Re: [Ports] New method to handle the device specific pixel ratio

 

Thanks, so much easier now! :)

Config for Asus Transformer Pad TF300T:

Filename: tf300t.conf
---
GRID_UNIT_PX=10
QTWEBKIT_DPR=1.6
FORM_FACTOR="tablet"
---

Hey,

We just landed a merge request [1] created by Oliver (ogra) that improves the way we're currently handling the device specific pixel ratio values.

The main idea is to move the device specific configuration from /usr/bin/ubuntu-session to a proper config file, in a way it won't be needed to change the original sources anymore.

As described at https://wiki.ubuntu.com/Touch/Porting#Screen_Pixel_Ratio, here's how you can create your device specific configuration file from tomorrow's image on:

First identify the ro.product.device android property used by your device (check the /system/build.prop file from your port or from the original Android image). Then with the desired DPR, create a file at /etc/ubuntu-session.d, adding your custom GRID_UNIT_PX and QTWEBKIT_DPR variables, also specifying the default form factor you want, such as:
$ cat /etc/ubuntu-session.d/manta.conf
GRID_UNIT_PX=20
QTWEBKIT_DPR=2.5
FORM_FACTOR="tablet"

Another good side effect is that people will be able to safely update the ubuntu-session package without breaking the previous device specific setup. Also, it make way easier to accept new contributions as all we need now is to add a config file to the session-manager package.

Also, please don't forget to send us the config file after you created it for your port, so we can include them in ubuntu-session by default.

Thanks.
