<div dir="ltr">Hi Rian - yes, we will eventually address the running as root issue. In fact in the touch configuration we'll soon have a nested mir setup (or mir-on-mir), where one is associated with the user session for unity8 and the other as root which the greeter will be using (as the system compositor).<div>

</div><div><br></div><div>I am a little confused though. If Mir is to replace X someday, clients will have to be able to be run as non-root. The ideal solution is where both the server/compositor, and clients are running as non-root which is one of the things that X doesn’t do today. Are there plans to fixing the privilege issue (everything needing root), or am I not understanding something.

</div><div><br></div><div>Q: How does Mir handle surfaces with shapes cut out of them. For<br>example, a smiley face where the background is shown through the eyes<br>and mouth.<br>A: Create your surface with an alpha channel (e.g.<br>
mir_pixel_format_abgr_8888) and then any pixels with alpha==0 will be<br>transparent. As an example of a free-form shape, you can run:<br>mir_demo_client_egltriangle -b 0.0
</div><div><br></div><div>Q: Do clients need to have root access. For the fingerprint test, I<br>could not get it to run without a sudo.<br>A: Yes and no. A client can run as the same user as the server,<br>including non-root. This works perfectly for touch (Android) devices<br>
however desktop has the problem of requiring root to access input<br>devices. You can run mir server and client on desktop as non-root but<br>you won't be able to interact with it.

</div><div><br></div><div>For others interested in how I got Mir up and running, here were my steps:
</div><div><br></div><div>1:<br>Install the 3.13 linux kernel.
