We are at almost end of 2016, unfortunately 2016 also took away great project with it, Cyanogenmod. However there is fork named LineageOS in pipeline. Given we switched our android base to CyanogenMod earlier, lots of people asked me how this will affect Plasma Mobile?
We used CyanogenMod source tree and kernel for generating minimal android system which is used in hammerhead port. All of them are available on github currently. However it is not clear that upto when it will be available and will receive updates given code review system (gerrit) for CyanogenMod is offline. At this point we have two options,
- Switch to LineageOS, given it is 1:1 fork of CyanogenMod currently it will not require much work.
- Switch to AOSP base, given we don’t really use the “extra” things provided by CM on top of AOSP.
While option 2 might sound big work, it in fact is not. For instance, in Nexus 5X (bullhead) port, underlying system is AOSP based instead of the CyanogenMod to simplify the things. Personally I had low priority task on phabricator for longterm to switch to AOSP base, but based on current situation this will need to be done with higher priority than earlier. :-(
That’s all for now, I hope this clarifies situation..
Currently Plasma Mobile is supported by very small number of devices, for example Nexus 5, and One plus one. These devices uses Android 5.0 or CM12 as their base. Current libhybris upstream doesn’t have support for the devices running Android 6.0 (Marshmallow), however there are two different forks of libhybris which are proposed to be merged into upstream libhybris and supports the Android 6.0,
This allows one to use Android 6.0 based binaries on normal Linux userspace and supports both armhf and aarch64 with some changes. I decided to try this on recent Nexus 5X device for which only Android 6.0 and higher version’s binary blobs are available. With some changes in KWin, for example : support for HWcomposer 1.4 and 1.5 and some changes in build infrastructure, it was possible to have Plasma working on Nexus 5X.

As of now, just graphics and input are supported on Nexus 5X, however I’ve plan to work on Network, calling and other functionalities in upcoming weeks, which is required to have usable system. However this is good step in direction of having support for more devices, as this will open the possibilities of supporting newer devices, I will be happy to help if someone wants to port/run Plasma Mobile on their device, feel free to contact me over email firstname.lastname@example.org or in #plasma channel on Freenode.

Hola Kubuntu users
Ubuntu ‘recently’ deprecated jockey and moved to ubuntu-drivers-common. ubuntu-drivers-common is a python backend which will try to figure out which drivers are best suited to your system. Up till Kubuntu 13.10 we were still relying on the backend called Jockey which is python2 , however for the 14.04 cycle, one of our major tasks was to rehaul the driver manager interface and use the fancy new ubuntu-drivers-common backend which is python3 based.
By leveraging this new backend, we are now at feature parity with Ubuntu when it comes to driver handling. Packages are now available to trusty users and can be acquired by installing the ‘kubuntu-driver-manager’ package.
Once installed you’ll find it in your System Settings Menu under “Driver Manager for Kubuntu”

Calligra sprint 2013 started today. The venue was Thoughtworks office Bangalore. I reached Thoughtworks around 10.45 AM. Shantanu had already booked a room at Thoughtworks for the sprint. There were 5 new faces for me in sprint. 4 were from DA-IICT College and Mani. We talked to each other for a while. Shantanu showed demo of calligra active. Fixed couple of bugs in active( more detail about them will follow in the next blog post). There was a major issue in sheets(when calligra active loads sheets) which we couldn’t resolve. Around 7.30 PM(IST), team in Europe arrived at Linux hotel. The first session was Krita BoF. And we did with help of google hangout. It was nice to see most of them. By 9 PM we had to move out of Thoughtworks. That was the time limit given to us. I had uploaded snaps of today here.
