the right device)
• Wifi Connectivity
• Terminal and Lomiri envs and their fakeroot apt installs
• Support for USB devices (Hubs, USB Sticks, USB Mouse Keyboards)
• Support for SD Card (64GB is currently working after formatting on the system)
• PDF Viewing
• Music Player
• Audio Jack Output
• Video Player
• Sleep/Wake
• Battery usage is reasonable for a "refurbed" device

Would like to have:

• Bluetooth support works on start-up, but goes borked when the device falls asleep. A reboot solves this problem, but it's not a blocker since I'm switching to 2.4Gz wireless keyboard dongle.

Overall, I based a very portable open source writing kit. Really incredible work as good as when I install YellowDog Linux onto my Powerbook G3. A second donation was in order, but I think I got what I need for my writing kit. Would be nice to have the bluetooth working solidly -- the Pixel 3a XL Bluetooth is rock solid.
