More than smartphone, not yet laptop: Swmo on the PinePhone Pro

I’ve been daily driving the PinePhone Pro with swmo for some times now, it’s not perfect but I still find it be one of the most enjoyable devices I’ve used. Probably only behind BlackBerry Q30/Passport which also has a decent keyboard and runs an unfortunately locked-down version of QNX. For me it’s less like a phone and more like a portable terminal for times when using a full size laptop is uncomfortable or impractical, and with the keyboard it’s possible to write lengthy articles on the go. ...

Linux, sync, git-annex

git-annex(1) is a versatile and cross-platform tool build on top of git, it can sync, backup, archive files and provides many useful primitives for building customized workflow and storage system, for example, by combining git-annex with gcrypt, it’s possible to fully encrypt data stored on a remote. Partially due to its versatility, it has a steeper learning curve than some other tools in this field and it took me some time to figure out how to make it work for me, here is a quick guide that documents my journey. ...

Basic Setup # All the tools we need for running VM are already packaged on Mobian, to install them, run: sudo apt install virt-manager then add your user to the libvirt group: sudo adduser mobian libvirt Reboot and then run virt-host-validate, it should indicate /dev/kvm exists and is accessible. Trouble with Heterogeneous Architecture # Trying to start qemu-system-aarch64 with -enable-kvm flag can yield the following, rather unhelpfully worded error: ...

A week with Mobian on PinePhone Pro

PinePhone, Mobian, Plasma, Linux

It’s been a bit more than a week since I start daily driving the PinePhone Pro with Mobian, some parts of my journey are documented here. IME and Keyboard # Both Phosh and Plasma provide their own work flow for setting up IME and adding extra language support, but so far I’m unable to get Phosh’s ibus-based input system to work with PinYin when using on-screen keyboard. I’m able to install PinYin and Anthy from Phosh’s software center, but those methods only work when used with external keyboard, switching to either of those from on-screen keyboard makes no difference when typing. ...

Setup Tow-boot # Mobian as of now requires Tow-boot bootloader to be installed first, u-boot is no longer supported. To install Tow-boot, see this document, I find it easier to plug in a usb cable to start the phone while holding down the RE button. Be mindful that there will be no graphical boot menu after installation, at the moment tow-boot menu is only available via serial connection. It’s also possible you can skip this step, according to the PinePhone Pro wiki: ...
