Ubuntu Touch is a new mobile interface for Ubuntu being developed by Canonical. Its main purpose is to bring the Ubuntu experience to touchscreen devices. Applications that run on the desktop version of Ubuntu will also be able to run on the mobile version and vice versa. Mobile devices with Ubuntu Touch can also be used to provide the full desktop Ubuntu experience by simply connecting it to an external monitor and attaching the necessary peripherals.
Over at the xda forums an experimental port of the Ubuntu Touch has just been released for the Xperia Tablet Z. Most of the features of the tablet are working such as its Wi-Fi, touchscreen, and camera among others. There are however a few bugs still present such as inability to record video, or the camera app freezing when started but works fine after about a minute. These bugs are expected in any experimental build. The best part of this is that it can be dual booted with CyanogenMod.
If you own an Xperia Tablet Z and would like to tinker around with the OS by installing Ubuntu Touch then make sure that you have a firm grasp of the concepts involved in flashing ROMs. Installing Ubuntu Touch is just like installing CyanogenMod so if you have experience in performing the latter then it’s going to be easy to perform.
Warning: Before proceeding with the install make sure to make a back-up of your important files. This is still an experimental build and is not advisable for daily use.
