Graphical Interfaces

Interface Info Recommended
none works, but 'postmarketos loading...' stays around with distorted graphics pmaports#280 Y
[1]Hildon Hildon ist not available for armhf architecture. As the device is armv7 this has to be changed and we can try again. N
[2]i3wm works, but as you have no hardware keyboard, you cannot use it so far (chance to get it work on touch only devices too) N
Kodi fails to boot (rootfs not found) N
[3]MATE works fine, suitable for dogfooding Y
[4]Phosh does not show up after 5 minutes, if this kernel has no DRM-Support, Phosh won't work, have to be checked N
[5]Plasma Mobile can not build for armhf architecture. As the device is armv7 this has to be changed and we can try again. N
Plasma Mobile Extras can not build for armhf architecture. As the device is armv7 this has to be changed and we can try again. N
Shelli works somehow but has distorted graphics N
[6]Sway cannot boot at all (possibly missing hardware acceleration), simply reboots after some time, maybe that's the known bug. pmaports#248 N
[7]Weston works fine, suitable for development Y
[8]XFCE4 works sometimes but I experienced some issues, reboots some time, maybe that's a known bug pmaports#248 and freezes at boot (maybe also known)pmaports#250 N
Matchbox Matchbox once worked, but was removed from postmarketOS N


$ pmbootstrap install

Full disk encryption currently doesn't work on this device, so it should be turned off for now.


Ensure that the USB cable is disconnected, then hold down Volume Down + Home for a few seconds as the system boots. This puts the device in flash mode. Once in this mode, enter

$ pmbootstrap flasher flash_rootfs

to install the rootfs. Once this is finished, put yourself back into flash mode and enter

$ pmbootstrap flasher flash_kernel

to flash the kernel[9].


Here is a list of tasks that are currently being worked on for this device, from highest priority to lowest.

Bluetooth is likely an external chip: "Bluetooth 4.0 (external WCN2243); 802.11b/g/n (external AR6003/5, WCN1314)" WiFi is likely as well, but camera support is integrated.

According to some websites this device may also have an FM radio, an accelerometer, a proximity sensor and a compass. I haven't found or discovered those peripherals myself but I know the device has a vibrator which most websites fail to mention. It's not on the list because I haven't physically found it yet.
