Installation

Note No backend is available for user interface weston - it will boot to black/blank screen, see Weston troubleshooting.

Flashing kernel will fail

If you prefer installation from recovery zip, it will fail for the same reason: 

+ dd 'if=/mnt/pmOS/boot/boot.img' 'of=/dev/block/mmcblk0p31'
dd: error writing '/dev/block/mmcblk0p31': No space left on device

Fortunately, this occurs after rootfs has been written, so it is still possible to boot: 

$ fastboot boot boot.img

Aditional info

  • Screen is black on Wayland after the password is entered. Workaround:
sh /etc/postmarketos-mkinitfs/hooks/00-device-motorola-titan.sh

Note: this is obsolete, possibly replaced by: 

/etc/postmarketos-mkinitfs/hooks/00-msm-fb-refresher.sh
  • wifi: requires wcnss-service (see issue #373 and the wiki page Qualcomm MSM Interface) (this is installed by default if you choose to install nonfree firmware).
