I recently upgraded to an RX 480 and installed Ubuntu 16.10 gnome desktop. Because the default/open source drivers were glitchy, i downloaded the latest drivers from AMD's website, the 16.50 drivers, and after installing and rebooting all i can get to is TTY and Grub. If i do sudo service gdm restart it freezes. How do i fix this?
I have 14.04.5/16.04 or newer and an AMD GPU. I'm not getting the performance I want, and some programs say they need things like OpenCL.  I've heard about fglrx, but if I try to install it on my machine, it breaks and I have no GUI.  Is there anything I can do to get my AMD card working to its full potential?
Excluding empty(Null) fields when using EntityFieldQuery query condition Enroll Apple Developer Program under 18 I've seen a lot of questions like this throughout the web but they're mostly from 2 or 3 years ago, so I decided to ask to have some updated answers.   I'm 16 and I want to start publishing and using the benefits that comes with the Developer Program. In the legal agreement says that I should be over 18, and I'm not so, i can't do it. I've contacted the apple developer support and they told me that I should use a account in my father's name. We reside in Brazil. With that, I had some doubts:   Will the name on the App Store be mine or my father's? In the future, when I'm 18, this account can be transferred to my name?   Besides that, if someone has any advice or (legal) workaround I'd appreciate it, thanks Time complexity of nested for-loop I need to calculate the time complexity of the following code:  for (i = 1; i &lt;= n; i++) {   for(j = 1; j &lt;= i; j++)   {    // Some code   } }   Is it O(n^2)? Literature with Biber generates strange citations: firstnames appear erratically I had been using bibtex and then biblatex for quite some time. For the newest edition of my book I moved to biber. I happened t notice that firstnames are sometimes generated and sometimes not. Has this been observed by others?   I have tried to make a minimal example but without success. Using the following code, which shows all the commands related to biblatex I have in my preamble I could not get the firstnames to be shown. Even with the stylefile I made for this book (second line) the error did not occur.  I have a dropbox with the latex files for the book available. I can give access to these.

I have some cites in my captions. But I do not want to appear them in the table of figures or listings. With figures I managed to display an different caption like this:  \begin{figure}   \centering   \includegraphics[width=0.55\linewidth]{images/FIPA_Message-Transport-Reference-Model}   \caption[FIPA Message Transport Reference Model]{FIPA Message Transport Reference Model (\cite{FIPA2000}).}   \label{fig:FIPA_Message-Transport-Reference-Model} \end{figure}    But with lstlisting I have some troubles because the caption is an option of the listings and that seems not to have an optional caption label.  \begin{lstlisting}[ language=Scala, label={lst:Publisher}, caption={Publisher notify\cite{Zenger2013}}]    protected def publish(event: Evt) {     filters.keys.foreach(sub =&gt;       if (!suspended.contains(sub) &amp;&amp; filters.entryExists(sub, p =&gt; p(event)))         sub.notify(self, event)     )   } \end{lstlisting}   Any Ideas how to solve this?

Export Track Markers to csv I am trying to export markers from the Blender motion tracker and found the following script that will do exactly that:  for clip in D.movieclips:     for track in clip.tracking.tracks:         fn = 'data/tr_{0}_{1}.csv'.format(clip.name.split('.')[0], track.name)         with open(fn, 'w') as f:             frameno = 0             while True:                 markerAtFrame = track.markers.find_frame(frameno)                 if not markerAtFrame:                     break                 frameno += 1                 coords = markerAtFrame.co.xy                 f.write('{0} {1}\n'.format(coords[0], coords[1]))   It works but I have two questions:   How can I save the data on my Desktop rather than in folder in MacOS blender content where it saved right now. The following won't work:   fn = '/User/me/Desktop/data/tr_{0}_{1}.csv'.format(clip.name.split('.')[0], track.name) The resulting values I get do not represent the more user friendly marker values in den Blender GUI. Instead of x/y coordinates in screen coordinates, I get a value between 0/1. How can I convert them to those screen coordinates ?    Thanks for your help The StackExchange™ MultiCollider SuperDropdown™ says I've got replies, but I've already viewed those. Let $g_n= {2^2}^n +1 $. Prove $g_0 · g_1 · · · g_{n−1} = g_{n} − 2$ Let $g_n= {2^2}^n +1 $. Prove $g_0 · g_1 · · · g_{n−1} = g_{n} − 2$.    I'm not sure how to start this proof, if it should be done algebraically or if I should try to use a proof by induction. Do Mandalorians truly never remove their helmets? In episode 3 of The Mandalorian, it is said that Mandalorians never remove their helmets for any reason. Really? Not even to sleep or bathe? Is there any canonical source for this idea? I’m going to assume that the “never” implies “Never removes their helmets in public…” right?  But in flashback scenes to the Mandalorian’s childhood, nobody is really pictured wearing Mandalorian armor let alone helmets. They simply seemed like basic humans who might just be unified by wearing maroon wardrobes all the time.  So what is the deal with this claim? What is the canonical context of the claim?      Looking for in-universe, canonical explanations; not armchair speculation and theories. If none (currently) exist, legends explanation would suffice. Regardless, please provide references and context. Generalized Fresnel integral $\int_0^\infty \sin x^p \, {\rm d}x$ I am stuck at this question. Find a closed form (that may actually contain the Gamma function) of the integral  $$\int_0^\infty \sin (x^p)\, {\rm d}x$$  I am interested in a Laplace approach, double integral etc. For some weird reason I cannot get it to work.   I am confident that a closed form may actually exist since for the integral:  $$\int_0^\infty \cos x^a \, {\rm d}x = \frac{\pi \csc \frac{\pi}{2a}}{2a \Gamma(1-a)}$$  there exists a closed form with $\Gamma$ and can be actually be reduced further down till it no contains no $\Gamma$. But trying to apply the method of Laplace transform that I have seen for this one , I cannot get it to work for the above integral that I am interested in.   May I have a help? Possible to bake texture to new UV map?
